Languages
JAM and these public information pages are available in Japanese and English. Names originating in statistical and boundary data are displayed without changing the meaning of the source data.
About the data
JAM processes and visualizes statistics from the Portal Site of Official Statistics of Japan (e-Stat) and boundary data from Japan's Ministry of Land, Infrastructure, Transport and Tourism. Each dataset has its own reference date and limitations.
