A COVID-19 Coronavirus tracker for Japan. Government agencies release detailed data, but in difficult to read formats and usually only in Japaneese.
If you would like to update any missing or incorrect data on the graphs, please leave a comment on this spreadsheet, and/or request edit access.
Data sources we're using.
Our data is sourced from a variety of sources, primarily Japanese news outlets like NHK, prefectural governments and the Ministry of Health, Labour and Welfare.
Countrywide Sources
The Ministry of Health, Labour and Welfare (MHLW) produces several sources of data that we use to cross check and verify.
- MHLW COVID19 Information Page (新型コロナウイルス感染症について)
- MHLW COVID19 Daily Press Releases: 3/2020 2/2020. The most important document is the Patient Detail Updates (新型コロナウイルスに関連した患者の発生について) that list patient information linking to prefectural government reports.
- MHLW COVID19 Daily Summaries including aggregate counts and per-prefecture information.
NHK News is the most comprehensive and standardized reporting of infection cases per prefecture as well as a daily sum up every evening.
Prefecture-specific Data
