A Summary of Kusatsu Onsen

Kusatsu Onsen is located halfway up Mt. Kusatsu-Shirane near the border of Nagano Prefecture. The hot spring town, located at an altitude of 1,200 meters, has been a famous place where the Japanese go to cure serious injuries and chronic diseases. Together with Kobe‘s Arima Onsen and Gifu‘s Gero Onsen, they are known as the Three Most Famous Onsen in Japan. Many well-known Japanese historical figures such as Yamato Takeru no Mikoto (日本武尊), Minamoto no Yoritomo (源頼朝), Tokugawa Ieyasu (徳川家康), and Toyotomi Hideyoshi (豊臣秀吉) all benefited from the health benefits of Kusatsu Onsen’s strong acidic hot spring.

In the Edo period (1603 – 1867), Kusatsu’s hot spring was one of the tributes the province offered to the Shōgun of Tokugawa shogunate, including the 8th Shōgun, Tokugawa Yoshimune (徳川吉宗) and the 10th Shōgun, Tokugawa Ieharu (徳川家治).

What distinguishes Kusatsu Onsen from other hot spring resorts in Japan is Yobatake (湯畑), where hot spring continues to gush out. Ryokans, hotels, restaurants, and shops are gathered around this symbol of the onsen town.

In addition to being a hot spring resort, Kusatsu Onsen is also a summer resort. And although many international tourists aren’t aware of it, you can also ski and snowboard at Kusatsu Onsen! But just note that Kusatsu Onsen’s hot spring is sulphur based. So if you dislike the smell or find it unpleasant, it might not be the hot spring resort you would want to visit.

How to Get to Kusatsu Onsen

To get to Kusatsu Onsen by public transportation from Tokyo or the Kansai region, there are a couple of methods. The easiest way is to take the express bus. But, if you have a JR Pass covering the hot spring town, you can get there with no extra charges by using the train + bus method.

Together they are known as Kusatsu Santō, all for same-day visitors and are sourcing onsen from one of Kusatsu’s six main hot spring sources. You can even experience Kusatsu’s traditional bathing method in one of the bathhouses!

For more information, refer to our Guide on Sainokawara Street!

Kusatsu Onsen Bus Terminal (草津温泉バスターミナル)

Ⓒ photo-ac.com

Your first stop at Kusatsu Onsen will likely be Kusatsu Onsen Bus Terminal. The facility is more than just somewhere to park the bus. It is equipped with restaurants, souvenir shops, and even a hot spring library (温泉図書館) on the third floor!

The diorama demonstrates Kusatsu Onsen’s historical photos and traditional bathing methods in the library, although English notation is limited.

In addition to local buses, Kusatsu Onsen Bus Terminal is also where your hotel/ryokan can pick you up if they provide this service (a reservation is usually required to utilize it).

For those who don’t hold a JR pass, we recommend purchasing your JR train ticket back to Tokyo at Kusatsu Onsen Bus Terminal’s ticket counter. Why? So you can get a ticket with Kusatsu Onsen Station (草津温泉駅) printed!

Just note there is no train station called Kusatsu Onsen (´▽`*).

If you need assistance planning your visit to Kusatsu Onsen, there is also a tourist counter at Kusatsu Onsen Bus Terminal.

  • Kusatsumachi Hot Spring Library is open from 9 am to 4:30 pm from Tuesday to Sunday. If Monday is a public holiday, it will close the next business day.
  • Nagaden Bus Ticket Counter is open from 7:45 am to 5:30 pm.

Kusatsu Confectionary Seigetsudō (草津菓匠 清月堂)

Your visit to a traditional hot spring resort is only complete with traditional confectionery. Where to get it? How about Kusatsu Confectionary Seigetsudō?

Kusatsu Confectionary Seigetsudō was opened in 1923. What is famous there is its scarlet runner bean confectionary range. The scarlet runner bean planted in Kusatsu was originally from Hokkaidō. Because of Kusatsu’s warmer climate, the scarlet runner beans harvested from the field at an altitude of more than 1,000 meters are bigger than those in Hokkaidō. The confectionery maker thus gave it a different and more elegant name, Hanaingen (花いんげん豆).

And don’t underestimate the simple sweetened bean! The Amanattō (甘納豆) was certified by the Governor of Gunma as an excellent product of the prefecture. It was also highly praised by the Japanese Emperor and other imperial family members!

Whether it is Amanattō, Yōkan (羊羹), or Monaka (最中), the traditional sweets just taste differently with scarlet runner bean. And as a Hanaingen specialist, the bean paste in their manjū buns is, of course, made from Hanaingen (with white kidney bean paste blended)!

