Oze is a national park and an excellent hiking destination in the mountains about 150 kilometers north of Tokyo. The most famous sights are the Ozegahara Marshland and the Ozenuma Pond. Oze is extremely popular during the blooming of skunk cabbages in the late spring and early summer and during the fall colors of early autumn, whereas in the winter it is covered in deep snow and is rarely visited.

Oze has numerous trailheads through which visitors can enter the park. The trails are well maintained, and there are wide elevated boardwalks that pass over the Ozegahara Marshland and around Ozenuma Pond.
