Coin lockers in Tokyo stations are generally intended for short-term use, with a maximum storage duration of three consecutive calendar days. Each "day" typically resets at midnight or 2:00 AM, meaning if you store an item at 11:00 PM and pick it up at 8:00 AM the next morning, you will be charged for two days of usage. If you leave your items past the three-day limit, station staff will typically remove the contents and move them to a central storage facility, where you can claim them within 30 days for a significantly higher fee. However, some larger hubs and airport terminals (like Narita Terminal 3) offer specialized lockers that can be used for up to five to seven days. For even longer-term storage in 2026, travelers should use staffed baggage counters like Sagawa or Yamato Transport, which can store items for up to 30 days. It is worth noting that modern Tokyo lockers are increasingly "IC card" compatible, allowing you to pay and unlock using your digital Suica or Pasmo card rather than physical coins.
