Kusatsu Onsen is a hot spring resort in Gunma, accessible in around three to four hours from Tokyo. It is ranked as one of the top three hot springs in Japan due to its high water quality and history. Learn more about the natural hot springs, food, souvenirs, and where to stay here.

Traveling in Kusatsu Onsen

Kusatsu Onsen is a hot spring district in Gunma Prefecture, located about three to four hours by bus from Tokyo. The amount of natural hot spring water flowing at Kusatsu Onsen is the most in Japan. (*1) Kusatsu is known for its high quality, free-flowing springs that are thought to warm the body and help kill bacteria.

Kusatsu Onsen

There are many restaurants and eateries in Kusatsu Onsen, making the area lively even at night. Hot springs flow from the waterfall-like Yubatake (pictured above) in the town center, where visitors can see the large amounts of steam rising.

In addition to Yubatake, there are five other spring sources: Shirahata, Bandaiko, Sainokawara, Nigawa, and Jizo.

The spring quality differs depending on its source. For example, water from Yubatake is gentle on the skin, while the water from Shirahata is cloudy. Therefore, it is recommended to go hot spring hopping to experience the different water.

Kusatsu has a hot spring cooling method called yumomi, which you can watch or even try for yourself. With so much to do, the town is almost like a hot spring theme park.

This article introduces highlights, food, and accommodations in Kusatsu Onsen needed for a great trip.

The summer temperatures are very temperate, with the hottest days reaching around just around 20 degrees.
