Farmers and Regions

Where our tea comes from, region by region. What each Japanese tea region grows and how much, the producers we met and filmed there, and which One with Tea matcha comes from where. Production figures come from our open Japanese Tea Production by Prefecture dataset.

I started One with Tea because I couldn't find a matcha supplier I actually trusted. Every time I asked for lab results or sourcing details, I got vague answers or silence.

So I went to Japan myself. I spent months visiting farms across Uji, Nishio, Shizuoka, Kagoshima, and Miyazaki, meeting the people who grow the tea, watching the stone-milling process, and documenting everything on film.
