Women-Only Car

On my way home, I got on a subway with my friend. We usually ride in a women-only-car. However, there were several men in it. We were surprised to see them and assumed that they didn’t know that it was for women only. Then, we noticed a sigh inside the car saying that men are allowed during holiday timetables, like during Obon. It also said that the women-only policy applies only on weekdays. We looked at each other and laughed.
