えーさんでぐちですね。まっすぐいって、つきあたりをひだりにまがってください。
A3 Exit, right. Go straight, then turn left at the end. (Alternatively: I will show you on the map.)
Gesture & etiquette
Point in the general direction you are asking about, then follow their gestures.
Speak clearly and slowly. Station staff are usually very helpful, but they might point to a map or give detailed directions quickly.
