Written by :  GOOD LUCK TRIP

One of Japan’s Three Legendary Hot Springs, “Kusatsu Onsen,” is a hot spring town with a long history, beloved by shoguns and other great figures since ancient times.
It’s famed as “Japan’s finest hot spring,” with outstanding healing benefits—so much so that there’s a saying, “There’s no illness it can’t cure—except lovesickness.”
The appeal of “Kusatsu Onsen” is that you can experience “healing” by soaking in the baths, “fun” by discovering traditional culture, and the “joy” of tasting local specialty food—all at once.
In this article, we’ll introduce the charms of the hot springs and recommended spots so even first-time visitors to “Kusatsu Onsen” can enjoy sightseeing.

What is Kusatsu Onsen Like?

Located at the foot of Mount Kusatsu-Shirane in Agatsuma District, Gunma Prefecture, “Kusatsu Onsen” is one of Japan’s leading hot spring destinations and is counted among Japan’s Three Legendary Hot Springs.
It has a long history and is said to have been loved by many notable figures and even characters from myths, including Tokugawa Ieyasu, the first shogun of the Edo shogunate, and Tokugawa Yoshimune, the eighth shogun.
A key feature of “Kusatsu Onsen” is its sulfur-rich, high-temperature water—nearly 122°F (50°C)—and it’s famous as “Japan’s finest hot spring,” with such strong healing benefits that there’s a saying, “There’s no illness it can’t cure—except lovesickness.”
With a natural flow of at least 85,300 gallons (323,000 liters) per minute—the highest in Japan—you can fully enjoy its mainly six different source springs. Another highlight is that you can also visit for a day trip.
Beyond the baths, you’ll find plenty to enjoy, including local street food, traditional culture, and hands-on experiences like authentic shooting.
Yubatake, located in the center of “Kusatsu Onsen,” is an iconic symbol that visitors should absolutely see.
With steam rising all day long, you’ll truly feel you’ve arrived at a hot spring town—and the sight of 1,057 gallons (4,000 liters) of spring water gushing up per minute is sure to impress.
At sunset, the area is illuminated, letting you enjoy a different side of the town by day and by night.
The traditional Yumomi Show is another must-see, where you can watch the technique of cooling the extremely hot spring water by stirring it with wooden paddles.
At Sainokawara Park, where rugged nature remains, hot spring water bubbles up all around. Along with free footbaths, we also recommend strolling to enjoy the mountain stream and waterfalls.

What’s the Best Season to Visit Kusatsu Onsen?

If you’re visiting “Kusatsu Onsen,” winter is recommended.
Kusatsu’s climate is mild, but as early as November, snow begins to fall and the surrounding area turns white.
Take in a dreamlike world you can only see here, with billowing steam rising from snowy scenery and icicles formed by the cold.
There are also ski resorts nearby, so you can enjoy winter sports, too.
After a full day of sightseeing, soak in the hot springs and relax as you warm up your body chilled by the harsh cold.

3 Ways to Enjoy the Unique Charms of Kusatsu Onsen

The appeal of “Kusatsu Onsen” goes beyond hot springs.
From enjoying the nostalgic onsen town while sampling local specialties to experiencing traditional Japanese culture, there are many ways to have fun.
Among the many highlights of “Kusatsu Onsen,” here are three can’t-miss picks.

1. Street food in a charming onsen town

“Kusatsu Onsen” is full of local specialties and has many tempting shops.
Here, we’ll introduce two: “Yubatake soba” and “pork shabu-shabu.”
Yubatake soba, made with hot spring water, is known for its firm, smooth texture—and it’s outstanding with local maitake mushroom tempura.
Gunma’s specialty pork shabu-shabu enjoyed with soba-yu (buckwheat broth) is also recommended as a Kusatsu-only local favorite.
And be sure to enjoy eating as you stroll through the town streets.
For example, the classic onsen manju (hot spring buns), a popular souvenir, varies by shop in its craft and character, making it fun to compare.
The mellow “Kusatsu Onsen pudding” and the nostalgic “Yukemuri cider” also come in thoughtfully designed packaging—perfect as a trip memory.

