紛失物(ふんしつぶつ)

Composed of 紛失(ふんしつ) (loss, going missing) and 物(ぶつ) (thing, object). This is the formal/administrative term for items that someone has lost. Japan has a well-organized lost-and-found system, and this word appears on forms, signs, and announcements at train stations, police boxes, and public facilities.

When you lose something in Japan, you can file a 紛失届(ふんしつとどけ) (lost property report) at the nearest 交番(こうばん) (police box) or at the facility where you lost it. Japan's high return rate for lost items makes knowing this vocabulary particularly practical.
