Vintage Utsuwa-No-Tajimi 3 ceramic vegetable dish set, made in Japan

This is a set of 3 ceramic vegetable dishes made in Japan that consist of a purple eggplant, red beet, and orange carrot dish. They measure between 3.75 - 5.5 inches in length and width (see pictures). This was actually part of a 5 piece set and included a tray, but I have just 3 pieces from the set. The red beet has a small chip on it (please see picture).
