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 Prefecture in Kyushu, where the citrus is said to have originated, while {{Nihongo|"natsu"|夏}} means summer. Hyūganatsu grown outside Kyushu are sometimes shipped under different names such as {{Nihongo|Konatsu|小夏}}, {{Nihongo|Tosakonatsu|土佐小夏}}, or {{Nihongo|New Summer Orange|ニューサマーオレンジ}}.

Origin

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.{{cite journal|last=Willard Hodgson|first=Robert|title=Horticultural Varieties of Citrus|journal=The Citrus Industry|year=1967|volume=1|url=http://websites.lib.ucr.edu/agnic/webber/Vol1/Chapter4.html#pummelos|access-date=15 February 2012|url-status=dead|archive-url=https://web.archive.org/web/20120205061009/http://websites.lib.ucr.edu/agnic/webber/Vol1/Chapter4.html#pummelos|archive-date=5 February 2012}}

Description

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. It is usually eaten cut up, sprinkled with sugar and with most of its rather thick pith intact.{{Cn|date=January 2021}}

The fruit's oil is higher than other citrus fruits in trans-β-farnesene, l-carvone, and has a higher number of ketones.{{cite journal|last=Choi|first=Hyang-Sook|author2=Sawamura, Masayoshi|title=Composition of the Essential Oil of Hort. ex Tanaka (Hyuganatsu)|journal=Journal of Agricultural and Food Chemistry|date=1 October 2000|volume=48|issue=10|pages=4868–4873|doi=10.1021/jf000651e|pmid=11052747}}
