Konatsu

Hyuganatsu (Japanese: 日向夏, Hepburn: Hyūganatsu; species Citrus tamurana), is a citrus fruit and plant grown in Japan. The name comes from Hyūga, the ancient name of Miyazaki Prefecture in Kyushu, where the citrus is said to have originated, while natsu (夏) means summer. Hyuganatsu 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).
