Vegeta-Kurun (Kanazawa Food-Waste Circulation System)
Kanazawa, Ishikawa, Japan · Operator: 金沢市（ごみ減量推進課）
Overview
Kanazawa City's food-waste recycling loop that collects citizen-made compost at neighborhood points and uses it at community farms. It advances food-loss reduction and organic-resource circulation through citizen participation.
Citizen participation
Residents compost kitchen waste at home using cardboard composters or processors and bring it to collection points. The collected compost is used at community farms, and participating residents earn redeemable points.
Operating model
A city-run organic-resource circulation scheme: partner stores collect citizen-made compost for reuse at community farms, incentivized through points (exchangeable for 500 yen of goods).
Impact
Tied to the city's food-loss reduction plan, it functions as an urban circular model that turns household food waste into a local farming resource.
Land tenure
Not a land-use case but a network-type scheme for compost collection and reuse.

Ogo Bamboo Project, Ogo-cho, Kita Ward, Kobe
JPKobe (北区), Japan
A community group based in Ogo-cho, Kita Ward, Kobe, that since 2019 has been clearing neglected bamboo groves and putting the bamboo to use. Left alone, bamboo encroaches on fields, degrades the landscape and shelters crop-raiding animals, so continuous cutting is needed to return the hills to open, managed satoyama. Under the motto "tasty and fun", bamboo and shoots are upcycled instead of discarded — into domestic menma, bamboo craft and the transmission of those skills, and fertiliser made from bamboo chips. Its bamboo-chip compost is used in the Kobe Compost Project's public workshops.
