Oze National Park

The wetlands of Oze National Park are home to many rare and endemic plants. You're likely to come across Japanese wood poppies, daylilies and hare's tail cottongrass here. The park's mountains are covered in forests of Japanese beech, Maries fir and Erman's birch.

The park is also home to mammals such as the Asian black bear, Japanese serow and Japanese stoat, as well as a rich variety of birds and insects.



Clusters of daylilies (Hemerocallis dumortiei) bloom on Ozegahara Plateau and around Lake Ozenuma in July. The bright yellow flowers of these plants typically live only for a day.
