Hi everyone;
I just joined kinejapan and got a question, appreciated if one of u can 
help.
I'm searching for a title to a Japanese movie. it's a black and white 
movie probably made in 1960s and it's about prosecution of christians 
in sixteen century Japan.
a blacksmith is told to make a cross and to make people walk on it and  
those hidden christian who wouldn't walk on cross are branded Christian 
and punished. this blacksmith who is not a christian has a sister who 
is a Christian and make him see the light so to speck and I 'm not sure 
but probably he refuses to make the cross or walk on it and gets 
killed.
any suggestion?
thanks
  Moe
