Since 2004 I have traveled nearly every year to Japan. The rail pass made my life easier to discover all those amazing places in my favorite country.
This very popular place is a must-see during the blossoming of Mizubasho (Japanese skunk cabbage) in late spring/early summer and Nikko-kisuge (yellow day lily) in the end of July and during autumn season when the colorful leaves create a beautiful atmosphere. The whole area is accessible by well maintained elevated boardwalks.


Oze National Park was part of the Nikko National Park founded in 1934. On the 30th of August 2007 the park received its standalone status as the 29th national park in Japan. The beautiful marshlands of the park were created by an volcano eruption of Mt. Hiuchigatake. The lava flow blocked the river Tadamigawa and the result was the largest high moor in Japan.
