Akioh Lake 'Submerged Forest'
At 'Kyukamura Nyuto Onsenkyo (Address: 2-1 Tazawako Komagatake, Semboku City, Akita Prefecture; Manager: Naoya Hiratai), a resort that thrills with nature, located in Towada-Hachimantai National Park, the 'submerged forest' appears in Akioh Lake in the city around mid-May, offering a mystical view of young leaves emerging from the cobalt blue lake surface. The 'Hachimantai Aspite Line,' a sky-high mountain road spanning Akita and Iwate prefectures, which was closed by snow, has also opened. Spring has finally arrived in Akita. At Kyukamura's proud hot springs, we recommend 'hot spring hopping' among the seven inns of Nyuto Onsenkyo while enjoying the fresh greenery unique to this season.
◆ Akioh Lake's 'Submerged Forest' Spreading Downstream from Tamagawa Dam
Along National Route 341 in the local area (Yoroibata Dam, Tamagawa Dam, Semboku City, Akita Prefecture), the 'submerged forest' can be seen annually from mid-May to mid-June. The submerged forest appears when deep green trees are submerged by the lake surface, which rises due to snowmelt, and then reappears when the water level drops due to discharge during the rice planting season. The sight of the fresh green 'submerged forest' floating on the unique 'blue' water surface of the Tamagawa water system is mystical. (50 minutes by car from Kyukamura)
Large-scale renovation work is planned for the Yoroibata Power Plant from March 2027 to March 2032, during which time the submerged forest will not be visible. This is the last chance to view the submerged forest before the construction!
Location: Yoroibata, Tazawako, Semboku City, Akita Prefecture
* Since there is no parking near the submerged forest, please use Akioh Lake Dam Park.
