どのような忘れ物ですか？いつ頃、どの方面の電車に乗られましたか？
どのようなわすれものですか？いつごろ、どのほうめんのでんしゃにのられましたか？
What kind of item did you lose? Approximately when and on which direction train were you riding?
Gesture & etiquette
Look distressed, perhaps mimic patting pockets or searching through a bag.
Be prepared with specific details: what was lost, its description, the train line name, approximate time of travel, and the direction of the train. Do not expect it to be found immediately.
