Oze National Park


  • Sunday - Monday (National holiday), 15-16th September (two-day hike)

  • Located in Gunma/Honshu

An exciting overnight hike through the picturesque Oze marshlands.


We are headed to the Ozegahara Marshland, a fantastic and very scenic hike. The trails are well maintained and elevated boardwalks allow an unforgettable hike above marshlands. We will stay in a Japanese mountain hut, visit Hiraname Falls, Lake Ozenuma.


Oze has a very dark night sky with the Milky Way often visible.

Tour activities

Ozegahara Marshland

The marshlands are one of the most well known features of Oze. It is popular in spring with the Asian Skunk Cabbage, followed by the white fluffy Cotton-grass seeds and yellow flowering daylilies in summer. The adjacent mountain towering in the distance are the volcanic remains that created the marsh.

Hiraname Falls

70 meters across and 500 meters high, slides gracefully down the one-plate rock bed of the Tadami River. Cascading white water over the rock slope provides a striking contrast to the dark green foliage beside the river. Sanjo Falls lies farther downstream, and various smaller falls appear almost from nowhere as hikers stroll through the wonders of Oze.

Sanjo-no Taki Falls

A magnificent waterfall located downstream of Hiraname-no Taki Falls, and can be viewed from an viewing platform accessed by descending a little from the trail. All the rainfall in Oze passes through this waterfall in a tremendous roar.

Mt. Hiuchigatake

Along with Mt. Shibutsu, Mt. Hiuchigatake is one of Oze’s best-known mountains. It has five peaks formed by a series of eruptions; three of them overlook Lake Ozenuma and Ozegahara Marsh.
