Japanese Tea Terroir: Shizuoka, Uji, Kagoshima & Chado

Japanese tea is unusual in how completely processing overrides varietal character. Almost all of it is green, almost all is steamed, and most comes from one cultivar.

Steaming, not pan-firing

The decisive fork with Chinese green tea is how oxidation is halted immediately after picking.

Japan steams. China generally pan-fires.

Steaming produces the deep green colour, the vegetal and marine notes, and the slightly thicker texture of Japanese tea. Pan-firing produces the nuttier, toastier register of Chinese greens. This single processing decision accounts for more of the difference than terroir does.

Steaming duration is itself a variable. Asamushi (light steam) preserves leaf structure and gives a clearer, more delicate cup. Fukamushi (deep steam) breaks the leaf down, producing a cloudy, dense, intensely green infusion with more body and less subtlety.

Yabukita, and the cultivar question

Roughly three-quarters of Japanese tea is the Yabukita cultivar, selected in the 1950s for yield and cold tolerance.

That uniformity means Japanese teas differ less by cultivar than by processing, elevation and shading. It also means growers seeking distinctiveness now plant alternatives — Saemidori, Okumidori, Asatsuyu — which are worth seeking out if you have drunk a lot of Yabukita.

The main growing regions

Shizuoka — historically the largest producer, with a wide range of styles.

Kagoshima — southern Kyushu, warm, early harvests, increasingly dominant in volume and known for fukamushi styles.

Uji (Kyoto) — small in volume, enormous in prestige, and the traditional home of matcha and gyokuro.

Fukuoka (Yame) — celebrated for gyokuro specifically.

Reading a Japanese tea label

Sencha — the everyday standard, unshaded.

Gyokuro — shaded before harvest; sweet, intensely savoury.

Matcha — shaded, dried as tencha, stone-ground.

Bancha — later harvest, coarser leaf, milder.

Hojicha — roasted, low caffeine, nutty.

Genmaicha — blended with roasted rice.

Kukicha — stems and stalks; light and sweet.

Brewing note

Japanese greens want water well below boiling and short steeps. Gyokuro in particular is brewed remarkably cool. Boiling water turns these teas bitter fast, and that single error accounts for most disappointment with them.
