A 2007 report introduces the use of sewage treatment plant rooftops as scarce open space in the densely built-up areas of Osaka, Japan, where urbanization began early. Public facilities including a citizens' allotment garden — described as the first rooftop park in Japan — were built on top of the Hanaten Sewage Treatment Plant, and the report states that these facilities have drawn many visitors since opening in April 2005, due largely to the success of the allotment garden.

Urban agriculture in Japan faces problems such as farmland reduction, farmer aging, expansion of abandoned cultivated land, and environmental pollution from livestock waste or agricultural chemicals. Urban agriculture can contribute to improving urban quality of life by supplying agricultural goods, creating landscapes, ensuring land conservation, and providing environmental benefits like biodiversity conservation. However, these issues pose challenges to the economic viability of urban agriculture.

A case report on Misawa Home's Kitasenju detached-housing district 'A Town with Herbs and Orchards', introducing edible landscaping through leasehold housing with common plazas and shared rear gardens as a model for integrating farming and community space into private housing development.

功 梶井, 和彦 武内, 洋一 松木 · Institutional Repositories DataBase (IRDB) · Japan

This abstract describes the UTokyo Repository, an online platform aimed at centrally accumulating, preserving, and disseminating various academic achievements produced at the University of Tokyo in electronic form to the world. Its main purpose is to develop digital collections, make them available online, and preserve them for long-term access.

和彦 武内, 洋一 松木 · Institutional Repositories DataBase (IRDB) · Japan

The available abstract for this 1987 Japanese paper consists only of a repository description (the University of Tokyo's institutional repository, UTokyo Repository) rather than the paper's content, so no findings, methods, or data about farmland's green-space value or the role of urban agriculture can be reported from it.

· 法令（e-Gov法令検索・348AC0000000072） · Japan

The 1973 act on conservation and promotion of urban green space, providing green space conservation areas, citizen-green-space contracts and greening districts. The 2017 amendment added the certified citizen green space scheme and explicitly positioned urban farmland as green space, joining farm policy to green-space policy.
