Conclusion

Takaragawa Onsen locates in Gunma prefecture, which is well known as of the nation’s biggest onsen, or hot spring prefectures. Although it is lesser known compared to onsen such as Kusatsu or Ikaho, it is slowly gaining attention for its rejuvenating waters and amazing views.

The baths at Takaragawa Onsen have even been featured in famous guidebooks as one of the top ten hot springs in Japan. The hot springs aren’t too far from Tokyo, and make a great day-trip destination.

About Takaragawa Onsen

Takaragawa Onsen is surrounded by lush nature, and is a part of the Mizukami Onsen Resort in Gunma prefecture’s Tone district.

The waters of the baths are all directly from the springs. Every minute, the springs spout out about 1,800 liters of water.

Takaragawa Onsen began gaining attention after receiving the title of “Best Riverside Onsen” on Lonely Planet’s “Top 10 hot springs in Japan” list.

The baths were also used as a filming location for the hit film, “Thermae Romae II”. Through the growing media coverage, Takaragawa Onsen has gained further recognition in recent years.

Takaragawa Onsen’s soaring popularity

One of the main factors of Takaragawa Onsen’s skyrocketing popularity can be attributed to its huge rotemburo, or outdoor baths, that are surrounded in nature.

There are four rotemburo at Takaragawa Onsen. Three are co-ed, and one is women only. They are some of the largest outdoor baths in japan.

Altogether, the baths measure around 900 meters squared, making it one of the biggest in Japan. Its spaciousness and breathtaking views of nature make it a popular hot springs destination.

Osenkaku and Takaragawa Sanso

The two facilities you can use to bathe in the Takaragawa Onsen waters are Osenkaku and Takaragawa Sanso.

Osenkaku is for guests who are staying, and Takaragawa Sanso is for day-trip visitors.

At Osenkaku, you get to choose from a variety of yukata to wear during your stay.

The 4 rotemburo

The four rotemburo (outdoor baths) measure about 900 meters squared combined. The baths are located right by the Takaragawa River.

When switching between baths, you don’t necessarily have to change in and out of your clothes. You can just keep yourself covered with a towel as you navigate between baths.

Maka Bath

The Maka Bath is the most popular bath out of the four rotemburo. The bath measures about 220 meters squared.

The bath was completed in 1940, and served as a model for upcoming rotemburo baths.

Autumn and winter are exceptionally beautiful at the Maka bath. In the autumn, maples surround the bath, and in the winter, the area is covered in snow.

The Hannya Bath is a bit more modest-sized compared to the other three rotemburo. It is about half the size of the Maka Bath.

The waters of this bath are shallow, so this is a good choice if you are bathing with children.

Maya Bath

The Maya Bath is the one women-only bath out of the rotemburo. It locates at the lower part of Takaragawa River, and is not surrounded by any fences but only by nature.

Bathing in a co-ed bath

If co-ed baths sound kind of intimidating, don’t worry. Even most Japanese people haven’t been in a co-ed bath. Takaragawa Onsen provides women’s bathing clothes (for overnight guests) and towels (for day-trip guests) for those who want to cover up.
