Mitsuru is a unisex Japanese given name. It is composed of two kanji characters: "mitsu" (美) meaning beautiful and "ru" (塁) meaning base, referring to a baseball term, though it can also mean fortress in other contexts. Thus, the name can be interpreted as 'beautiful fortress' or 'beautiful base'. Mitsuru is used for both boys and girls, with its usage more common among males. It was popular during the 1970s and 1980s but has since declined in popularity. Notable individuals named Mitsuru include Japanese actor Mizuhara Mitsuru and manga artist Koizumi Mitsuru.
"Mitsuru saw its first births in 1921 with a total of five."
