Height 19.3 cm, mouth diameter 11.1-12.1 cm, body diameter 13.5 cm, bottom diameter 12.6 cm.
The mouth is shaped like an arrowhead and the bottom is flat with a spatula under the mouth. The entire piece is fired to a soft silvery finish, with ash falling and changing on one side and a reddish finish on the other side. The reddish brown color around the hem is particularly beautiful. The hem is tight, giving it a strong and stable appearance even though it is a thin water jar. A large square mark is stamped on the bottom, but the text inside seems to be illegible. There are holes for a kanzuke at the front and back under the shoulder, but they have been filled in now.
The mouths of the bowls were probably made for kakekasei (hanging flower vases), but since the mouths were made large enough to hold a ladle, they were probably later used as thin water jars. This is probably the most representative of these works.
