オタトマリ沼 Otatomari-numa Otatomari Marsh
|
Otatomari Marsh is a marsh with an area of 9.1 ha, located in Oniwaki Numaura, Rishirifuji-cho in the south of Rishiri Island in Hokkaido. The name “Otatomari” means a sand harbor in Ainu. Seen from the marsh, Mt. Rishiri, with the top covered with glacier snow, looks like an Alpine mountain. Otatomari Marsh is famous for the reverse images of Mt. Rishiri on the surface of the water. The bottom of the volcanic crater became moorland to form a marsh, which is surrounded by wetland and the northernmost primeval forest of Yezo spruce in Japan. The bed of the forest is covered with Sphagnum , and if you walk into the forest, your ankles will soak into the mud. When you walk along the promenade around the lake, you will enjoy the extensive scenery with Yezo daylilies and beachhead irises blooming in early July. The marsh is also known as the place for migratory birds to come flying. You can leisurely enjoy the natural features at Otatomari Marsh.
