Lake Notoro Coral Grass・Notoroko Sangoso Festival

“Notoroko Sangoso Festival” Held in mid-September

Lake Notoro, a massive saltwater lake with a surface area of 580,000 square meters, overlooks the Sea of Okhotsk in Eastern Hokkaido. When September hits, the lake turns a beautiful shade of crimson, all thanks to the growth of a unique aquatic plant that locals call “coral grass.” The contrast between the ruby red of the coral grass and the sapphire blue of the lake is jaw-droppingly stunning and can not be missed. A wooden walking path snakes leisurely through the lake, so visitors during this special season should take a stroll through this mysterious coral-like wonder.
