The Kaigetsudō school (懐月堂派, -ha) was a school of ukiyo-e painting and printmaking founded in Edo around 1700–1714. It is often said that the various Kaigetsudō artists' styles are so similar, many scholars find it nearly impossible to differentiate them; thus, many Kaigetsudō paintings are attributed to the school's founder, Kaigetsudō Ando, which may have been in fact painted by his disciples. While the school of course produced many unique works, many were based on reproducing very similar poses or images, with only the colors or kimono pattern changed.
