The garden lies on land belonging to the owner of Obaachan-chi. Terraces and woodland that became abandoned farmland, when the old bond between nature and people in the satoyama broke, are being restored through planting, soil improvement and environmental earthworks.

Each of its five areas has a role. In the Kayaba we grow Japanese silver grass for thatched roofs; on the Shamen slope we cut back dwarf-bamboo thickets and plant fruit trees and tea. Along the Ogawa stream, collapsing banks are rebuilt in steps with log retaining walls, and the Shitchi returns old paddies and channels to a waterside habitat. The Terrace at the entrance is where harvested materials are processed and loaded, a place to rest, and a lookout over the village.

The Kayaba is also a maintenance base for the Yasato Thatched Roof Preservation Society, and the grass cut there goes to repair nearby thatched houses. Over the hill, local residents are working to bring back fireflies, and in the paddy next door YASABI grows rice.

It is more than a source of materials. It is a park-like place where even people new to the satoyama can feel in touch with nature, and a walking path for local people. In future it will also become a place to gather fruit for a while.
