NEED HELP FINDING MOVE NAME (Japanese)

So there is this movie about this Japanese lady selling cucumbers. And this young girl goes to the country side and helps the lady. The lady, I believe, has 2 sons; teen and young one. The 2 boys and girl try to help sell cucumbers but no one is buying them. The little boy was walking on the railroad tracks and got hit by a train.

So can you help me find the movie name? Sorry if I didn't make any sense or didn't give you enough info.

Thanx

Are you not able to find it on the web? don't you remember the lady's name or something that can remind of the movie?
