Sazae-san is a Japanese yonkoma manga series written and illustrated by Machiko Hasegawa. It was first published in Hasegawa's local paper, the Fukunichi Shinbun (フクニチ新聞), on April 22, 1946. When the Asahi Shimbun wished to have Hasegawa draw the four-panel comic for their paper, she moved to Tokyo in 1949 with the explanation that the main characters had moved from Kyūshū to Tokyo as well. The first Sazae-san strip run by the Asahi Shimbun was published on November 30, 1949. The manga dealt with everyday life and contemporary situations in Tokyo until Hasegawa retired and ended the series, with the final comic published on February 21, 1974.

Manga are comics or graphic novels originating from Japan. Most manga conform to a style developed in Japan in the late 19th century, and the form has a long history in earlier Japanese art. The term manga is used in Japan to refer to both comics and cartooning. Outside of Japan, the word is typically used to refer to comics originally published in Japan.
