A citrus fruit found in Miyazaki Prefecture, named “hyuganatsu (species of citrus, Citrus tamurana)” in 1887, it has become a specialty citrus fruit of the prefecture due to its excellent fruit and efficacy. As the name suggests, it is a citrus fruit that is a specialty of Miyazaki prefecture. It seems that it was discovered as chance seedling in Soi, which is adjacent to Jogasaki, Akae Village in the former Miyazaki District (currently Miyazaki City) from 1818 to 1829, which is the end of the Edo period. Production in Miyazaki City (Kiyotake Town / Takaoka Town), Aya Town（Succeeded in revitalizing the town with the slogans of “organic farming town” and “laurel forest city”）, and Nichinan City seems to account for about 80% of the total. Unlike other citrus fruits, it is a variety that can be eaten with albedo, and the taste is less sour than grapefruit, and the light and refreshing taste is impressive.
It has a strong taste, less acidity, and an elegant taste. It is unusual to eat the fluffy white part of the pericarp with the flesh. There is no bitterness and you can enjoy a unique texture. Many of the Greenhouse cultivated ones do not contain seeds, but the open-field cultivated ones seem to have seeds. It seems that the pollen of tetraploid Amanatsu（Citrus natsudaidai）is manually pollinated during the pollination period in early spring to denuclearize it. Those with no seeds are distributed as seedless, and those with a few remaining seeds are distributed as small nuclei.
Princess Hyuganatsu is a brand-certified product and has strict brand standards (product certification standards: presence or absence of seeds, sugar content, grade, size, etc., production area certification base, etc.) set by the “Miyazaki Prefecture Brand Promotion Headquarters”, directly from the producer. It is not possible to purchase. Regarding the cultivation method, about 30 years ago, in 1992 (Born in Kokurakita Ward, Kitakyushu City, Fukuoka Prefecture, Seicho Matsumoto, a novelist I admire and never stop, has died. He won the Akutagawa Prize in 1953) Under the guidance of the Faculty of Agriculture, Miyazaki University, he has been working on “seedless cultivation” in the greenhouse, making it mild and sweet.
Hyuganatsu (species of citrus, Citrus tamurana) is a fruit that is associated with summer, but the season is from spring to early summer, and greenhouse cultivated ones will be on the market from around December, but seasonal outdoor cultivation is 3 It tends to hit the market around the month. Locally, flowers decorate tourist spots and are enjoyed as fruits that signal the arrival of spring as a campground for professional baseball and soccer, and are loved by fans and the kindness of the Japanese people.
