01 / Otoyo Goishi-cha Tea Production Technique
Tea spread to dry on straw matslooks like stones laid on a Go board.

Steamed leaves are inoculated with mold in a chamber, packed into cedar tubs to ferment, cut into pieces about 3cm on a side and sun-dried on straw mats. The sight is thought to have given goishi-cha its name (goishi are Go stones). In March 2026 the technique was designated a national Important Intangible Folk Cultural Property.
