Terroir & Climate
At 23 metres elevation in Kyotanabeshi, this estate lies in a low-altitude coastal or valley environment typical of certain Japanese tea-growing regions. Estates at such elevations in this latitude generally experience relatively mild winters and warm, humid summers, conditions that tend to encourage vigorous vegetative growth and an extended growing season. The climate typically supports multiple harvests per year, with the low elevation often associated with earlier spring flush compared to higher-altitude counterparts.
Lower-altitude sites in this part of Japan are often characterised by richer alluvial soils and ample water availability, factors that tend to favour yield and leaf tenderness. The absence of the cooler night temperatures found at higher elevations can result in faster leaf maturation, which generally influences the balance of amino acids and catechins in the fresh leaf. Such terroir typically lends itself to the production of volume-oriented green teas, though careful cultivation and processing can yield a range of quality levels.
Tea Produced
Shogyoken Seicha Co Ltd produces green tea. Estates in this region at low elevation typically yield teas with a straightforward, vegetable-forward character, often showing grassy or marine notes common to Japanese greens. The cup profile tends to reflect the vigorous growth conditions, with a balance between umami and astringency that varies according to harvest timing and cultivar selection. Steamed processing, the norm in Japan, generally results in a bright liquor and a fresh, clean flavour that emphasises the natural qualities of the leaf.
