Gyokko Kiln is a Tokoname-ware pottery studio in Tokoname, Aichi Prefecture, one of Japan’s Six Ancient Kilns. The workshop specializes in kyusu and shiboridashi crafted from Tokoname’s iron-rich clay, prized for its natural red and black hues and subtle effect on tea flavor. Each piece is hand-thrown and unglazed, showcasing the clay’s natural texture and fired using traditional reduction techniques. Gyokko teapots are valued for their precision pouring, balance, and durability—making them a benchmark for functional tea ceramics. The kiln’s work represents the centuries-old Tokoname tradition, blending regional material authenticity with modern refinement, ideal for high-grade sencha and gyokuro preparation.
