Date: 17~18th January 2026 (Saturday ~ Sunday)
 
 
After leaving Kurayoshi, I drove straight to Misasa Onsen (三朝温泉). Once we entered Misasa Town, we followed the northern bank of the River Mitoku (三徳川) all the way. When we reached the junction by Misasa Bridge (三朝橋), we didn't cross the bridge but continued straight ahead. Before long, we saw a large sign spanning both sides of the road. It marked tonight's accommodation – San'in Misasa Onsen Izanrô Iwasaki (山陰 三朝温泉 依山楼 岩崎). Along the stretch of the northern bank of the River Mitoku between Misasa Bridge and Koitani Bridge (恋谷橋), there are only two buildings, both of them ryokan. Ours was one of them (and by far the larger one).
 
We arrived from Kurayoshi in less than half an hour, at around 17:00. When we pulled up outside the ryokan, I first told the staff that we were checking in. He pointed us towards the car park, which was only about another 100 metres further along the road, and suggested we park there before returning. We explained that we'd like to unload our luggage first so that Todd could go inside while I parked the car on my own. The staff smiled and said, 'Daijôbu' (that means 'no problem' or 'don't worry' in Japanese), meaning that was absolutely fine and would save us from dragging our luggage all the way back from the car park. However... Todd had left his bag in the car... and his passport was inside it, so he couldn't actually check in first after all!

Walking into the ryokan immediately gave us a strong feeling of the Shôwa era. The reception desk is just to the right of the entrance (I only realised while sorting through the photos afterwards that I'd forgotten to photograph the front desk). The lobby itself is quite spacious, with a corner dedicated to tourist information about Misasa Onsen and Mount Mitoku (三徳山). Opposite the front desk are two guest lounges: the riverside lounge 'Myôjô' (明星), overlooking the river, and the garden lounge 'Shirakaba' (白樺), overlooking the gardens. Between them is Gallery Iwasaki (ぎゃらりい岩崎).
 
Izanrô Iwasaki is a ryokan with a long history and an excellent reputation. Over the years it has welcomed many members of the Imperial Family, politicians and famous literati. Gallery Iwasaki displays original calligraphy and paintings presented to the ryokan by many of these distinguished guests. Among them are works by Emperor Taishô (大正天皇, when he was still Crown Prince), Emperor Shôwa (昭和天皇) and Empress Kôjun (香淳皇后), as well as those by former Prime Minister KONOE Fumimaro (近衛 文麿), whose cabinet led Japan into the World War II. (Many people mistakenly believe it was TÔJÔ Hideki (東条 英機) who started the war, but Tôjô actually succeeded Konoe. After Emperor Shôwa announced Japan's surrender, Konoe committed suicide by taking poison before he could be tried, and he was therefore never prosecuted or listed as a war criminal.
 
Layout of Izanrô Iwasaki (Image source: official ryokan website)
 
The ryokan is made up of three fully connected sections. The western wing is eight floors high and is called Sansuikaku (山水閣). The eastern wing has six floors and is called Tôzankaku (東山閣). The central section is a little more unusual. Although it has seven floors, the entire 7/F and part of the 6/F belong to Sansuikaku guest rooms (as shown in the layout above). The remaining modem Japan-Western style rooms are known as Futaba (双葉) rooms, while the less desirable rooms in terms of location and view are grouped under the Honkan (本館, main building). These are all traditional Japanese-style rooms (no beds, only beddings on tatami mats) and are only available as room-only or breakfast-included plans.
 
We booked a Futaba Japanese-Western style room with a semi-open-air bath, which is one of the ryokan's mid-range room categories. Our package was an early booking offer made more than 30 days in advance. It included both breakfast and dinner, served in a private dining room. The package description particularly highlighted 'Enjoy a seasonal kaiseki course at Saryô Hanano, where quality take priority over quantity.' (量より質の懐石を堪能できる「茶寮花野 季節の懐石」) This plan had to be paid online in advance and could not be paid upon arrival. The total cost for two people was JP¥77,000 (with an additional JP¥150 per person hot spring bathing tax payable at check-in).

