Japan’s 2020 Commuting-Flow Comparator
A Japanese-language tool for comparing commuting and school travel between prefectures and across 1,896 municipalities, using 2020 census data.
- For
- Readers comparing Japanese municipal commuting patterns
- Worth noticing
- It explicitly warns that its census snapshot is from October 1, 2020—not a picture of current commuting.
Field notes
The tables derive from Japan’s 2020 Population Census workplace-and-school-location tabulations, including tables 6-1 and 6-2, and distinguish movement within a municipality, within a prefecture, and across prefectural borders. Users can sort prefecture measures and search municipalities; the page also describes the top 70 inter-prefecture flows and reports 272,500 nonzero municipality pairs. Its own caveat is important: these figures describe October 1, 2020, not current commuting patterns.
