Tazawako
TazawakoTazawako, with its deep blue surface and the legend of Princess Tatsuko, is an almost circular lake with a circumference of about 20 kilometer
Numerous stone tools, pottery, and remains of pit dwellings have been discovered around Lake Tazawa, indicating that the area has been inhabited by hunters and farmers since ancient times. In the Edo period, in 1602, the Satake clan, who were transferred from Hitachi (present-day Ibaraki Prefecture) to Akita, acquired control of the six districts of Akita. A checkpoint was established in Ibonai, on the border between the Nanbu and Akita domains. In the 18th century, new land reclamation progressed, utilizing Lake Tazawa's waters, and forestry reforms were implemented. The area also developed into a nationally renowned horse breeding region. With the implementation of the city and town system in 1889, the villages of Ibonai, Tazawa, and Jindai were established. In 1940, highly acidic water from the Tamagawa River was introduced into Lake Tazawa for power generation and farmland development, resulting in the extinction of endemic fish species, such as the kunimasu salmon. However, due to a treatment project to neutralize the acidic water, fish can now be seen. In September 1956, the towns of Ikuhonai (established as a town in 1953), Tazawa Village, and Jindai Village merged to form Tazawako Town, which remains the same to this day.
About Lake Tazawa
Lake Tazawa is an almost perfectly round lake with a circumference of 20 km, an area of 25.5 km², and a depth of 423.4 m—making it the deepest lake in Japan.
Its waters are a mysterious and beautiful sapphire blue, perfectly befitting the legend of Princess Tatsuko.
Each season brings its own charm:
In spring, soft light shimmers on the surface of the lake.
In summer, deep green forests and blue skies surround the water.
In autumn, colorful foliage reflects vividly on the lake.
In winter, the contrast between the pure white snow and the lake’s surface is striking.
The sunrise and sunset are also spectacular.
On calm mornings especially, the lake becomes mirror-like, brilliantly reflecting the morning sun.