There are only two rooms of this type in the entire ryokan – Rooms 505 and 605. So don't panic if a booking website says 'Only 2 rooms left'! We were assigned Room 505. Our nakai (a housekeeping member in a ryokan) escorted us to the room with our luggage, showed us where the yukata were kept, handed us the room key, and then left. Unlike at some ryokan, she didn't explain all the facilities in the room (although, to be fair, they're much the same everywhere).
 
As with most Japanese rooms, the entrance naturally begins with a genkan (玄関). Normally there's a single raised step separating the shoe area from the barefoot area, and many people even sit on that step when putting on their shoes. This room was slightly different. Instead of a step, there was a gentle ramp, probably to make wheeled luggage easier to move. However, it also made the boundary between the shoe area and the barefoot area felt much less obvious. Directly opposite the entrance was a sliding door leading to the toilet. As in most ryokan, the toilet is located in the entrance hall. The doorway into the main living area was on the right.

Tatami area
 
Hiroen (veranda-style sitting area). The sliding doors behind the bench lead to the bathroom and the semi-open-air bath
 
The room measures 35.2 m2, with a 7.5-tatami living area laid out using Ryûkyû tatami, the square chequerboard-style mats. Besides the low Japanese tea table, there was also a standard-height bench where you could comfortably sit and watch TV. (I don't know whether anyone else is like me, but even though I don't understand everything, I still really enjoy watching Japanese TV programmes, especially the local channels. Somehow it's only in Japan that I do this – I never deliberately watch hotel TV in Britain)
 
The bathroom area is separated by sliding doors. Inside, you first come to the washbasin, while the door on the right leads into the bathing, which includes both a shower and the semi-open-air bath. The bath in the room is supplied directly with free-flowing natural hot spring water. (Some ryokan only provide ordinary tap water in their private baths, though they usually make that clear in advance.) For toiletries and skincare products, many ryokan use local brands or even their own in-house products. Here, however, they provide products from the well-known brand POLA.

Next to the tatami area (separated only by a wall from the bath), is the hiroen (広縁), which contains a dressing table and full-height windows. The windows can be opened, and outside is what could perhaps be call a 'balcony' – although 'platform' would probably be a better description. The floor is permanently wet, so you certainly wouldn't want to step outside. Its main purpose is drainage. When the bath overflows, some water drains away through the bathroom, but most flows onto this outdoor platform before being carried away through external drains.
 
The ryokan's rooms are mainly divided into river view (River Mitoku, also known locally as the River Misasa) and mountain view rooms. This is clearly stated when making your booking. Generally speaking, the river view is considered better, but in autumn the mountain side has the advantage of overlooking the autumn red maple colours.

Entrance and exterior of the ryokan
 
Izanrô Iwasaki was founded in 1920, originally under the name 'Iwasaki Ryokan'. It was later renamed Izanrô by HASHIMOTO Dokuzan (橋本独山), the chief abbot of the Rinzai school's Shôkokuji branch, one of Kyoto's Five Great Buddhist Temples. Izanrô literally means 'mountain-side mansion', reflecting the Zen ideal of living close to both mountains and water, while also perfectly matching the ryokan's surroundings. Since there is a 'mountain-side mansion', there should naturally also be 'water', so the ryokan's garden was named Isuien, meaning 'water-side garden'.
 
Today, Isuien is designated both a Tottori Prefectural Scenic Site and a Misasa Town Scenic Site. Within the garden stand two separate buildings: Sanchôkaku (三朝閣), a quiet detached guest suite whose name was given by the Duke TOKUGAWA Iesato (徳川 家達), the 16th Head of House of Tokugawa. Sanchôkaku was reserved exclusively for Emperor Shôwa during his two stays here. Fusôan (扶桑庵), a traditional thatched tea house built in the early Shôwa period by the Kyoto tea-house master craftsman KIMURA Seibei (木村 清兵衛).

