About This Destination

Japan's most beloved highland marsh, with wooden boardwalks winding through vast alpine wetlands blanketed by skunk cabbage in spring and golden grasses in autumn.

Oze National Park is a pristine highland marshland straddling four prefectures, best known for its wooden boardwalks traversing vast wetlands filled with alpine flowers. The park's mizubasho (Asian skunk cabbage) blooms in late spring attract hikers from across Japan, while autumn brings golden grasses and early snowfall on surrounding peaks. This protected wilderness offers some of Japan's most rewarding day hikes through landscapes largely unchanged for millennia.

Frequently Asked Questions

How do I get to Oze National Park?

Common gateways include Hatomachitoge Pass (a bus from Numata or Tokyo via Tokura) for the Ozegahara marsh. Private cars are restricted on the final approach, so you transfer to shuttle buses.

What is Oze famous for?

It is Japan's largest highland marsh, crossed by wooden boardwalks. White mizubasho (skunk cabbage) bloom in late May to June, and golden grasses with nikko-kisuge day lilies follow in summer.

When is Oze open and what should I bring?

The hiking season is roughly late May to October, as the boardwalks are snowbound otherwise. Bring proper walking shoes and rain gear, stay on the boardwalks, and carry out all your rubbish.
