Kiyomi (清見, kiyomi?) is a Japanese citrus fruit that is a hybrid (Citrus unshiu × Citrus sinensis) of a Miyagawa Wase mikan and a Citrus sinensis orange. The new breed was the first tangor created in Japan in 1949. It was named Kiyomi after the temple Seiken-ji (清見寺?) and the lagoon Kiyomi-gata (清見潟?) near its experiment station in Shizuoka city and registered as "Tangor Nōrin No.1" in 1979.
Kiyomi are sweet. Sugar content is normally 11–12°Bx and reaches even 13°Bx if conditions met. Citric acid content is around 1%. It has no seeds. The time of ripening is mid to late March. The flavor is similar to that of a mikan, while the aroma is similar to that of an orange.
Kiyomi is monogerm, so that it is often used as a parent citrus to create new hybrids such as Dekopon.
