Japan Coin Locker Guide
Japan's coin lockers are a traveller's best friend — store your heavy bags at the station and explore the city hands-free. Available at almost every train station and airport, they're affordable, secure, and simple to use. Here's everything you need to know.
What Are Coin Lockers?
Coin lockers (コインロッカー, koin rokkā) are self-service luggage storage lockers found at virtually every train station, subway station, and airport in Japan. They let you store your bags for a day so you can explore unencumbered. Unlike staffed luggage storage services, coin lockers are available 24 hours at most stations — though counters typically close around midnight.
Locker Sizes and Costs
Lockers come in three standard sizes: small (¥300–¥400/day, fits a daypack or small shoulder bag), medium (¥500–¥600/day, fits a carry-on or standard backpack), and large (¥700–¥800/day, fits a large suitcase or two carry-ons). Extra-large lockers at some major stations cost ¥1,000/day and can hold an oversized bag or ski equipment. Prices reset at midnight, not at a rolling 24-hour window from when you locked in.
How to Use a Coin Locker
Choose a locker, place your bag inside, and close the door. Insert coins or tap your IC card (Suica, Pasmo). The locker will lock automatically and issue or display a key/code. To retrieve: insert your key or enter your code, insert additional payment if more than one day has elapsed, and the door opens. Some digital lockers use QR codes — scan on a nearby terminal to unlock.
IC Card and Cashless Payment
Many modern coin lockers at JR stations and subway terminals accept IC cards (Suica, Pasmo, ICOCA) — look for the IC card sensor on the locker panel. Swipe to pay; the system charges the stored amount when you retrieve your bag. Older coin lockers are cash-only and require exact change. Carry ¥100 and ¥500 coins as a backup even when IC card lockers are available.
Where to Find Coin Lockers
Tokyo Station, Shinjuku Station, Kyoto Station, and Osaka's Umeda/Osaka Station have the most locker banks — look for clusters near the station exits, ticketing halls, and shopping concourses. At Narita and Haneda airports, lockers are on every terminal floor. Use the JR East's official locker search website or Google Maps to find the nearest available bank — some apps show real-time vacancy.
Tips and Troubleshooting
Lockers fill up fast on weekends, public holidays, and at peak tourist sites. Plan ahead or arrive early. If a locker is full, look for staffed luggage storage (手荷物預かり所) nearby, which often has higher capacity. Maximum storage is usually three days before the station contacts you and moves your bags. Lost key? Report to the station office — they can override the locker for a fee (around ¥2,000–¥3,000).
Frequently Asked Questions
How much does a coin locker cost per day in Japan?
Small lockers cost ¥300–¥400, medium ¥500–¥600, and large ¥700–¥800 per day. Prices reset at midnight, not 24 hours from when you stored your bag — storing overnight costs one extra day's fee.
Can I pay for a coin locker with a Suica or IC card?
Yes — newer coin lockers at JR stations and major subway terminals accept Suica, Pasmo, ICOCA, and other IC cards. Look for the IC card sensor (marked with the card logo). Older lockers are cash-only.
What happens if coin lockers are all full?
Major stations have staffed luggage storage counters (手荷物預かり所) near the main exits, which accept bags of any size for around ¥500–¥800 per item per day. Some tourism associations near temples and attractions also offer luggage storage services.
Can I leave my luggage overnight in a coin locker?
Yes, most coin lockers are accessible 24 hours, but the fee resets at midnight. Storing from 3 pm to 9 am the next day counts as two days. Maximum storage is typically three days before the station claims the bag.
Where are the most coin lockers in Tokyo?
Tokyo Station has hundreds of lockers spread across multiple concourses — look near the Marunouchi, Yaesu, and Gransta shopping areas. Shinjuku Station, Shibuya, and Ueno Station also have large banks. The JR East locker-search tool at www.jreast.co.jp shows locations and approximate vacancy.