Our ryokan, Izanrô Iwasaki, is on the north bank of the River Mitoku
 
As we had arrived fairly late, it was already beginning to get dark after we'd settled into our room. We decided to go out for a walk before nightfall, which meant we didn't have time to visit Isuien, the garden in the ryokan. After crossing Misasa Bridge, we came across a statue dedicated to Misasa Kôta (三朝小唄). Originally written in 1927 by the lyricist NOGUCHI Ujô (野口 雨情), Misasa Kôta is a traditional Japanese folk song describing the scenery of Misasa Onsen.
 
Two years later, in 1929, a silent romance film of the same name was released. It tells the story of a Tokyo painter holidaying in Misasa Onsen who falls in love with a local young lady. Although the relationship ultimately could not overcome the differences in their backgrounds, the film made Misasa Onsen famous throughout Japan and helped established it as what is now the second most popular hot spring town in Tottori Prefecture.
 
Between the Misasa Bridge and the statue is a flight of steps leading down to the riverbed. There you will find Kawara Buro (河原風呂), a free open-air public hot spring bath. Although it is in a public place, it is a mixed-gender bath where everyone bathes naked. It is quite similar to Sunayu (砂湯), the free open-air bath at Yubara Onsen in Okayama Prefecture that I visited in 2017. Personally, though, I think the one at Yubara Onsen is a bit more special because it sits directly below a hydroelectric dam. As I'd already experienced an outdoor mixed bath before, I decided to give this one a miss.

According to local legend, ÔKUBO Samanosuke (大久保 左馬之祐), a retainer of MINAMOTO no Yoshitomo (源 義朝), rescued a white wolf while on his way to visit Mitokusan Sanbutsuji (三徳山 三仏寺, a famous Buddhist temple near Misasa Onsen). The white wolf turned out to be the incarnation of Myôken Bosatsu (妙見菩薩), who guided him to a hot spring. Samanosuke discovered hot water flowing from beneath a camphor tree, and the spring became known as Kabuyu (株湯), meaning 'Spring of Tree'.
 
The water at Misasa Onsen is crystal clear, silky smooth, and truly one of a kind. It is classified as a simple spring and a sodium bicarbonate spring, and contains radon at concentrations of up to 702 mache units, making it one of the highest-radon radioactive hot springs in the world. It is said to have excellent healing properties (although every hot spring seems to claim that!). According to local tradition, if you bathe here for three consecutive mornings, your illness will heal without medicine. This is said to be how Misasa got its name. (Misasa literally means 'three mornings'.)
 
Onsen Hondôri
 
Shibai Goya New Lucky
 
The lane beside the Misasa Kôta statue is the town's high street, Onsen Hondôri (温泉本通り). Not only does our ryokan, Izanrô Iwasaki, still have a strong Shôwa-era vibe, but the whole of Onsen Hondôri also feels as though it has been frozen in the Shôwa period. The street is only around 300-400 metres long, lined with family-run ryokan, old liquor shops, traditional shooting galleries, dagashiya (old-fashioned sweet shops), coffee shops and craft shops. We arrived rather late, so most of them had alredy closed for the day, but the nostalgic vibe was still very much there and made the stroll thoroughly enjoyable.
 
Among all the shops, one immediately caught our attention, Hanging beneath bright red lanterns was a place called Shibai Goya New Lucky (芝居小屋ニューラッキー). Both its appearance and its name gave off quite a dirty vibe. In fact, it really was once an adult entertainment venue – a strip theatre – and was the last establishment of its kind to remain open in Tottori Prefecture. Today it has been turned into a venue for rakugo (落語), Japan's traditional form of comic storytelling, under the name Misasa Yose (三朝寄席). However, to preserve the nostalgic character of the hot spring town, the old signboard and facade have been left untouched, with only a vertical Misasa Yose banner displayed on performance days.
 
Slogans in a style often associated with Japanese right-wing groups
 
The Rising Sun flag makes it look even more right-wing
 
Continuing further along Onsen Hondôri, we spotted a large Rising Sun Flag (旭日旗), a Hinomaru (日の丸, the Japanese national flag), and several bold slogans in the distance. At first glance, it looked very much like the sort of publicity often associated with Japanese right-wing groups. I initially though it must be the office of some nationalist organisation, but it turned out to be a ryokan called Saitôkan (西藤館). According to Japanese websites, the owner is simply a self-described patriot and chose to display the slogans himself.
 
