Interesting photos of the official Japanese surrender of the weapons in Batavia on 15 May 1946.
The allied representative is Major P.A.A. Haining of the Allied H.Q. The Japanese representative is Major-General Nishimura.
.
For those who are interested, these are the three swords dated Showa January 20 (1945).
If anyone knows of a sword with a later date, please let me know.
