Biwa Maps Japan’s Redevelopment Future

An interactive map of more than 1,100 urban redevelopment projects across Japan, layered with land prices, hazards, population projections, station traffic, crime data, and local points of interest.

Why it surfaced

Biwa turns a dense collection of public datasets into an exploratory map for understanding how Japanese neighborhoods may change. It also explains its provenance and limitations unusually carefully, distinguishing official GIS boundaries from estimated shapes and identifying the ministries, police departments, OpenStreetMap data, and other sources behind each layer.
