A suribachi is a Japanese grinding bowl used for crushing ingredients. The inside has ridged grooves called "kushime," and a surikogi (wooden pestle) is used to grind the ingredients. It is mainly used for grinding sesame seeds, tofu, yams, and the like. The technique of creating the uneven surface of the bowl, as seen in the image, is called "shinogi," and the gradation of the glaze creates a striped pattern.
