生産緑地法

Urban Farm DB summary

The 1974 law establishing productive green land districts: farmland inside urbanisation promotion areas keeps farmland-level taxation in exchange for restrictions on construction. The 1991 amendment paired it with residential-level taxation in the three metropolitan areas; the 2017 amendment lowered the size threshold to 300 square metres and created the tokutei (specified) designation.