Reading them more carefully, however, they were not really as extreme as I had expected. Messages such as 'Take back Japan's territory' and 'Let us always think about our country, Japan, remember that we are Japanese, and face this national challenge with patriotism' actually seemed much milder than the political slogans often seen on the streets of China. In the open space outside Saitôkan stands a pillar listing places associated with 'Japanese Nationalists', as well as towns that have friendly ties with Misasa Onsen. Among them are Shigang District (石岡區) in Taichung, Taiwan, and Lamalou-les-Bains in the French department of Hérault.

Kiya Ryokan
 
Looking at the reactions of both Japanese visitors passing by and Japanese travel bloggers online, most people seemed to keep their distance from these displays rather than support them. That alone shows how far removed reality is from the image often presented by the Chinese government of a 'resurgent Japanese far right' or a 'revival of Japanese militarism'.
 
There are several old ryokan along Onsen Hondôri, one of the best known being Kiya Ryokan (木屋旅館). It has no grand entrance, and from the outside it looks much like the ordinary old houses nearby. Yet it is actually the oldest and most historically significant ryokan in Misasa Onsen. Founded in 1868, it has remained family-run ever since and still retains its original Meiji-era buildings, rather than being rebuilt or modernised like many other ryokan. Today it is registered as a Registered Tangible Cultural Property of Japan.
 
Yakushidô is just ahead
 
Yakushidô and Yakushinoyu
 
Halfway along Onsen Hondôri stands Yakushidô (薬師堂), dedicated to Yakushi Nyorai (薬師如来), the Medicine Buddha. In fact, many historic hot spring towns have a hall dedicated to Yakushi Nyorai, as hot springs have traditionally been associated with healing, and the Medicine Buddha is regarded as the protector of such places. The exact date of the hall's foundation is unknown. Inside is a seated wooden statue of Yakushi Nyorai, affectionately known by the locals as 'Yu Yakushi-san' (湯薬師さん, similar to 'Dr Spring'). According to legend, the statue was originally enshrined at Mitokusan before being moved here.
 
Outside Yakushidô is Yakushi-no-Yu (薬師の湯), which includes both a footbath and a drinking spring. It is one of Misasa Onsen's five free hot spring facilities. The other four are Kawara Buro (the free open-air bath and footbath mentioned earlier), Kabuyu ( a paid public bath with a free footbath and drinking spring), the hot spring chôzuya (purification basin) at Misasa Jinja (a Shinto shrine), and the footbath on Kajika Bridge, which is closed from mid-December to March. Yakushi-no-Yu itself is quite small, but once the lanterns are lit in the evening, it has a wonderfully vibe, almost as if you've stepped into the world of the Japanese animation movie, Spirited Away (千と千尋の神隠し).

The souvenir shop inside the ryokan – San'in Miyage
 
By the time we left Yakushidô, it was completely dark, so we headed back to the ryokan for the first kaiseki dinner of this trip. After returning, we still had a little time fore dinner, and the souvenir ship inside the ryokan was still open, so we had a look around first. It was much like the souvenir shops at Michinoeki (道の駅, roadside stations) or tourist attractions, selling very similar products at much the same prices.
 
When it was nearly time for dinner, we went back to our room to change into our yukata before heading downstairs. Dinner was served in the private dining restaurant Saryô Hanano (茶寮 花野) on the 3/F. When we checked in, the reception staff had already told us that our private dining room would be Ishibuki (石蕗). As we were overseas visitors, they had thoughtfully written the room name in Roman letters as 'Ishibuki' on our welcome guide. It looked considerate enough, although in practice it wasn't particularly useful (haha)... because everything inside the restaurant was still written in Japanese. (Perhaps it was simply to make it easier for us to tell the staff which room we were in.)
 
