Sango-sō Gunraku

Nature Reserve in Abashiri

Known as salt pickle or grasswort in other parts of the world, coral grass, an otherwise humble marsh plant, gets its moment of fame in September when it turns bright red. There are a few boardwalk viewing spots over Sango-sō Gunraku (literally 'coral grass clusters') about 10km west of town at Notoro-ko (能取湖).
