警察署 and 交番: Police station, police box, and shared tasks
Compare a found key taken to a police station and a found wallet taken to a police box, alongside asking directions and describing a lost item.
Facility names and the tasks described
警察署 (けいさつしょ) means a police station, and 交番 (こうばん) a police box. Distinguish the names while following the task in each sentence. The examples do not reserve reports or directions exclusively for one facility.
「拾った鍵を駅前の警察署へ届けた。」 means “I took the key I found to the police station by the station.” 拾った鍵 is the item taken, and 警察署 the destination. Taking the key there does not establish its return to the owner.
A wallet taken there and directions requested
「拾った財布を近くの交番へ届けた。」 means “I took the wallet I found to a nearby police box.” The key at the police station and the wallet at the police box show an overlapping task: taking a found item to the facility. The names should not be distinguished merely by which item appears.
「道に迷ったので駅前の交番で尋ねた。」 means “I was lost, so I asked for directions at the police box near the station.” 道に迷ったので gives the reason for asking. The sentence does not add an answer received or arrival at the destination.
Describing a lost item and preserving the overlap
「警察署で落とし物の特徴を詳しく説明した。」 means “At the police station, I described the lost item's features in detail.” The item’s features are what was described, and 詳しく gives the manner of explanation. Recovery of the item or completion of an investigation is not stated.
警察署 appears with a key delivered and a lost item described; 交番 appears with a wallet taken there and directions requested. Connect the police-station and police-box names to those tasks while preserving the overlap in found-item delivery. These examples do not establish differences in size, opening hours, or lost-property procedures.
What do 警察署 and 交番 name, and what task appears in both the key and wallet examples?
Show the answer and why
警察署 names the police station, and 交番 the police box. Both examples involve taking a found item to the facility. They do not divide the places into reports-only and directions-only roles, or establish that delivery returned the item to its owner or completed an investigation.
