★It has a 300-year history and is designated as an Important Intangible Cultural Property of the country. Also known as "the world's most beautiful folk kiln," traditional techniques are passed down through single-generation transmission. Representative techniques include tobi kanna (flying plane), hakeme (brush marks), uchikake (splashed glaze), and nagashigake (dripped glaze). As you use it, cracks (nyu) appear on the surface, and oil seeps in, undergoing a unique aging process. The black glaze with a pattern resembling rice ears, as seen in the image, is called nogime tenmoku.
