The kishu mikan is a hybrid variety of mikan, or mandarin orange, found in Southern China and also grown in Japan. It is not closely related to the common sweet orange, but it is closely related to the mandarin orange.
The fruit is also known as Baby Mandarin, Tiny Tangerine, Mini Mandarin and Kishu Mandarin. It is sold under the brand name "Cherry orange" in Europe. It is shaped like a mandarin, between 25 and 50 mm (0.98 and 1.97 in) in diameter. The fruit's orange skin is thin and smooth.
Some varieties of kishu, such as the mukakukishu, are seedless. The species is used in creating seedless hybrid citrus. The largest variety is the hirakishu.
