Amanatsu (甘あま夏なつ) or kawano natsu daidai (カワノナツダイダイ (川野かわの夏なつ橙だいだい)) is a yellow citrus fruit, a cultivar that originated as a mutation of the natsu mikan (ナツミカン (夏なつみかん)) or natsu daidai (ナツダイダイ (夏なつ橙だいだい)). 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.^[1]

Names

Amanatsu (甘あま夏なつ) means "sweet summer" in Japanese. In Japan, the fruit is known as kawano natsu daidai (カワノナツダイダイ（川野かわの夏なつ橙だいだい）), but also colloquially the amanatsu, amanatsu daidai (甘あま夏なつ橙だいだい), amanatsukan (甘あま夏なつ柑), and amanatsu mikan (甘あま夏蜜柑なつみかん（甘あま夏なつみかん）).^{[citation needed]}

Description

Natsumikan is about the size of grapefruit and oblate in shape. The fruit contains 12 segments and about 30 seeds. The rough textured fruit is easy to peel and is commonly eaten fresh. It is also used for wide variety of products ranging from marmalades to alcoholic beverages.^{[citation needed]}

Cultivation

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.^{[citation needed]}

Yamaguchi Prefecture takes such pride in their natsumikan industry that the typically white crash barriers of Japan were changed to a befitting orange.^{[citation needed]}