If you want to try out the Hanaingen before purchasing more for your families and friends, get the smallest package, which contains six beans (in the case of Amanattō). If you love it, you can always purchase more (=゚ω゚)ノ.

☛ As special as Hanaingen is, we want to point out that those who don’t have a sweet tooth probably won’t find it delicious.
☛ The shelf life of Seigetsudō’s confectionary is short, with a maximum of three days in the summer and five days in the winter. Please check the dates carefully before purchasing.

Seigetsudō’s Cafe Hanaingen (清月堂 カフェ花いんげん)

Seigetsudō also has a cafe attached to its Monzen-dōri Street Shop (門前通り店) close to Yubatake. If you like tiramisu, you will fall in love with their Matcha Tiramisu (抹茶ティラミス). Unlike the typical tiramisu that is chocolate based and contains liquor, Seigetsudō’s tiramisu is made with Dorayaki sandwiched with Hanaingen and matcha flavored cream. The cake is finished with a drawing of a white onsen mark on the green-colored cream, perfect for the dessert served in Kusatsu Onsen!

What goes really well with their dessert menu is a cup of matcha tea made from premium matcha powder from Uji, Kyoto. Like Westerners enjoying a slice of cake with a cup of black tea, when you are in Japan, it is the matcha green tea you would want for afternoon tea (^_-)-☆.

Seigetsudō’s Business Hours and Access Information

  • Seigetsudō is open daily except for Tuesdays from 9 am to 5 pm.
  • Seigetsudō is just a 1-minute walk from Kusatsu Onsen Bus Terminal.
  • The cafe is open daily except for Thursdays from 9 am to 5 pm.

Shunsai Chaya Yumehana (旬彩茶屋 夢花)

It is probably just around lunchtime when you arrive at Kusatsu Onsen. So where to head for lunch?

If you don’t mind non-vegetarian dipping sauce/broth or can bring your own bottle of vegetarian sauce while traveling, head to Shunsai Chaya Yumehana just in front of the Kusatsu Onsen Bus Terminal. You can enjoy some delicious soba noodles made with almost 100% soba flour!

While most dishes on the menu aren’t vegetarian, the few dishes that you can order are the ones that have Maitake mushroom (舞茸) as the main dish. Whether it is Maitake Soba/Udon (舞茸そば・うどん) or Maitake Tempura Soba/Udon (舞茸天ぷらそば・うどん), they are recommended!

Why Maitake mushroom? Because, speaking of Gunma Prefecture‘s speciality, it has to be the Maitake mushroom (舞茸). If you really dislike mushrooms, there are also dishes with deep-fried eggplant.

For dessert, get one of the pinto bean tarts called Koyuki-Chan (花豆タルト 小雪ちゃん). Even the locals love it!

Shunsai Chaya Yumehana’s Business Hours and Access Information

  • Shunsai Chaya Yumehana is open from
    • 10 am to 3 pm
    • 5:30 pm to 9:30 pm
    • The last order is taken at 8:45 pm.
  • Shusai Chaya Yumehana is just a 2-minute walk from Kusatsu Onsen Bus Terminal.

Yubatake (湯畑)

Yubatake is Kusatsu Onsen’s landmark. The spot where more than 4,000 liter of hot springs gushes out per minute becomes like a field of hot springs, which is why the locals named it Yubatake. In addition, it is a hot spring field where sulfur can be “harvested”.

Ⓒ 草津温泉観光協会

Regarding the amount of onsen flowing out of the spring source, Yubatake at Kusatsu Onsen proudly claimed to be the highest. You probably won’t be able to find another spot in the world with such an area covered by hot springs! So remember to take a walk on the promenade around Yubatake to examine this rare scene. It will only take 15 minutes (^_-)-☆.

Refer to our article on Yubatake for more information!

Netsunoyu (熱乃湯) and the Traditional Performance Yumomi (湯もみ)

If this is your first time visiting Kusatsu Onsen, the attraction that you have to visit is Netsunoyu (熱乃湯). Why? Because it is where the hot spring town’s iconic show, Yumomi, is held! It is one of the main reasons why tourists visit Kusatsu Onsen.

Yumomi is the name given to the process of stirring high-temperature hot spring water with large wooden paddles. This is a part of the hospitality of Kusatsu Onsen’s bathhouses to bring down the hot spring’s temperature without diluting it with cold water. That way, the customers can enjoy the full medical benefits of Kusatsu’s hot spring!

Ⓒ 草津温泉観光協会

For more information about Yumomi and other performances at Netsunoyu, refer to our Guide to Netsunoyu and Kusatsu Onsen’s Iconic Show – Yumomi!

