[History] In 1932, at the Kagoshima Prefectural Agricultural Experiment Station, mating was carried out with the introduced species Ai2 from India as the mother and the native species Nka03 from Kagoshima as the father, and selected from the seedling group. In 1933, it was tested in an excellent primary tree determination test for black tea, and its superiority was recognized. In 1940, it was named Deer Atssum Mating No. 1. In 1953, it was registered in the No. 13 forest in Japan and was named'Hatsumomiji'.

[Early] Mesozoic species. It is almost the same as'Yabukita' in both germination and plucking period.

[Morphological characteristics] The shape of the tree is a little upright, with strong tree vigor and maximum stocking. The arrangement of tea buds during the plucking period is good. A bud type with a large number of buds and a large bud weight.

[Cutting rooting] Good.

[Good or bad initial growth] Good. Is a variety that is very easy to grow,

[Method for tailoring young trees] The first pruning is carried out at a position slightly lower than that of'Yabukita' because the shape of the tree is slightly upright and the tree vigor is strong. After that, follow the “Yabukita”.

[Yield] Many. More than'Yabukita, Honored by Onii'.

[Quality] Tea quality is medium. The water color is crimson and slightly faint with a mild aroma. The taste is strong, but it is refreshing, and it is good after the dull place. Fermentability is slightly poor.

[Cold resistance] Cold resistance in winter is moderate to slightly weak. Medium for laceration type frost damage.
