## What it is
A data visualization project and CSV dataset tracking Japan's COVID-19 situation, built from Japan Ministry of Health, Labour and Welfare press releases. It powers the Toyo Keizai Online 'Coronavirus Disease (COVID-19) Situation Report in Japan' page and publishes curated CSV files of cases, tests, deaths, and effective reproduction numbers.

## Use cases
- download japan covid19 case data as csv
- visualize covid19 trends in japan by prefecture
- get daily pcr test and positive case counts for japan
- analyze covid19 deaths and severe cases by age group
- find effective reproduction number data for japan
- build a dashboard from japanese government covid open data

## When to choose
- you need historical Japanese COVID-19 data in clean CSV form for research or reporting
- you want a reference visualization of Japan's pandemic data through early 2021

## When to avoid
- you need current or post-2021 COVID-19 data, since the repository stopped updating in January 2021 and the site stopped in May 2023
- you need real-time epidemic monitoring
