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 pit dwelling sites have been discovered in the Lake Tazawa area, indicating that people engaged in hunting and farming have lived there since ancient times. In the Edo period, in 1602, the Satake clan, who were transferred from Hitachi (present-day Ibaraki Prefecture) to Akita, came to rule the six counties of Akita, and a checkpoint was established in Obonai, on the border between the Nanbu and Akita domains. In the 18th century, land reclamation progressed, utilizing the waters of Lake Tazawa, and forestry reforms were also implemented. Furthermore, the area developed into a horse breeding region renowned throughout Japan. With the implementation of the municipal system in 1889, Obonai Village, Tazawa Village, and Jindai Village were established. In 1940, highly acidic water from the Tamagawa River was introduced into Lake Tazawa for power development and agricultural land reclamation, causing the death of fish such as the kunimasu, which is considered an endemic species of Lake Tazawa. However, thanks to the neutralization treatment of the acidic water, fish can now be seen again. In September 1956, the three towns and villages of Obonai (which became a town in 1953), Tazawa Village, and Jindai Village merged to form "Tazawako Town," which remains 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.