2. Experience Kusatsu Onsen’s unique culture

Experiencing traditional Japanese culture is also one way to enjoy “Kusatsu Onsen.”
Two especially popular options are the “Yumomi Show” and “Kusatsu Onsen rakugo.”
Yumomi is a Japanese tradition that dates back to the Edo period (1603–1868), created as a way to lower the high temperature of the source water without adding water (so the benefits aren’t reduced).
You’ll be amazed watching performers stir the water with long wooden boards to the tune of the famous folk song “Yumomi-uta,” which begins with “Kusatsu yoi toko ichido wa oide.”
Now a beloved new Kusatsu specialty, “Kusatsu Onsen rakugo” starts at 8:00 pm every day, 365 days a year, letting you end your day with a relaxed performance of traditional storytelling.
The stage is the same venue as the “Yumomi Show,” with its distinctive atmosphere, and most visitors are first-time rakugo listeners—so don’t worry.
There are also many facilities around Kusatsu Onsen where you can experience Japan in unique ways, so be sure to try them firsthand.

3. Enjoy different baths with an onsen-hopping tour

Onsen hopping in a yukata might just be the biggest charm of “Kusatsu Onsen.”
Onsen hopping means visiting day-use bath facilities (public bathhouses) to enjoy different hot springs.
Strolling through the atmospheric onsen town while enjoying baths with different benefits and styles is a true highlight of a Kusatsu Onsen trip.
With a yukata rental service, you can wear one even without staying overnight, and there are plenty of styles—so pick your favorite.
“Kusatsu Onsen” has many public baths, so we hope you’ll visit the ones introduced next.

3 Day-Use Hot Spring Facilities Where You Can Enjoy Kusatsu’s Traditions and Nature

Here are three day-use hot spring facilities where you can soak in precious source water while enjoying Kusatsu’s traditions and nature.
If you want to enter all three facilities, we recommend buying the “Choina Sanyu Meguri Tegata” pass.
It saves you around 500 yen compared to paying separately, and if you visit all of them, you’ll receive a “Kanto Ninteisho” certificate that also doubles as a postcard.

1. Gozanoyu

“Gozanoyu” recreates a public bathhouse from the Edo to Meiji era, and the carefully crafted wooden exterior and tradition-respecting interior are truly moving.
It features two different bathing areas—“Kino-yu” and “Ishi-no-yu” (men and women alternate daily)—and the big draw is enjoying two source waters at once: the sharp “Yubatake source” and the gentle “Bandai source.”
If you compare them, you should be able to feel the difference on your skin.
Main benefits include neuralgia, beautiful skin, and bruises.
On the second floor, there’s a large tatami-floored rest hall (Yugen-no-ma) where you can relax, and the spectacular view of Yubatake from here is also a must-see.

2. Sainokawara Rotenburo

“Sainokawara Rotenburo” is proud of its open-air bath, one of the largest in Japan.
Its biggest appeal is the open feeling, with 360-degree views of Kusatsu’s rich nature, and you can enjoy different scenery each season, like fresh spring greenery, autumn leaves, and winter snow.
It uses the same “Bandai source” as “Gozanoyu,” and benefits are expected for neuralgia, bruises, and chronic digestive disorders.
It also underwent its first major renovation since opening in 2015, which is a nice bonus as the facility is clean.

3. Otakinoyu

The largest day-use bathing facility, “Otakinoyu,” lets you soak in the precious “Nikawa source,” which isn’t used by other hotels and ryokan.
The “Nikawa source” is known for its very high temperature and clear water with little cloudiness. Famous as a “beauty bath,” it’s said to help with neuralgia, sprains, and burns.
At “Otakinoyu,” a key attraction is experiencing Kusatsu’s traditional “Awaseyu,” where you enter baths from lower temperatures in order.
With a spacious layout and many washing stations, it’s recommended for those who want to take their time.
It’s also the only day-use bathing facility with a restaurant, making it perfect for wrapping up your sightseeing.

