Showa period


#1

Am I correct if I say the following?:
Hirohito became the Emperor in 1926, so to convert Showa headstamp date to Gregorian calendar, one just sums up the headstamp year and 26, so Showa 17 is 17+26=1943.
I may be mis-dating my headstamps…

sksvlad:

ACCORDING TO MY SHOWA CALENDAR, SHOWA 17 = 1942. PLEASE UNDERSTAND THAT THIS MAY NOT BE CORRECT, AND UNDERSTAND ALSO I’M NOT IN ANY WAY AN AUTHORITY ON ANY OF THE JAPANESE ERAS.

GWB - you are correct that Showa 17 is 1942. Showa 18 - 1943, Showa 19 - 1944 and Showa 20 -1945. It is confirmed by presence on Type 14 and type 94 pistols that bear the Showa date of 20, but were not made after 1945 due to end of the war. When figuring the date from 1926, you must use inclusive addition - that is, the year 1926 is one. I think, and could be wrong myself, that Hirohito ascended to the throne of Japan in 1925, but that would have been the last year of Yoshoshita’s reign (Hirohito’s father) and thus 1926 was the first full year of the Showa era. The previous reign to Hirohito was call “Taisho,” by the way.
