Marunuma Kogen Tree Adventure

The Tree Adventure Course

This camera overlooks the Tree Adventure aerial obstacle park at Marunuma Kogen, where rope bridges, climbing walls and elevated platforms are threaded through a stand of tall conifers. It is a hands-on outdoor adventure attraction that lets visitors move through the canopy.

A Forest at Marunuma Kogen

The park sits within the dense spruce and fir forest of Marunuma Kogen, a highland resort in Katashina. Straight evergreen trunks and a soft forest floor give the scene its quiet, immersive woodland character throughout the year.

Below Mount Nikko-Shirane

Marunuma Kogen unfolds on the flanks of Mount Nikko-Shirane, the highest peak in northern Kanto, reached by the resort's ropeway. The surrounding alpine terrain makes this one of Gunma's premier mountain recreation destinations.

Gunma's Highland Playground

Part of a wider resort that shifts between ski slopes and green-season activities, Marunuma Kogen draws families and outdoor enthusiasts to the Tone District highlands of Gunma in central Japan.
