Lake Towada - History

History

Lake Towada occupies the caldera of an active volcano, with large scale volcanic eruptions occurring approximately 55,000, 25,000 and 13,000 years ago. The most recent eruption left traces of pyroclastic flows as far away as the modern city of Aomori. The lake is a double caldera in that the inlet between its two peninsulas (called the “Nakaumi”) is the remnant of a secondary caldera which erupted and collapsed approximately 5400 years ago. The mountain continued to erupt well into the historical period, with the last recorded eruption occurring in 915 AD, devastating the surrounding area with pyroclastic flows, and covering most of the Tōhoku region of Japan with volcanic ash, leading to crop failures, climate change and famines.

The area around Lake Towada remained largely wilderness until towards the end of the Edo period, when the Nambu clan of Morioka Domain attempted large scale land reclamation projects at Sanbongihara (modern Towada) using the Oirase River for irrigation. In 1903, largely through the efforts of Wainai Sadayuki, princess trout were introduced into Lake Towada. The lake now also has rainbow trout, cherry salmon, carp, Carassius, Japanese eel. The surrounding forests are temperature deciduous, and are primarily Erman’s birch and Siebold’s beech.

The lake was selected by by the Tokyo Nichi Nichi Shimbun and Osaka Mainichi Shimbun. as one of the Eight Scenic Views of Japan in 1927. In 1936, the lake and surrounding areas became part of Towada National Park.

In 1953, in order to popularize the lake and the park, a sculpture of two women titled “The Maiden Statue” by Kōtarō Takamura was dedicated at the lakeshore as part of the park's 15th anniversary celebration. It was the last work by that noted sculptor.
