Gyokuro
S tier
Gyokuro is a premium Japanese shaded green tea made from Camellia sinensis sinensis cultivars grown under covers for roughly two to three weeks before first harvest. Shading boosts chlorophyll and amino acids (notably L-theanine) while reducing some catechin bitterness; leaf is then steamed, rolled, and dried like other Japanese greens but aimed at a dense, needle-leaf presentation. Classic production centres include Uji (Kyoto), Yame (Fukuoka), and Okabe/Asahina areas of Shizuoka, using cultivars such as Gokou, Saemidori, and Okumidori. The liquor is deep green-gold, intensely umami and sweet-marine, with restrained astringency when brewed cool and short. Gyokuro is a ceremonial-leaning specialty tea drunk in small servings; leftover leaf may be eaten dressed with soy, and the same shading logic underpins tencha for matcha when leaves are not rolled into needles.
Also known as: Uji gyokuro, Yame gyokuro, Okabe / Asahina gyokuro, Kabusecha (lightly shaded intermediate style)

History
Yamamoto Kahei and Uji growers developed covered cultivation methods that evolved into gyokuro’s shaded leaf style.
Early commercial gyokuro from the Uji region established “jade dew” as a luxury alternative to ordinary sencha.
Refined shading cloths and cultivar selection improved consistency of high-amino-acid gyokuro leaf.
Post-war specialty marketing positioned gyokuro as Japan’s flagship shaded whole-leaf green tea.
Regional appellations such as Yame gyokuro gained strong domestic reputation for deep umami cups.
International tea culture elevated gyokuro alongside matcha as a showcase of Japanese shade-grown green tea craft.
