Does Japan have trains for women only? If so why?

Question:

Answer:

If you read about it on some web pages, you could have already known the reason as usually pages talk about its reason.

Some guys try to molest women on trains. So women only car is to avoid it.

It's "women only car" to be accurate. Not women only train. One train has 4-10 cars. (It's less than 4 or more than 10 in some trains). And just 1 of them is a women only car.
