Potager Chayama (Shimonoseki national-land share farm)
Shimonoseki, Yamaguchi, Japan · Operator: 株式会社ARCH（下関市・中国財務局との連携）
Overview
ARCH turns national land on Shimonoseki’s sloping dense streets into a share farm—cutting state upkeep on hard-to-sell plots while creating food-education and exchange near the station. A regional spread of Sakanoen-style national-land interim gardening.
Citizen participation
Residents use the share farm; planting workshops and exchange with neighbours and students follow. Inspired by Nagasaki’s Sakanoen, it uses beginner-friendly methods.
Operating model
Idle national land (escheated without heirs) entrusted via finance office → city → local firm ARCH; the community takes mowing/care while farming. Reported as Japan’s second national-land share farm after Nagasaki’s Sakanoen.
Impact
Implements national-land × city × local-business entrustment in western Japan, turning ‘worthless’ plots into community space.
Land tenure
Free entrustment of national land via the city to a local firm; interim community use of hard-to-sell plots
Crops

Scale
60 m² — 下関駅北東約500m、茶山・竹崎の斜面住宅地内の国有地（約60㎡）。車が入れない路地に面する
