Roppongi Hills Rooftop Garden Rice Paddy & Vegetable Field
Minato, Tokyo, Japan · Operator: 森ビル株式会社（Mori Building）
Overview
A rooftop paddy and field in Mori Building's Roppongi Hills where, for over 20 years, residents and workers and their children have planted and harvested rice. A pioneering case embedding a Japanese agricultural landscape and community activity within a high-rise mixed-use development.
Citizen participation
Since the complex opened in 2003, nearby residents and Roppongi Hills workers and their children take part in hand rice-planting and harvesting in the rooftop paddy, stepping barefoot into the mud to plant seedlings. Summer programmes add aquatic-ecosystem observation and children's workshops.
Operating model
Operated by Mori Building as part of its town-development and 'machi-iku' (town-based learning) programme; the rooftop also functions as green infrastructure recycling stored rainwater for irrigation.
Impact
A widely cited model of resident- and worker-participation farming in central-city development; the roughly 20 annual rice-plantings have become a symbol of community building and green town-making.
