Hattori was one of Japan's most prolific bonsai potters. He studied at, and graduated from Koblenz University of Applied Sciences' Institute of Artistic ceramics, in Germany, and was working for a German company, when, in 1977 he started to make bonsai pots. He showed his pots for the first time at the National  Zenkoku Shobachi Meisakuten Exhibition in 1980, and has since won many awards. 
His hand signed pots are hand made by him, and glazed by him, and they display a variety of shapes and often have details such as cut corners, and sashes/bands. The many glazes he produces are recognisable as Hattori's, yet often have unique variations from the kiln.
Hattori pots are great value, well made and very useable.
