特定生産緑地指定の手引き

Urban Farm DB summary

MLIT's Urban Bureau guide (April 2026 edition) explains the Productive Green Zone and Special Productive Green Zone systems and the municipal designation procedure. Productive Green Zones require at least 500 m² of urbanization-area farmland (reducible to 300 m² by local ordinance); as of 31 December 2025, 52,955 zones covering 10,613 ha were designated nationwide. Special Productive Green Zone designation must occur before the 30-year mark from the original zoning notice; once designated, the earliest date an owner can request a buyout is deferred by 10 years, renewable repeatedly with owner consent. In the three major metropolitan areas, parcels not redesignated shift to residential-land property taxation via a phased relief schedule (0.2/0.4/0.6/0.8 of the tax base increase in years one through four).

Only numbers and their conditions are stored, as structured data — never the source's own sentences. Metric and condition names stay in English, as coded.
