Hattori is a graduate of Germany’s Koblenz University of Applied Sciences’ Institute of Artistic Ceramics. While employed at a German company, in 1977 (Showa 52) he embarked on the path of creating bonsai pots. Hattori debuted his shohin pots in the national exhibition (Zenkoku Shobachi Meisakuten) in 1980 (Showa 55). He received the Tokoname City Nagamitsu Ceramic Arts Prize two years in a row, in 1998 and 1999 (Heisei 10-11). He doesn’t form his pots using a mold, and while he makes the classic shapes,rectangular, square, hexagonal, elliptical, round and other shapes, the varieties are abundant His use of glazes also aims to use as many of the standard colors as possible, but his ceramics have many nooks and crannies in the corners and edges so that the colors change in the kiln. There are many connoisseurs who enjoy these unintentional effects, so they are shipped out as is. Hattori, who shapes, glazes and fires his pots by himself is certainly one of the most prolific of artists. Throughout Japan, he has many admirers and his pots’ superior qualities are spoken of highly. One aspect of Hattor's glaze is the patina that develops very quickly adding even more interest to his pots .
