Everywhere in big city of Japan, There are Women-only passenger car.
Which are intended for women only.

But thinking of Gender equality, I think it’s illegal.

Though I have never ridden on Women-only passenger car,
If a man get into the women-only cars by mistake,
There are unpleasant announcement
saying “Women-only passenger car is for women”

I want to say to conductor.
“The Constitution guarantee Gender equality, You should not say it!”
