Asamiya vs Wazuka
Two small Kansai districts whose tea frequently reaches drinkers under a bigger name. Wazuka supplies a large share of what is sold as Uji tea; Asamiya is a tiny Shiga district counted by local account among Japan’s oldest tea areas, and its production is small enough that it is rarely named at all.

What is being compared
Point by point
| Aspect | Asamiya | Wazuka |
|---|---|---|
| Prefecture | Shiga, near Shigaraki. | Kyoto, south of the city. |
| Scale | Tiny, with small plots and a handful of producers. | Substantial, and a major supplier of tencha for high-grade matcha. |
| How its tea is sold | Occasionally under its own name; mostly it disappears upstream. | Largely as Uji tea. |
| Terrain | A small mountain district, 300 to 600 metres. | Steeply terraced hillsides, 100 to 500 metres. |
| Historical claim | Planted, by local account, from seed brought back from Tang China — a traditional attribution rather than a documented one. | No comparable origin claim; its importance is modern and industrial. |
| What to look for | A named Asamiya lot, which is a deliberate act by the producer. | A named Wazuka lot, which tells you what a generic Uji label would have hidden. |
The short answer
Both districts are worth knowing because both are usually invisible, and a producer willing to name either is telling you something about how the tea was sourced. In Wazuka’s case the name is also the practical answer to the question of where Uji matcha actually grows.
