This neat little incense case is formed to be in a shape of biwa, a type of Japanese lute. It is a fine-grained white pottery, on which the strings are painted with iron pigment and carefully covered with glaze. The countless fine cracks called Kannyu, spread all over the surface, which adds a savor to this piece. It is a Kenjo Karatsu ware which was produced in the late Edo period (19th century) from the official kiln of the domain for the offering to Edo shogunate. This refined piece has a different attractiveness from the old Karatsu ware in the early Edo period (17th century) which has a rough and simple taste.