Dinner venue – Saryô Hanano
 
Shoe storage area for each private dining room at the entrance to Saryô Hanano
 
Our private dining room – Ishibuki
 
Besides Saryô Hanano, the ryokan also has another dining area on the 2/F called Taishintei (對岑亭), which is mainly used for banquets. Saryô Hanano consists of small private rooms for parties of up to four people, while Taishintei has a large banquet hall as well as medium and large private rooms for groups of five or more. Guests booking the more expensive 'Seasonal Kaiseki' package are served in a private room at either Saryô Hanano or Taishintei, depending on the size of their party. The more affordable 'Iwasaki Kaiseki' package is served in Taishintei's banquet hall. Besides the different dining settings, the menus also differ slightly – the former is more refined, while the latter is a little simpler.
 
Since the restaurant is called Hanano (literally 'Flowers Field'), all of the private dining rooms are named after flowers. There are seventeen in total, and ours was called Ishibuki, the San'in dialect pronunciation of the plant known in standard Japanese as Tsuwabuki (Farfugium japonicum, leopard plant).
 
Next to the entrance of Saryô Hanano is a shoe storage cabinet. Each dining room has its own basket labelled with both the room name and the guests' surname. The same surname is also displayed outside the dining room itself, making it very easy to find your room.
 
Inside our private dining room, with some of the dishes and the aperitif already prepared
 
Each seat has its own menu
 
Our drinks, I always like ordering lemonade when staying at a Japanese ryokan
 
By the time we entered our room, the starters and several other dishes had already been laid out. Once we were seated, our nakai first handed us the drinks menu. I almost always order lemonade, and Todd couldn't be bothered choosing, so he simply ordered the same. Our drinks arrived within minutes, after which the nakai briefly introduced the dishes already on the table. The menu had already been placed at each seat. Since we were foreign guests, the ryokan kindly provided both the original Japanese menu and an English translation. Ironically, as Chinese speakers, we actually found the Japanese version easier to understand.
 
From the aperitif through to the pickles and dessert, tonight's kaiseki consisted of fourteen courses in total. Although the ryokan modestly described it as 'quality over quantity', I personally thought it delivered both.
 
Aperitif: Pear wine
 
Starter: Salmon mizore-ae (Salmon with grated daikon radish)
 
Entree: Turban shell grilled with salted sea urchin, rolled omelette, squid with mentaiko, cream cheese wrapped in cured ham, and salt-koji grilled red fish (hidden behind the leaf)
 
Entree: Shiokara squid
 
Entree: Baby scallops with chili oil and miso
 
Sashimi: Four seasonal selections served in a 'hot spring steam' style – striped jack, squid, flounder and mosa ebi prawn
 
The starter, salmon mizore-ae (サーモンみぞれ和え), was simply salmon mixed with grated daikon radish (or calls mooli radish in Britain). Mizore literally means sleet, but in Japanese cooking it refers to grated daikon because of its resemblance to melting snow. 'Ae' generally refers to ingredients mixed with a dressing.
 
Among the entrees, my favourite was the turban shell grilled with salted sea urchin. Besides the fact that I simply love sea urchin, the turban shell itself had an intense taste of the sea and plenty of natural umami. The shiokara squid was rather heavily seasoned. Personally, I thought it was a little too strong for an entree, especially considering that sashimi was served immediately afterwards.
 
Once we had almost finished the starter and entrees, the nakai cleared away the plates before bringing us the sashimi course, featuring striped jack, squid, flounder and mosa ebi – all among Tottori's finest local seafood. The plate was filled with dry ice to create the effect of rising hot spring steam, which is why the dish was described as Yukemurishitate (湯けむり仕立て, means hot spring steam style).
 
Interlude (Oshinogi): Crab stick sushi
 
Soup course (Owan): Crab claw, ebi-imo taro and tochi mochi
 
Grill: diced Tottori Wagyu steak
 
After the sashimi came the oshinogi (お凌ぎ), a small carbohydrate dish served between the earlier and middle courses. It provides a little break in the meal and gives diners a slight sense of fullness. It is usually one or two pieces of sushi or perhaps a small bowl of soba noodles. Of course, the 'crab stick' here was not imitation crab stick (the seafood stick in supermarket), but freshly hand picked crab leg meat.
 
