Published monthly by JMA. Updated to the month of December 2019 (published on December 24, 2019).
Brief Overview
Our Cabinet Approval Rate and Disapproval Rate are based on polling results of the following 7 media organizations: Yomiuri Newspaper, Mainichi Newspaper, Asahi Newspaper, Kyodo News, Nikkei Newspaper, NHK, and NTV. We produce simple average and trimmed average of their polling results for each month. For the trimmed average, we exclude the highest and the lowest from the poll results and take the average of the rest. Our series starts from January 2013. Prime Minister formed his cabinet at the end of 2012.
For individual polling results, please see below links for reporting on polling results in Japanese by each media. As far as we know, none of the media have a dedicated page for polling results in English.
