About

Amanatsu (甘夏) or kawano natsu daidai (カワノナツダイダイ (川野夏橙)) is a yellow citrus fruit, a cultivar that originated as a mutation of the natsu mikan (ナツミカン (夏みかん)) or natsu daidai (ナツダイダイ (夏橙)). It was discovered in 1935 in Tsukumi, Oita Prefecture, Japan. The original natsu mikan that served as the basis for amanatsu was found in Yamaguchi Prefecture around 1700.

How to grow it

Natsumikan is grown commercially in Japan, notably in Yamaguchi, Kumamoto and Ehime prefecture. The city of Hagi is famous for its natsumikans, particularly when used in natsumikan juice and ice cream.

Yamaguchi Prefecture takes such pride in their natsumikan industry that the typically white crash barriers of Japan were changed to a befitting orange.