Next came the owan (お椀), consisting of crab claw, ebi-imo taro and tochi mochi in a clear broth. Although owan is often a soup course, it doesn't have to be. As long as the dish is served in a traditional lacquer bowl, it is considered an owan. Sometimes it may even be a simmered dish. If it is soup, the difference between owan and oshiru (お汁) is that owan focuses on the ingredients themselves, whereas oshiru focuses mainly on the soup, with the ingredients being optional to eat. Tochi mochi is a type of rice cake from Japanese horse chestnuts (tochi-no-mi) and glutinous rice.
 
A few days earlier, when we ate at Yakiniku Gyûô (焼肉 牛王), I had already introduced Tottori wagyu. Tonight's grilled course featured it once again, so I won't repeat the story here (you may read my previous article here).
 
Fries: Blackthroat seaperch, deep-fried pufferfish, and green chili pepper
 
Hot pot: Pacific cod and scallops in a light shio pot
 
The fried course included both pufferfish and nodoguro (blackthroat seaperch), together with a piece of green chili pepper! I absolutely hate green peppers, so I happily left that behind. I've had pufferfish as sashimi, in soup and dried before, but this was my first time trying it deep-fried. Personally, I think pufferfish is one of the most overrated luxury ingredients. I completely disagree with comments such as 'worth risking your life to eat'. Perhaps I've simply never had truly exceptional wild pufferfish. Nowadays, however, most pufferfish served in restaurant are farmed and naturally toxin-free, making them perfectly safe to eat. That's why some people jokingly complain that 'only wild ones taste good!'
 
Compared with pufferfish, nodoguro (のどぐろ) is actually far more representative of the San'in region and is one of Tottori's signature autumn fish. Taiwan also has a fish known as blackthroat, but it is a completely different species. The Taiwanese 'blackthroat' refers to black scraper, while the Japanese nodoguro is blackthroat seaperch (Akamutsu), known in Taiwan as redthroat. Nodoguro is rich in fat, wonderfully full of umami, and has a silky texture that stays moist even after deep-frying.
 
The hot pot was a Shio Kogonabe, a small hot pot seasoned mainly with salt. 'Shio' can means 'salt' in Japanese, so the name essentially means a lighty salted hot pot. Standard ingredients include crown daisy, Chinese leaf, leeks and enoki mushrooms.
 
The main ingredients this time were Pacific cod and scallops. As someone living in Britain, cod is nothing unusual – if a portion of fish and chips doesn't specify the type of fish, it is almost certainly Atlantic cod. Here is Japan, however, cod naturally refers to Pacific cod. Atlantic cod has a firmer texture and a richer flavour, making it well suited to grilling and frying, while Pacific cod is milder and more delicate, making it better suited to steaming or simmering.
 
Vinegared dish (Sunomono): Steamed snow crab casserole
 
Steamed snow crab served with crab vinegar (the smaller sauce plate contains soy sauce for the sashimi)
 
The star of the entire meal was arguably the steamed snow crab, listed under the sunomono course. It only appears on the winter menu, during the snow crab season from November to March. In this case, sunomono does not necessarily mean food prepared with vinegar. It can also refer to dishes served with vinegar as a dipping sauce, such as fresh firefly squid or black geoduck clam in spring. We had already enjoyed one whole snow crab at Karoichi Market earlier today, and now we were eating another one. It really had become our day of the crab.
 
Japan inherited more than just Gofuku (呉服). Gofuku originally silk garments imported from Go region (, an ancient kingdom or regime in eastern China, almost the provinces of Kiangsu (or Jiangsu) and Chekiang (or Zhejiang), and Municipality of Shanghai today; and '吳' now is pronounced as 'Wu' in modern Mandarin Chinese), now meaning fine silk traditional Japanese clothing. It also adopted the custom of eating crab with vinegar.
 
After all the course had been served, the meal concluded, as most ryokan banquets do, with rice, pickles, miso soup and dessert. Dessert was a hôjicha pudding ('hôjicha' means roasted tea) made with Daisen White Rose Milk, giving it a pleasant local touch.
 
