The Uji Method refers to the sencha-manufacturing approach associated with Nagatani Soen in the eighteenth century. Also called Uji seho or aosei sencha-ho, it belongs to the history of steamed, rolled tea. It should not be used as a catch-all name for shading, hand-picking and stone-milling matcha.
Its place in Uji tea history
The Uji Tea Cultural Landscape history distinguishes several developments rather than presenting one unchanged process. It places covered cultivation, oishita saibai, in the later sixteenth century. It then describes Nagatani Soen’s method in the mid-eighteenth century, involving working the heated leaves during drying over a tea-drying furnace.
According to that account, the tea found a market in Edo before the method spread to other producing regions. Its significance lies in the manufacture and wider availability of sencha. A modern tea made through related processing need not have been grown in Uji; method and geographical origin answer different questions.
How the sencha route differs from tencha
In sencha manufacture, steaming is followed by rolling and drying. MAFF’s contemporary Kakegawa example separates rough rolling with heated air, unheated rolling to distribute moisture, intermediate rolling, fine rolling and final drying. Modern machinery changes the equipment, but rolling remains a central distinction from tencha manufacture.
For tencha, the shaded leaves are steamed and dried without rolling. They are subsequently prepared for fine milling into matcha. The Japan Tea Central Association’s labelling standard explicitly distinguishes these routes. Grinding rolled sencha does not make the earlier processing stages disappear or make that powder identical to tencha-based matcha.
Where shading and gyokuro fit
Shading is a cultivation decision made before harvest, not another word for the Uji sencha method. It can be combined with different processing routes. The historical account explains gyokuro as a later combination of covered cultivation with the Uji manufacturing method.
- Sencha route: steamed leaves undergo rolling and drying.
- Tencha route: covered-cultivation leaves are steamed and dried without rolling, then prepared for milling.
- Gyokuro route: covered-cultivation leaves receive sencha-style processing rather than becoming unrolled tencha.
This comparison explains why both gyokuro and matcha can involve shade cultivation without being the same product. The decisive difference is not simply whether a garden was covered, but what happens to its leaf material after harvest.
What the method does not guarantee
The historical name does not promise hand-picking, a fixed shading period or the selection of only exceptional leaves. Those claims need evidence about the producer and lot. Nor does it establish an automatic quality advantage over every mechanized tea: the modern process has its own controls, and the resulting tea must be evaluated as a product.
When reading a label or producer story, separate the region, cultivation and factory process. That keeps Uji’s important contributions to sencha, matcha and gyokuro visible without combining their histories into one misleading “premium matcha method.”
