Chushingura, directed by Inagaki,1962,is almost certainly the version you're after.There have been several films of this famous tale of 47 Ronin.Japan's greatest director Kenji Mizoguchi,did another well-known version in 1942-The Loyal 47 Ronin of the Genroku Era, in black and white.If you look carefully in one of Woody Allen's films-i'm pretty sure it's Manhattan- you'll see Chushingura sign outside a cinema, so i guess he likes it.
