I lived in Japan for ten years. Actually I was stationed in Japan for ten years, but spent a good part of that “haze gray and under way,” which is the Navy way of saying I was gone to sea a lot.
Anyway, the next flag is for the Japanese language.
I learned some Japanese while I was there, but have forgotten most of it.
Anyway, what this Japanese ornament exactly is in today’s jigsaw puzzle I’m not entirely sure.
I think it was used to heat the room by slowly burning whatever they used for fuel way back when.
Then again, it could be a stone sock drawer for all I know.
