生産緑地地区

Urban Farm DB summary

This official page from the Tokyo Metropolitan Bureau of Urban Development (last updated May 26, 2026) explains Tokyo's productive green zone (seisan ryokuchi) system: designation requires a plot of at least 500 sqm (reducible to 300 sqm by municipal ordinance, with contiguous plots eligible if each is at least 100 sqm), imposes a 30-year farming obligation, and grants tax benefits (agricultural-rate property tax and inheritance tax deferral). It also explains that because zones designated in 1992 under the revised law reached the 30-year mark in 2022, the "specified productive green zone" system (created by a 2017 law amendment) allows landowners to extend the tax benefits and buyback-request window by another 10 years.
