Nagoya adopted an open-data policy in 2019 but didn't get a real catalogue — search, an API, a dataset map — until November 2024, five years later.

Nagoya City relaunched its municipal open-data catalogue on 25 November 2024, replacing older static data pages with a searchable site that includes an API, a map of geolocated datasets and visual dashboards. It runs on the bodik.jp/CKAN platform shared with dozens of other Japanese local governments, under an open-data promotion policy the city adopted in 2019. The catalogue makes city datasets machine-readable for the first time, but the city has not published dataset or API-call counts.