Rice: Premium Misasa Koshihikari rice (pearl rice); final soup (Tomewan): Red miso soup with locally grown nameko mushrooms; pickles (Kônomono): Takana mustard greens and crisp pickled daikon
 
Dessert: Hôjicha pudding (made with White Rose Milk)
 
Tea after the meal
 
After dinner, we went back to our room for a short rest before heading to the public bath for a shower and enjoy the hot spring bath. The ryokan's bathhouse is called Yama-no-Yu (山の湯), which the ryokan describes as a 'strolling-style large garden open-air bath'. It is divided into the Left Bath (左の湯, Hidari-no-Yu) and the Right Bath (右の湯, Migi-no-Yu), with each side alternating between the men's and women's baths depending on the date. The bath is open from 15:00 to midnight. At 05:00 the following morning, the men's and women's sides are swapped, and both remain open until 10:00. During our stay, for example, the men's bath was the Right Bath that evening, but the following morning we had to use the Left Bath instead. (There are signs at the entrance showing which side is for men and women.)
 
Most ryokan only have one indoor bath and one open-air bath, but things are rather more elaborate here. The Right Bath includes the main public bath Rakuzan-no-Yu (楽山の湯), the two open-air baths Jinsha-no-Yu (仁者の湯) and Chisha-no-Yu (智者の湯), as well as the indoor bath Rakusui-no-Yu (楽水の湯). Rakuzan-no-Yu is the largest bath in the ryokan. Its bath is lined with large natural rocks, and although is technically an indoor bath, it sits within a traditional sukiya-style building. Large glass panels on both sides allow it to blend seamlessly into the surrounding Japanese garden.
 
As mentioned earlier, Misasa Onsen is one of the world's best-known radon-rich hot springs, with naturally high levels of dissolved radon gas. Radon is a radioactive gas produced by the decay of radium. According to the ryokan, radon stimulates the body's cells and activates their functions, producing what it calls a 'hormesis effect', helping to strengthen the body's natural healing ability. The ryokan recommends experiencing the therapeutic benefits of Misasa Onsen in three ways: bathing in the water, drinking the spring water, and inhaling the radon-rich air.
 
Entrance to the hot spring baths
 
Drinking spring
 
While soaking in the hot spring, radium is absorbed through the skin. At the same time, the ionising effect of radon creates negative ions in the air, giving the atmosphere a feeling rather like walking through a forest. The spring water at Misasa is also rich in minerals. Drinking it is said to increase blood flow to the stomach lining, and help relax the stomach. Finally, when radon is inhaled into the lungs, it enters the circulatory system, where it is said to stimulate cell metabolism and improve the body's antioxidant function. According to the ryokan, this may help prevent the effects of ageing and health problems caused by an irregular lifestyle. I should stress, however, that everything above is simply what the ryokan states in its own information.
 
Those living in Britain may notice something rather interesting here. In Britain, radon is generally regarded as a health hazard rather than a health benefit. Because of the geology in may parts of the country, radon gas can seep naturally from the ground. If a house is poorly ventilated, the gas can build up indoors and cause serious health problems, including lung cancer. The British health authorities regard radon as the second leading cause of lung cancer after smoking. That said, the information provided by Misasa Onsen is based on research carried out by Okayama University (岡山大学), and refers to occasional, controlled exposure to low levels of radon. This is quite different from the long-term accumulation of radon inside poorly ventilated homes that the British authorities are concerned about.
 
It was incredibly cold that evening (perhaps because Misasa Onsen sits in a mountain valley), so we spent most of our time in the two indoor baths, Rakuzan-no-Yu and Rakusui-no-Yu. Even in the open-air baths, although the rest of your body was submerged in the hot spring, everything above your shoulders still felt freezing! After our bath, we each drank two large cups of the spring water before returning to our room to relax and sleep.
 
