[Can you see the sea of ​​clouds?] The charm of Lake Mashu

Lake Mashu is the second most transparent lake in the world. The blue color created by its transparency, Mashu Blue, is a truly mystical color. In fact, Lake Mashu was originally the most transparent lake in the world. The reason it became number two is because farmed fish and crayfish were released into the lake. These fish included Uchida crayfish and cherry salmon, which were presented to the Emperor. Therefore, Lake Mashu has no natural enemies and is home to crayfish of incredible size. Lake Mashu has no rivers flowing in or out of it. Since there is no water flowing in or out, the water is incredibly clear. Of course, it is impossible to go down to the lakeside. However, it seems that a water quality inspection team descends once a year, and the first three people can go for 400,000 yen...
