5 Onsen Towns in Tohoku That Still Feel Like Secrets

Japan has over three thousand distinct hot spring areas. Most travellers visit the same ten. The Tohoku region contains several dozen that meet every criterion for a world-class onsen experience — mineral content, ryokan quality, surrounding landscape, historical depth — while remaining unknown to the international market. This is either a mystery or an opportunity. We prefer the latter.

1. Nyuto Onsen — The Deep Forest Cluster

Seven inns, each with its own spring, spread through the beech forests above Lake Tazawa in Akita Prefecture. The most famous is Tsurunoyu, operating since the 1600s, where the milky white water flows into thatched-roof outdoor baths with views of forested slopes. The dirt road that leads to Tsurunoyu closes in winter, replaced by a shuttle bus that somehow makes the arrival feel even more deliberate. Stay at least one night. In winter, this may be the most beautiful place in Japan.

2. Naruko Onsen — Five Springs, One Valley

The Naruko gorge in northern Miyagi Prefecture contains five distinct types of hot spring water — the most variety in any single area of Japan. The town is also the traditional home of the Naruko kokeshi doll, a painted wooden toy with a characteristically large head that has been made here for 150 years. Small workshops still produce them by hand. The onsen water varies from milky white sodium bicarbonate springs to clear, sulphurous pools. A serious visitor will try all five types.

3. Hanamaki Onsen — Where the Poet Soaked

Hanamaki in Iwate Prefecture was the birthplace and lifetime home of Miyazawa Kenji, the poet and author whose work inspired Hayao Miyazaki and whose humanist philosophy — known as "being a person of the world" — continues to shape Japanese environmental thought. The onsen area outside town is where he walked and wrote. Several ryokan maintain the unhurried, literary quality of the surroundings. The Hanamaki area also produces some of Iwate's finest sake.

4. Higashiyama Onsen — Aizu's Quiet Cousin

Thirty minutes east of Aizuwakamatsu — the samurai castle town of Fukushima Prefecture — Higashiyama Onsen sits in a river valley lined with traditional ryokan. It receives a fraction of the visitors that go to Aizuwakamatsu itself, despite being directly connected by bus. The water is simple sodium chloride; the surroundings are quiet mountains; the ryokan are run by families who have been operating them for three or four generations. This is the Tohoku onsen experience in its most unadorned form.

5. Sukayu Onsen — The Communal Bath of History

At the upper end of the Oirase Gorge in Aomori, Sukayu Onsen's Sen-nin-buro — the Bath of a Thousand People — is a single enormous wooden hall where multiple pools of different temperatures share the same steam-filled space. The bath has been mixed-gender for its entire history of over three hundred years. Bathing here requires a willingness to leave self-consciousness at the entrance. What you receive in exchange: a direct connection to how Japan has always understood the relationship between community and water.
