Commemorating the return of the Crown Prince
Issued on September 3, 1921 (Taisho 10)
In March 1921 (Taisho 10), Crown Prince Hirohito embarked on a trip around European countries in order to gain a deeper insight into overseas countries. In July of the same year, it was decided to issue a stamp to celebrate the return to Japan, but due to the short production period, offset printing was adopted for the first time. All four designs are the battleships "Katori" and "Kashima".
