Small vases such as koshigaraki. The shape is small, similar to a tea urn. The large bottom of the jar resembles a person sitting down, and the tilted head is also interesting. There are two types of Koshigaraki and Ko-Iga washi. The pot-shaped ones, about 20 cm high, were formerly used by farmers as bean caddies or tea pots, while the ones about 11 or 12 cm high and shaped like a seated person were also used as oil pots.
Both types were made before the Muromachi period (1333-1573) as a side job for farmers, and were later converted to flower vases and prized as Wabimono (Wabi-ware) by tea masters. The shape is odd, the bottom is burnished, and the thick blueish-yellow color flowing from the mouth to the shoulder makes tea masters lavishly pay large sums of money for them. In addition to Koshigaraki and Ko-Iga, there are other names such as Karatsu Uzumaru, which are sometimes used because of the similarity of the shapes. (Iga and Shigaraki, Shiota Rikizo)
