はい、〇号車が女性専用車両です。ただ、今は時間外ですので、男性の方もご利用いただけます。
はい、まるごうしゃがじょせいせんようしゃりょうです。ただ、いまはじかんがいですので、だんせいのかたもごりよういただけます。
Yes, car number [X] is the women-only car. However, it's outside operating hours right now, so men may also use it.
Gesture & etiquette
Look around the platform, then back at the staff with a questioning gesture.
Women-only cars are usually clearly marked and often only active during morning/evening rush hour. Entering one as a man when it's active is a major breach of etiquette.
