Lake Mashu: A Gorgeous Crater Lake – HOKKAIDO LOVE!

Lake Mashu is a mysterious lake surrounded by the pristine nature of Akan National Park. The deep blue glow of the lake attracts many visitors. The air is also clean, making it a great place to watch the stars.

Located 11-kilometers from JR Mashu Station and 12-kilometers from JR Kawayu Onsen Station is Lake Mashu. Sitting in the Akan-Mashu National Park, this crater lake attracts visitors to see its awe-inspiring clarity and color. Head to the Mashu No. 1 Observation Deck and prepare yourself for the stunning body of water that lies beneath. The uniqueness of Lake Mashu, considered to be one of the most beautiful lakes in Japan, fittingly comes with its own namesake color: Mashu Blue. While the color does change slightly depending on the time of year, such as the sublime sapphire-tinted water often seen in Winter, you will be amazed all year round. For a different kind of landscape, you can enjoy the lake covered in mist and witness the otherworldly “sea of clouds” phenomenon in the early morning from June to October.
