Hyuganatsu (Japanese:日向夏,Hepburn:Hyūganatsu; speciesCitrus tamurana), is acitrus fruit and plant grown in Japan. The name comes fromHyūga, the ancient name ofMiyazaki Prefecture inKyushu, where the citrus is said to have originated, whilenatsu (夏) means summer. Hyuganatsu grown outside Kyushu are sometimes shipped under different names such asKonatsu (小夏),Tosakonatsu (土佐小夏), orNew Summer Orange (ニューサマーオレンジ).
A hyūganatsu sapling was said to have been found in aMiyazaki garden sometime in the 1820s, after which it became widely cultivated throughout the region. It is theorized to be either amutatedyuzu or perhaps more likely, a chancehybrid between yuzu andpomelo.[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'soil is higher than other citrus fruits intrans-β-farnesene,l-carvone, and has a higher number ofketones.[2]
