Thanks v much Milly
I had exhausted online options and Ancestry don't have anything on Japanese POW's
So, it looks like the NA is my only option. Never taken that route before, so thanks for the nudge in that direction.
I'll start with the Japanese POW index cards and hopefully that will me lead somewhere. Then possibly the Japanese POW Questionnaires (thanks for the links)
I'm very confident he was using his given name, he didn't know where he came from, no one did.
cheers
