The submarine-type tour boat "Moguran" operates from the pier on the southeast shore of Lake Motosu. There are two windows inside the ship to look at the bottom of the lake and view the lake with high transparency, and it goes around the lake in 25 minutes while enjoying the lava approaching the east shore.

It is located on the western edge of the Five Lakes of Fuji, with a circumference of 12km, an area of 4.7 square km, and a maximum depth of 122m. The northern shore is a good observation spot for Fuji, and the view from here is adopted in the design of the old thousand yen bill. Tourism development has not progressed much within the Great Lakes, and pristine nature has been preserved, especially on the western shore. Recently, there are many young people who enjoy windsurfing and canoeing around the northwest coast.
