I don't have much info, but if anyone has seen this film, the title would help me out a bunch. 
It's about a very secular, non-traditional businessman (i think Japanese, but I could be wrong) who is convinced to go on a very traditional trek to the place where his parents were killed (I believe somewhere in greenland or antarcitica--definitely a lot of snow). 

Unfortunately, that's all I remember, except that it was an excellent film. 

Has anyone else seen it?
