This is a Daimonomono Koseto tea caddy. The “Chakki Mereishu” (Tea Utensils and Tea Cooking) states, “Kaga Ienaka Kamiya Naizensho Mochi”, which indicates that he took this surname as his name. The “Rinpoho Kameryu” describes it as “a wet persimmon with a blackish-black pattern and a blackish-black hue, with some spots broken and others streaked, with a strong chokuro, a strong kanake on the black, a lustrous finish, and a little roughness in the clay black and the main thread cut. It was handed down from the Kamiya family to the Osaka Kagiya and Ueda Saburoemon, and has been in the Kamiya family since 1778, when Matsudaira Fumai bought it for 300 ryo.
