The Kushiro Marsh, the Kushiro River and its tributaries which run through it, are the largest marsh in Japan. The greatest attraction is the vast view of this natural spectacle that captivates millions of people. Apart from its unequivocal beauty and charm, it is also the habitat for numerous rare fauna and flora including the Japanese red-crowned cranes; a special natural monument of Japan.

Most of the vast Kushiro Marsh is designated as a national park, inside which there is the Kushiro Marsh Observatory, Onnenai Wooden Path through the marsh, Hosooka Observatory, Kottaro Marsh Observatory and many other scenic spots. It is also the hub for many outdoor activities such as canoeing and horse trekking.
