はい、階段を渡って向かい側のホームに行けば、そのまま戻れますよ。
はい、かいだんをわたってむかいがわのほーむにいけば、そのままもどれますよ。
Yes, if you use the stairs to go to the opposite platform, you can head back just like that.
Gesture & etiquette
Point back in the general direction you came from or look toward the stairs/bridge.
Do not exit the ticket gates (IC card touch gates) unless instructed, or you will be charged extra. Ask station staff or check the platform signs first.