Honke Chichiya (本家ちちや)

One of the must-buy souvenirs in any hot spring town is Onsen Manjū, a traditional bean-paste bun. A recommended Onsen Manjū shop is Chichiya for the freshly made Onsen Manjū. Unlike many manjū makers, Chichiya makes their manjūs when the stock level is low, so you are guaranteed that the buns handed to you are freshly made!

The popular Manjū here is White Nishikian Manjū (二色あんまんじゅう(白)). Unlike the usual Manjū that only has one type of bean paste wrapped, the white Nishikian Manjū has both chestnut and smooth red bean paste. Because of the different colors of the chestnut and red bean paste, the shop named it Nishiki, which means two-colored.

If you prefer a simpler taste, get the brown-colored Cha Manjū. The brown color came from the black sugar used to sweeten the bun’s skin. Inside the bun is the mashed red bean paste.

So what is the texture of the buns? The skin of the buns is fluffy. Unlike many traditional desserts sold in Japan, the manjū’s filling isn’t too sweet. So you can have it on its own or with a cup of tea or coffee!

Another confectionary that you might want to give a try is Chichiya Baum (ちちやバウム). It has a texture similar to a castella cake!

Honke Chichiya’s Business Hours and Access Information

  • Chichiya is open from 8 am to 6 pm.
  • Chichiya is just a 2-minute walk from Kusatsu Onsen Bus Terminal.

Tip: If the buns are sold out at the main store, you can visit the other two stores in Kusatsu Onsen to try your luck.

Kōsenji Temple (光泉寺)

A religious spot you have to visit when you are in Kusatsu Onsen is Kōsenji Temple. Even if you aren’t interested in visiting a temple, you can still get a wide view of Kusatsu Onsen’s township from the temple’s gate atop the staircases behind the communal bathhouse, Shirahata no Yu (白旗の湯)!

In addition, together with Arima Onsen‘s Onsenji in Kobe and Yamanaka Onsen‘s Iōji in Ishikawa Prefecture, they are also known as Japan’s Top Three Hot Spring Healing Buddha Temples (日本三大温泉薬師).

Kōsenji was erected in 721 by Gyōki (行基), the highly-regarded monk in the Nara period who contributed greatly to Nara‘s Todaiji’s Great Buddha!

For more information, refer to our article on Kōsenji (=゚ω゚)ノ.

Yubatake Souan Foot Spa Cafe (湯畑草菴 足湯カフェ)

If you are after a place for something unique and different, how about stopping by Yubatake Souan? The cafe in this hot spring hotel is quite interesting. In addition to the regular table sets, the foot spa cafe also has seats around a foot spa as well as a hand spa!

While the cafe doesn’t serve vegetarian savory light meals, you can still enjoy afternoon tea at Yubatake Souan Foot Spa Cafe. The recommended dessert menu items are those with pinto beans. Why? Because pinto bean is one of Kusatsu’s local specialties!

☛ There are coin lockers available for customers to use.
☛ The best time to visit Yubatake Souan Foot Spa Cafe for couples is probably at night. With the lighting illuminating the foot spa, the atmosphere is beautiful and somewhat romantic!

Yubatake Souan Foot Spa Cafe’s Business Hours and Access Information

  • Yubatake Souan Foot Spa Cafe is open from 10 am to 9:30 pm.
    • The last order is taken at 9 pm.
  • Yubatake Souan Foot Spa Cafe is just a 5-minute walk from Kusatsu Onsen Bus Terminal.

Shirane Shrine (白根神社)

Ⓒ photo-ac.com

If you are after some peace and quietness during your time at Kusatsu Onsen, Shirane Shrine (白根神社) north of Yubatake could be the spot you would want to visit. Especially from late April to early May, the shrine is where you can adore the gorgeous flowers of Rhododendrons (=゚ω゚)ノ.

For more information about the shrine, refer to our article on Shirane Shrine!

Grandefiume KUSATSU (グランデフューメ草津)

If you love Italian gelato and rusk, stop by Grandefiume KUSATSU. The shop mainly specializes in rusks. With more than 10 flavors of rusks on the shelf, it is hard to decide which flavor to bring home! ヾ(≧▽≦)ノ.

The best thing about the shop is the all-you-can-eat gelato which only costs 880 yen (440 yen for children)! In addition to the gelato, the cost also includes unlimited rusks and sauce. As long as the shop isn’t packed, there won’t be any time constraints! There is even a small drinks bar where you can make yourself a cup of tea or coffee (=゚ω゚)ノ.

After you pay at the register and secure your seat on the second or third floor, you can head to the gelato machine before adding toppings from the bar counter.

