The Seikyo Shimbun (聖教新聞, Seikyō Shimbun) (English: "the newspaper of sacred teachings") is Japan's third largest daily newspaper.
The publication is owned and operated by the Japanese Buddhist organization Soka Gakkai, and often features news articles about the activities of the president of the Soka Gakkai International (SGI), Daisaku Ikeda, and essays written by him, as well as news and experiences by Soka Gakkai members in Japan and abroad. The newspaper also features general news reports of domestic and international topics, and occasional articles related to Sōka University and Soka University of America.
The Seikyo Shimbun is delivered throughout Japan by volunteer deliverers.
