Whisked powdered tea and the Song tea competitions
Powdered tea whisked into a bowl with a bamboo whisk, judged on the whiteness of its foam and how long the foam clung to the bowl. This is the direct ancestor of matcha, and it is Chinese.
Roughly the tenth to thirteenth centuries
A process, not a moment. This happened over a period rather than on a date, and the span is the honest answer.
Documented. Attested in the historical record, and sourced to it.
The version that circulates
That matcha is a Japanese invention, or that whisked powdered tea originates in Japan.
What the evidence carries. That the preparation is Song Chinese, that it was transmitted to Japan by monks in contact with Chinese monasteries, and that its disappearance in China and survival in Japan is what makes it read as Japanese today. Japan's contribution is real and is a different contribution: shade-growing the leaf, and the ceremonial form built around the drink.
What happened
Cake tea was ground to a powder, sifted, placed in a bowl, and whisked with hot water into a suspension with a standing foam. Competitions — doucha — judged the result on the colour of the foam and on how long it resisted forming a watermark at the edge of the bowl. Dark Jian ware bowls were preferred because they showed a white foam against a black glaze.
Why it matters
Everything about Japanese matcha practice is here already: the powder, the sifting, the bamboo whisk, the bowl chosen to show the foam, the attention to suspension rather than infusion. What Japan received in the twelfth century was this, and what Japan then did was keep it after China abandoned it.
