semi-residential zone; quasi-residential area
A Japanese zoning category under the City Planning Act that allows a mix of residences and certain small-scale commercial or light industrial facilities, with some restrictions on noise and scale.
Because this land is designated as a semi-residential zone, small factories can also be built.
Compound of 準 (jun, 'semi-', 'quasi-'), 住居 (jūkyo, 'residence'), and 地域 (chiiki, 'area'). The term is a legal designation under Japanese city planning law.
