A Kogaratsu Kawakujira-type (Iron glazing lip) cup fired in the early Edo period. It is moulded roughly with sandy taupe clay, and the lip is slightly outwarded and shows Bebera (a point worthy of note: the ridges of the lip). It is also a highlight that there is a part of the streaking iron glaze where the wood ash turned pale blue with kiln effects. It is a praised and perfect Kogataratsu Guinomi—sake cup.

There is an extremely thin lip chip and a careful lacquer repair. Although the Kawakujira-type was widely made in the Karatsu ware kilns, it is precious that it retains its original figure and is regarded as a sake set or a teacup. It fits in a paulownia wood box with the inscription “Karatsu Kawakujira Guinomi Momoyama period”.
