Tazawa

Tazawa is a toponym most commonly associated with Lake Tazawa (Tazawa-ko) in Akita Prefecture, Japan. Lake Tazawa is a crater lake located in the northern part of Akita, within the municipality of Semboku. It is widely recognized as the deepest lake in Japan, with a maximum depth reported around 423 meters. The lake’s waters are fed primarily by springs, and it lies near the Nyuto Onsen hot spring area, making it a popular destination in the region.

The name Tazawa derives from the Japanese kanji characters for “rice field” (田) and “swamp” or “marsh” (沢/澤), reflecting historical agrarian land use in the area. The term is used in local place names beyond the lake, including the surrounding district and facilities that bear the name.

In addition to Lake Tazawa, Tazawa as a toponym may be encountered in local geography within Akita Prefecture. The lake and its surroundings form part of a broader natural and cultural landscape that includes seasonal tourism, hot springs, and views of the surrounding mountains.

Notable features associated with Tazawa include its status as Japan’s deepest lake and its scenic setting in a volcanic region of the Tohoku region. The area is frequently promoted for sightseeing, outdoor recreation, and autumn foliage, contributing to the local economy and cultural identity.
