Overview
Tsuta Onsen is one of Aomori Prefecture's most historic hot springs, with a history said to span a thousand years. Surrounded by a vast primeval beech forest known as the Towada Jukai, the single inn, Tsuta Onsen Ryokan, continues to preserve its legacy. The area once flourished as a therapeutic spa and is also famous as the place beloved by Meiji-era writer Keigetsu Omachi, who spent his final years here.
Its most distinctive feature is that the spring water gushes directly from between the wooden floorboards of the bathtub, a style known as "gensen-kakenagashi." This allows you to soak in fresh, pure hot spring water that has not been altered by adding water, heating, or circulation. The bathhouse, made of beech wood, has a rustic charm, and listening to the birdsong and rustling trees in the silence creates a feeling of becoming one with nature.
Primary Spring Quality and Indications
The water at Tsuta Onsen is classified as a Sodium/Calcium - Sulfate, Bicarbonate, Chloride Spring. While this indicates a good balance of minerals, it is particularly known for its properties as a Sulfate spring. This type of water is said to moisturize and protect the skin, earning it the name "Bihada-no-yu" (water for beautiful skin). It also helps to improve blood circulation and warm the body from the core.

Water Characteristics and Best Season to Visit
The water, welling up directly from the bottom of the tub, is incredibly fresh as it has minimal contact with the air. The source temperature is around 45°C (113°F), which is slightly hot, but the water is clear and feels very soft on the skin. The spring is also voluminous, constantly replenishing the tubs. Onsen where you can experience this rare "ashimoto-yushutsu" (gushing from the feet) style are few and far between in Japan.
The best times to visit are from late May to June, when the new green leaves of the beech trees are vibrant, and from mid to late October, when the forest is ablaze with autumn colors. The morning glow over the nearby Tsuta-numa Pond is especially famous. Winter is a heavy-snow season, so access requires caution, but a quiet snow-viewing bath is a special experience.
