WW2 CIGARETTE CASE

My dad was in the service during WW2 and I came across this cigarette case he used. It has Japan engraved on the front, I think it is Mount Fuji, got a temple I think and maybe a shrine, flowers , something down at the bottom right corner. The inside has like circles going all through it plus on each side bands to hold the cigarettes in. Just plain on the back with scratches, the whole case has scratches on it. I think it is sterling silver. It is all engraved.( At the bottom of my picture is just reflection from my phone showing in it.)
