Iyokan

The iyokan (伊予柑 - Citrus × iyo), also known as anadomikan (穴門みかん) and Gokaku no Iyokan, is a Japanese citrus fruit, similar in appearance to a mandarin orange, with Dancy as the pollen parent and Kaikokan as the seed parent. It is the second most widely produced citrus fruit in Japan after the satsuma mandarin (Citrus unshiu). Ehime Prefecture accounted for 90% of Iyokan production in 2021.

Iyokan was discovered in 1886 in the orchard of Masamichi Nakamura, a resident of Yamaguchi Prefecture. In 1889, Yasunori Miyoshi, a resident of Ehime Prefecture, bought the original tree and brought it home, and it became a specialty of Ehime Prefecture. Originally marketed as "Iyo mikan", it was renamed "Iyokan" in 1930 to avoid confusion with Unshu mikan (Citrus unshiu). The name "Iyo" was taken from the ancient name of a place in Ehime Prefecture, the Iyo province.
