Wetlands Characteristic of Primordial Japan

Hokkaido is home to vast stretches of wetlands that are rarely found in Japan. The wetlands were formed from the deposition of plants under Hokkaido’s cold climate. As these areas posed a challenge for human development in the past, the wetlands have been preserved in their original form since primordial times. Today, the wetlands also house a large number of special natural monuments, as well as rare animal and plant species.
