This is a beautiful black lacquered Sanpo (altar table). The black lacquered Sanpo (kuronuri sanpo) is a traditional utensil used in Shinto and Buddhist rituals for offering food and other items. It is made by applying black lacquer or cashew paint to a white wood Sanpo. It has a more dignified feel than the standard white wood version and is widely used in temples, special Shinto rituals, for displaying Hina dolls, and for the New Year's rice cakes (kagami mochi). This one appears to have been prepared and stored as a tea ceremony utensil. There is no proof of the material, but judging by the sound, it is made of wood, not plastic. I am sure of this because I previously stored a white wood Sanpo as well. - Shape: Circular 7 sun (approx. 21 cm) in diameter Height: 11.5 cm Inner wall: 2 cm Generally, Sanpo have square legs, but perhaps because this is for tea ceremony use, the legs are divided into four. Sanpo are relatively expensive, and valuable ones can sell for around 100,000 yen. This is likely due to the black lacquer finish. Thank you for looking.
