I just watched this tonight and had to get it from Hong Kong, via Ebay. I don't agree with the last reviewer, though I recognise the comments about values of the past. That is kind of the point. The movie establishes Sato, the railroader, as a sympathetic character. He's not as cold as his exterior: he does grieve for his wife and his daughter, he does show affection and care for the girls and for his colleague etc. He is criticised and there is a constant theme about how he feels he cannot change. The fact that he should have done this or that differently makes us think about what he should or should not have done.
I found the film touching and thought that it was shot well and had a pretty decent plot. The revelation of the plot at the end was a bit of clumsy exposition, but the movie has heart and I am willing to forgive it.
