Lakeside Museum Sharing the Story of the Legendary Kunimasu Fish
About this spot
Lake Tazawa was once home to Kunimasu, a freshwater salmon species endemic to Japan, but it was believed to have become extinct due to acidification of the water from post-war hydroelectric power channels. However, in 2010, its survival was confirmed in the distant Lake Nishi in Yamanashi Prefecture, making it a major topic. The Lake Tazawa Kunimasu Museum presents the history of Kunimasu and the nature of Lake Tazawa in an easy-to-understand manner through aquarium displays and videos. It's a family-friendly facility where you can also learn about the lake's future environmental conservation. The interior is cool, making it perfect for taking a refreshing break before swimming.

Tips
遊泳時間は8時30分から17時までと決まっているため、着替えの時間を見込んで15分前には切り上げるのがおすすめです。日中の砂浜は日差しが強いので、パラソルや帽子で日陰を確保しましょう。周辺には売店が少ない場所もあるため、飲み物は事前に用意しておくと安心です。