But just note there are only four flavors for gelato: vanilla, chocolate, yogurt, and a seasonal flavor.

☛ Be careful with the gelato machine. A small pull on the lever can bring you a lot of gelato! Taking a small amount at a time is wiser if you want to try different flavors and toppings.
☛ As delicious as it is, overeating gelato at once can give you a stomachache. As there is no time limit, we recommend you take it slow and warm yourself up with a cup of tea.

Grandefiume KUSATSU’s Business Hours and Access Information

  • Grandefiume KUSATSU is open from 10 am to 5 pm.
  • Grandefiume KUSATSU, located at the front of the public bathhouse, Ohtaki no Yu (大滝乃湯), is around a 5 to 10-minute walk from Kusatsu Onsen Bus Terminal.

Kusatsu Mori no Iyashi Hodō Promenade (草津森の癒し歩道)

If you love trekking, there are three trekking courses adjacent to Kusatsu Onsen for you to enjoy. These courses were originally the logging roads in the national forest. But in 2001, the area was opened to the general public.

  • Royal Course (ロイヤルコース)
    • 1.3km, suitable for everyone
    • The promenade is covered by red pine wood chips.
    • Visited by the Heisei Emperor and Empress, which is why the course was named the Royal Course

Tip: Check with Hotel Village to see if they still hold Royal Course trekking tours for their guests.

Sainokawara Park (西の河原公園)

Kusatsu Onsen is located at a high altitude of about 1,200 meters, so the fall foliage season would come earlier than in many parts of the Kantō Region. If you happen to visit Kusatsu Onsen in November, Sainokawara Park (西の河原公園) is one of the top spots to adore the autumn color! In fact, Sainokawara Park is a place you would want to visit any time of the year!

Throughout the year, the park is illuminated after sunset. When the weather becomes more chilled, free foot spas in the park can help keep you warm!

Kusatsu Forest Stage (草津フォレストステージ)

The courses are divided into Fairy Stage (フェアリーステージ) and Master Stage (マスターステージ). The Fairy Stage obstacles are for anyone weighing less than 130 kg, not just for families. In this zone, the obstacles are easier and may be suitable for anyone seven years old and older. The zip line is probably the most popular attraction as you will be flying above a sightseeing bus if it happens to drive past the park!

Ⓒ 草津温泉観光協会

Dr Erwin visited Kusatsu in 1878. Astonished by the medical effects of the hot spring there, he introduced Kusatsu Onsen to the world as a world-class hot spring resort. The museum was built to appreciate his effort in bringing Kusatsu to the world’s attention. This is also why a road in Kusatsu Onsen was named after him. You will also find a statue of Dr Erwin in Sainokawara Park.

While English notation isn’t provided to all the exhibits in the museum, there are some old photos of Kusatsu Onsen that you may be interested in. It is free to enter, so it won’t hurt to spend a couple of minutes inside Baelz Museum (^_-)-☆.

Ⓒ photo-ac.com

After visiting Kusatsu Onsen, you can drive up to Shiga Kōgen. The 43km-long scenic freeway connecting the two popular destinations is National Highway No. 292, known as Shiga Kusatsu Kōgen Route. The route goes as far as Shibu Onsen (渋温泉郷) in Nagano Prefecture, close to the Jigokudani Snow Monkey Park.

Regardless of the season, the view you will get at the highest point of the Japanese National Highway, Shibu Tōge Pass (渋峠), at an altitude of 2,172 meters, will be magnificent!

Ⓒ 草津温泉観光協会

Yunohana Collection Activity (湯の花採取体験)

An interesting activity you can do at Kusatsu Onsen is the Yunohana Collection Activity.

What is Yunohana? It is crystalized hot spring. While you can purchase the dried Yunohana from souvenir shops, if the Yunohana Collection event is on during your visit, we highly recommend that you participate in it as it is the only time of the year when you are allowed to enter Yubatake at the center of the hot spring town!

It is said that only around 7,000 Yunohana crystals can be produced each year. So if you miss out on the grand event in autumn, how about getting a bottle of Yunohana from one of the shops in Kusatsu Onsen for your families or friends because it is so precious?

Note that the event is usually held on a first-come-first-serve basis, with only the first 20 to 30 people being allowed to participate.

Kamakuraito (かまくらいと)

From mid-January to February, many igloos are set up around Yubatake. Inside the illuminated igloos, you will find dioramas related to Kusatsu. So if you want to know more about Kusatsu Onsen’s history and culture, visit Kusatsu Onsen at the beginning of the year!

Discover Shima Onsen, Another Famous Hot Spring Town in Gunma Prefecture
