Ozegahara, at an altitude of 1400m, is the largest and highest wetland on Japan's main island of Honshu. Located in a National Park, the rare ecosystem of Oze is also a Special Protection Area. Every year, around 300,000 hikers flock to Oze. The unique marshlands are home to around 300 species of grasses and flowering plants, including the white skunk cabbage. In Oze, spring, summer and autumn are compressed into the 5 months between mid-May and mid-October. During that brief period, plants bud, flower and bear fruit. We explore the beauty of Oze's 4 seasons.
