Kiyomi (清見, kiyomi) (Citrus unshiu × sinensis) is a Japanese citrus fruit that is a hybrid of a Miyagawa Wase mikan and an orange.[1] 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"[2] in 1979.[3]

Hybrid parentageC. unshiu × sinensis

Kiyomi are sweet. Sugar content is normally 11–12°Bx and reaches even 13°Bx if conditions are met. Citric acid content is around 1%. It has no seeds. The time of ripening is mid to late March.[3] The flavor is similar to that of a mikan, while the aroma is similar to that of an orange.[citation needed]

Kiyomi is a monogerm, so it is often used as a parent citrus to create new hybrids such as Dekopon.