3 Public Bathhouses in Kusatsu Onsen Where Tourists Can Bathe

Public bathhouses are hot spring facilities managed and operated by local residents, and many were originally created mainly for locals to use.
“Kusatsu Onsen” has 19 public bathhouses, and three of them can be used by tourists as well.
All of them are free, but be sure to follow proper etiquette and remember you’re borrowing a bathhouse used by local residents.

1. Shirahata-no-yu

Located just near “Yubatake,” “Shirahata-no-yu” is a representative public bathhouse, with a legend that Minamoto no Yoritomo discovered it.
It features rare, hot, milky-white water—unusual even within “Kusatsu Onsen”—and you’ll often see plenty of yunohana (mineral deposits).
This cloudy water contains a lot of sulfur and is said to help with skin conditions, insomnia, and joint pain.
“Shirahata-no-yu” is the largest public bathhouse (capacity: 4–5 people) and is relatively easy to try, so it’s recommended for beginners.

2. Chiyo-no-yu

Built from wood and full of old-fashioned charm, “Chiyo-no-yu” is a small public bathhouse with a capacity of around three people.
Because the tub is small, the water is always fresh, and compared to other bathhouses, the sulfur scent is softer and feels pleasant.
At “Chiyo-no-yu,” we recommend trying Kusatsu’s traditional therapeutic bathing method, “Dentoyu (Jikan-yu).”
“Dentoyu” refers to a sequence like this: “yumomi → pour around 10 bowls of water over your feet → pour around 30 bowls over your head → bathe for 3 minutes at the leader’s command → rest.”
It’s said to have benefits such as promoting health, easing muscle pain, and relieving joint pain.

3. Jizo-no-yu

“Jizo-no-yu,” renovated in 2022, is a hidden-gem public bathhouse that blends newness with atmosphere.
It features slightly milky water called “Jizo source,” and with its high ceiling, the breeze blowing in from outside feels refreshing.
It’s been said since long ago to help with eye conditions, and the “Mearai Jizo” statue also stands nearby.
It also has footbaths, handbaths, and a facial bath, so even those without time for a full soak can easily experience “Jizo-no-yu.”
Relatively rare nationwide and unique to “Kusatsu Onsen,” the facial bath is popular for feeling great and benefiting your eyes and skin.

Choosing a hotel is also important—it’s your sightseeing base and a place to relax and unwind.
There are many accommodations, from historic long-established hotels to resort hotels, but here are three recommended hotels where you can enjoy precious source water.

2. Hotel Sakurai

“Hotel Sakurai,” on a hill in the center of Kusatsu Onsen, is a hot spring inn known for being one of the largest in Kusatsu.
It’s proud of its baths supplied by three sources: in the large public bath—one of the biggest in Kusatsu Onsen at 98 feet (30 m) long—you can enjoy a blended spring of “Sainokawara source” and “Bandai-ko source,” while the open-air bath also includes “Wata-no-yu source,” letting you soak in 100% natural source water without added water from all three.
The festival plaza inside the building is a lively entertainment space.
Every day, they hold two event shows: Kusatsu Onsen’s traditional “Yumomi,” which you can join in on, and the powerful “Sakura Taiko” drum performance.

3. La Vista Kusatsu Hills

La Vista Kusatsu Hills opened in 2021 on the hills of Kusatsu Onsen.
In an atmosphere reminiscent of an elegant Western-style mansion, this resort hotel lets you enjoy views worthy of the name “La Vista (view),” including Kusatsu Onsen’s first top-floor bath facility at an onsen inn.

The hot springs use water drawn from three sources: Yubatake source, Bandai-ko source, and Yukawa source.
In addition to the top-floor scenic bath with open-air and indoor baths plus barrel baths, you can also look out over a grand panorama of Kusatsu’s mountains and the onsen town from four different private open-air baths, each with a different style, such as rock and ceramic.

Because it’s located near Kusatsu Onsen, it’s also long been famous as “Kusatsu’s finishing bath.”
This name came from the tradition of bathing in Kusatsu’s strongly acidic waters for hot spring therapy, then soaking in Shima Onsen’s sulfate springs—known for moisturizing and brightening effects—to complete the regimen.
