Item comes from an estate and it is not marked.  If I were to venture a guess, I would think it was made in Japan.  It is in good condition with no chips or cracks.  It measures approx 8.75 x 6 inches on the bottom.  The top is 5.75 x 4.75 inches.  There is a spot along the rim where the glaze is worn to the ceramic. There is also a small hole on the handle that looks like it was an air bubble.
