The summer festival will feature a variety of stage events, such as acoustic guitar performances and traditional Ainu dance, as well as displays of eco-friendly cars and electric bike test rides, all of which will express the wonderful natural environment of Lake Shikotsu National Park. In addition, a limited number of "salt-grilled Lake Shikotsu tip (kokanee salmon)", which was just opened for fishing in June, will be on sale, so you can enjoy Lake Shikotsu gourmet food that can only be tasted here.
