It is said to have originated when monks who studied at Zen temples on Mount Tianmu in Zhejiang Province, China, brought back black-glazed tea bowls for tea drinking when they returned to Japan during the Kamakura period. Later, these bowl shapes were called Tenmoku tea bowls and Tenmoku shapes regardless of the glaze, and black-glazed items were called Tenmoku regardless of the shape, and black glaze was called Tenmoku glaze. Please refrain from purchasing if you are looking for a perfect condition item like a modern product. We look forward to your purchase.
