This cute little bowl is used as a shoyu-zara or soy sauce dish and was handmade in Japan. It is glazed in a light brown with one edge "dipped" in darker brown. Was bought in a little shop on a trip to Japan in 2003 and in very good condition...was not used very often. Signed on the bottom by the artist. Measures 4" across.
