Citrus unshiu is a seeless and easy-peeling citrus mutant of Chinese origin, but introduced to the West via Japan. In Japan, it is known as unshu mikan (Japanese: 温州蜜柑, unshū mikan). In China, it is known as Wenzhou migan (Chinese: 温州蜜柑; pinyin: Wēnzhōu Mìgān). The Japanese name is a result of the local reading of the same characters used in the Chinese, the name meaning "Honey Citrus of Wenzhou" in both languages. It is also often known as "Seedless mandarin" (Chinese: 无核桔; pinyin: wúhé jú) or as a satsuma.
