Tenryū is the westernmost of Shizuoka's three mountainous tea-growing regions, with tea fields dotting the mountains that flank the Tenryū River and its tributaries. Like other mountain teas (山茶 – yamacha) from Honyama and Kawane, Tenryū tea is praised for its transparent and elegant taste, deriving from the mineral rich soil and the subtle, natural shade of fog and mountains. Compared to the Honyama and Kawane teas, Tenryu fields are typically planted further up the mountains, at higher altitudes and nestled away from pollution. Typically unshaded and lightly-steamed, Tenryu sencha is known for its clear, crisp taste, and distinctive aroma, known as yama no kaori (山の香) or mountain aroma.
Located deep within the mountains, the Isagawa valley extends off of the Fudou river, which feeds into the Keta river (a major tributary of the Tenryu river) and is part of the Haruno subregion of Tenryū. Its relative isolation remote location makes Isagawa the ideal place for organic tea cultivation as there is no risk of runoff from neighbouring farms. The organic tea plantation here spans 20 hectares running from 300-600m in altitude. The cooler temperatures and rich soils afforded by this high altitude mean no pesticides or chemical fertilisers are necessary. In addition to the natural shading that mountain plantations enjoy, the high altitude also slows the tea plant’s growth, resulting in richer teas.
Developed in 1970 from a cross between Asatsuyu and Shizu-7132, Tsuyuhikari became popular even before it was registered in 2003. Meaning ‘Dew Light’, Tsuyuhikari is an early-budding cultivar with high yield and high cold resistance.
Teas made from Tsuyuhkari boast a bright colour, a unique and rich aroma, with good body, and a mellow umami.
Brewing Instructions
Osada Seicha (おさだ製茶)
Osada Seicha is currently headed by Natsumi Osada (長田夏海), an 8th dan (level) national tea appraiser who aims to preserve and protect the natural beauty of Shizuoka by promoting organic tea cultivation. Working alongside Natsumi-san are Takeshi Suzuki and Katsutoshi Izawa, two innovative farmers who spearheaded the organic initiative in Isagawa.
Founded in 1947 and achieving its modern form in 1994, Osada Seicha pride themselves on promoting organic tea production in the mountains of Tenryu, Shizuoka. For 35 years, they have developed close ties with famers in the Isagawa valley region and work with them and other farmers and farmer cooperatives to produce high-quality organic tea. Due the small scale and remoted location of these mountain farms, they cannot refine and process tea by themselves, so Osada seicha completes the final finishing or shiage (仕上げ) of these teas.