Breakfast
 
Three small side dishes: hijiki seaweed with nori, mushrooms with miso and yuzu, and dried shredded daikon
 
After getting up and freshening up, it was naturally time for breakfast. When we checked in, we had already chosen the 07:30 breakfast sitting. (Breakfast at an onsen ryokan is usually served quite early, generally before 08:00.) We dined in the same place as the previous evening, our private room Ishibuki in Saryô Hanano on the 3/F. When we arrived, almost all of the dishes had already been laid out on the table, together with the breakfast menu. Unlike dinner, however, there was no English translation. (Unless you cannot read any Japanese or Chinese characters at all, it does not really make much difference!)
 
Regardless of which accommodation package guests book, everyone is served exactly the same breakfast. The only different is where you eat. Apart from the rice and the fruit juice served at the end, the breakfast consisted of ten dishes. To begin with were three small starters. Although each had quite a rich flavour, none of them left a strong aftertaste, so the flavours did not linger in the mouth. They worked very well as a light starter to stimulate the appetite.
 
Sashimi: squid (yari-ika)
 
Middle dish: Kurayoshi momen tofu
 
Grill: overnight-dried horse mackerel and locally made tofu chikuwa
 
The sashimi this morning was yari-ika, a type of squid. Hong Kong people often become completely confused when they see names and type of squids in Taiwan. In Hong Kong, all of these are simply called 'squid', although people still distinguish between squid and cuttlefish. Japan is even more general in its naming, as almost everything is simply called ika (イカ). It is actually quite rare to see the specific species written, as it was here with yari-ika. Sometimes, when writing my travel articles, I even struggle to decide whether ika should be translated as 'squid' or 'cuttlefish'.
 
Tofu is almost an essential ingredient in a traditional ryokan breakfast. Misasa Onsen is close to Kurayoshi, which is well known for its tofu, so this breakfast featured Kurayoshi Momen Tofu. Momen tofu is similar to the firm cotton tofu commonly found in Hong Kong and Taiwan. It has a dense texture and a rich soybean flavour.
 
Another dish that appears very frequently at ryokan breakfast is ichiyaboshi (一夜干し, overnight-dried fish). This time it was made with horse mackerel. In the San'in region, however, it is often served together with tofu chikuwa. Ordinary chikuwa is made from fish paste, but in San'in, tofu is mixed into the fish paste to create this local speciality. That is why you will often see chikuwa being sold even in local tofu shops around Tottori.
 
Simmered dish: country-style takiawase
 
Steamed dish: chawanmushi with plum
 
Small bowl: vegetable salad
 
Hot dish: miso clam soup
 
Side dish: Izanrô Iwasaki's homemade roasted nori
 
Rice: premium Misasa Koshihikari rice
 
Pickles: Hiroshima greens and shibazuke
 
Drink: apple juice
 
Another ingredient that seems to appear in ryokan breakfasts surprisingly often is small aubergine. Although it is prepared in different ways, it somehow always seems to make an appearance. This morning it was included in the simmered dish, country-style takiawase, which is rather similar to oden. A variety of simple countryside ingredients are gently simmered together in a seasoned broth, with no fixed combination of ingredients. This version included small aubergine, squash, daikon and hiryûzu (tofu puff with vegetables stuffing). The remaining dishes felt fairly ordinary and were all things you could easily find elsewhere. The one with the strongest local flavour was the miso clam soup, which we had encountered almost every morning while travelling around San'in. It was always very enjoyable.
 
One slightly unusual thing was that the individually wrapped roasted nori counted as a dish in its own right (although it was packaged by ryokan itself). You could wrap it around the rice or simply add it to the soup. Breakfast finished with a glass of apple juice rather than fresh fruit, which somehow made it feel as though something was missing. Overall, it was certainly a generous breakfast, but it did not contain many surprises. Compared with dinner, the evening kaiseki meal was definitely the more memorable dining experience.
 
After breakfast, it was naturally time for one last hot spring bath before checking out. We could have tried Left Bath, as the men's and women's baths had swapped over that morning. However, since our room had its own private hot spring bath, we decided not to. After enjoying one final bath, we checked out and set off for our first destination of the day – Yura Station (由良駅).
