Tamagawa Onsen Travel Tips

2 of 7 in Akita Prefecture

Tamagawa Onsen (玉川温泉), located in the picturesque mountains of Towada-Hachimantai National Park, is renowned for Japan's most acidic hot spring waters, with a nearly pH 1 level. This unique onsen also features hokutolite, a rare radioactive stone believed to offer health benefits, including possible cancer prevention. These qualities draw many visitors seeking its potential healing properties, while traditional onsen guests enjoy the natural beauty and relaxing atmosphere.

The resort is centered around a single ryokan offering simple rooms and a public bath, welcoming both overnight and day guests. Although primarily frequented by health-focused visitors, regular tourists are welcome to experience Tamagawa Onsen's distinct mineral-rich waters. The ryokan closes during winter, from early November to mid-April, due to snow.

Getting there

Tamagawa Onsen is accessible by local buses or car from both the north and south. In winter (late November to mid-April), only the southern route remains open.

From Tazawako Station and Lake Tazawa, outside of winter, direct buses run to Tamagawa Onsen every 1-2 hours (80 minutes, 1490 yen). In winter, buses only go to Shin-Tamagawa Onsen, with limited service. Cars can’t reach the onsen from late November to mid-April, so park at Lake Tazawa and take a bus. The rest of the year, you can drive in about an hour from Tazawako Station.

From Kazuno-Hanawa Station (closed in winter), a bus runs to Tamagawa Onsen from mid-April to mid-October, but not in 2023. In winter, the road to Tamagawa Onsen is closed.
