Noob entry...
This tray is a representation of a Tensho Oban Japanese gold coin.
Dimensions, etc., are:
Length: ~6-5/8"; Width: ~4-1/4"; Depth: ~3/16"; Circular Mark Diameter: ~3/16"; Weight: 79.4 grams
The blank circular space in the lower right-hand area of the tray corresponds to the location of the mark on the back.
I have tried without success to use your site to identify this mark.
Probably the failure is mine for being unfamiliar with the site, and overlooking search options.
This tray was purchased (or traded for) during the American occupation of Japan (GHQ Era; 1945-1952) by my father's older brother, probably in Nagoya, where he was stationed during that entire time.
I'll be very grateful for any and all of your comments, and especially help in identifying when and by whom it was made.
Thanks for looking...Warren
