Japan's coin lockers are considered some of the safest in the world and are a cornerstone of convenient travel in the country. They are found in nearly every train station, department store, and major tourist hub. In 2026, most lockers have transitioned to "cashless" systems where you pay using a Suica or Pasmo IC card, which then serves as your digital key—meaning there is no physical key to lose. For lockers that still issue a paper receipt with a PIN or QR code, it is vital to take a photo of the receipt immediately, as the thermal paper can be easily lost. While theft is extremely rare, the lockers have strict time limits (usually 3 days), after which the management company will empty the locker and move your items to a secure warehouse. For oversized items or for those seeking an extra layer of human security, staffed "Luggage Storage" counters (like those from Yamato Transport) are also widely available.
