About this data Source: Center for Systems Science and Engineering (CSSE) at Johns Hopkins University. The daily average is calculated with data that was reported in the last seven days.

About the data

Nationwide and regional data for Japan comes from the Center for Systems Science and Engineering at Johns Hopkins University and does not include cases or deaths connected to the 2020 Olympic games in Japan or aboard the Diamond Princess cruise ship, which experienced a Covid outbreak while docked in a Japanese port in 2020. Johns Hopkins reports data for Japanese prefectures starting in April 2021. Population data from the Statistics Bureau of Japan.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible. For agencies that do not report data every day, variation in the schedule on which cases or deaths are reported, such as around holidays, can also cause an irregular pattern in averages. The Times uses an adjustment method to vary the number of days included in an average to remove these irregularities.
