天慶 (Tenkei, "Joy of Heaven") is Aoi Seicha's absolute pinnacle — a Heritage Grade koicha assembled exclusively from tencha leaves that have won Gold Medal prizes at Japan's elite tea industry competitions. Ground stone-fresh upon order, it scores 5/5 for umami, aroma, and richness from AOI's sommeliers. Available only in Japan through specialty channels, Tenkei represents the highest expression of Nishio matcha craftsmanship, reserved for the most formal tea ceremony contexts.

Tenkei is recommended for koicha. Thick tea — a concentrated preparation using about 4g of powder and 30ml of water, reserved for the highest-grade matcha.
