Hyuganatsu (Citrus tamurana, Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga, the ancient name of Miyazaki PrefectureinKyushu, where the citrus is said to have originated, while "natsu" (夏) means summer. Hyūganatsu grown outside Kyushu are sometimes shipped under different names such as Konatsu (小夏), Tosakonatsu (土佐小夏), or New Summer Orange (ニューサマーオレンジ).
A hyūganatsu sapling was said to have been found in a Miyazaki garden sometime in the 1820s, after which it became widely cultivated throughout the region. It is theorized to be either a mutated yuzu or perhaps more likely, a chance hybrid between yuzu and pomelo.[1]
The fruit is of medium size and its shape is round to slightly oblong. When ripe, it turns a light yellow. Its flesh is juicy and sweet with a slightly sour taste.[1] It is usually eaten cut up, sprinkled with sugar and with most of its rather thick pith intact.[citation needed]
The fruit's oil is higher than other citrus fruits in trans-β-farnesene, l-carvone, and has a higher number of ketones.[2]
