Is it true that in Japan, men can touch women inappropriately and it not be sexual assault?

Question:

My friends were talking about it today at lunch. They also said that women don't have many rights, is that true as well?

Answer:

Maybe in Iran, but not Japan. Said person would be arrested.
Such things used to be common on crowded trains. But women have started to fight back. Being arrested for this would bring shame to the man and his family. There are also now ' women only ' trains during busy times.
