If you’ve ever arrived at Tokyo Station with a heavy suitcase and a full day of sightseeing ahead of you, you already understand why coin lockers are one of the most useful things in Japan. I’ve watched so many visitors drag rolling luggage through narrow shrine corridors or crowded izakayas simply because they didn’t know how straightforward it is to store their bags and move freely. Once you know how the system works, it changes your entire travel experience.
This guide covers everything you need to know about how to use coin lockers in Japan — from finding one and understanding the sizes to paying and retrieving your bags without stress.
Where to Find Coin Lockers in Japan
Coin lockers (コインロッカー, pronounced koin rokkā) are everywhere in Japan, but the best spots to look are major train stations, subway stations, bus terminals, and popular tourist areas.
JR stations are your most reliable option. Tokyo Station alone has over 800 coin lockers spread across multiple floors and exits. Other major hubs like Shinjuku Station, Kyoto Station, and Osaka Station are similarly well-stocked. If you’re heading to a tourist site, it’s also worth checking whether the destination itself has lockers — Asakusa, Ueno, and Akihabara all have locker banks near their main station exits.
When lockers at the station are full (and they do fill up fast on weekends and during cherry blossom season), look for ecbo cloak (ecbo.io/cloak), a popular luggage storage service that lets you book space at convenience stores, cafes, and shops across Japan. I’ve used it myself during Golden Week when every locker in Shinjuku was taken by 9am.
Coin Locker Sizes and Prices
Understanding locker sizes before you arrive saves a lot of frustration. As of 2026, most coin lockers in Japan come in three standard sizes:
– Small (S) — fits a daypack or handbag. Typically ¥300–¥400 per day.
– Medium (M) — fits a carry-on or small suitcase. Typically ¥500–¥600 per day.
– Large (L) — fits a full-size rolling suitcase. Typically ¥700–¥900 per day.
“Per day” in Japan means until midnight, not 24 hours from when you locked it — that’s an important distinction I’ll come back to. If your bag stays past midnight, you’ll be charged for an additional day. Bags left for more than 3 days are typically removed and taken to a station lost-and-found office.
Extra-large lockers do exist at some stations, designed for large backpacks or ski bags, but they’re less common and usually cost ¥1,000 or more.
How to Actually Use a Coin Locker: Step by Step
The process is simple once you’ve done it once. Most modern lockers in Japan accept both IC cards (like Suica or Pasmo) and coins. Some older lockers are coin-only, so it helps to carry a few ¥100 coins just in case.
Here’s the process for a standard electronic locker:
1. Find an available locker — look for a green light or “空” (あき, aki, meaning “empty”). A red light or “使用中” (しようちゅう, shiyōchū) means it’s occupied.
2. Open the door, place your luggage inside, and close it firmly.
3. Select your payment method at the nearby terminal — IC card or coins.
4. Pay the fee. The terminal will display the locker number and issue a receipt or a key (depending on the locker type).
5. Save your locker number and receipt. You’ll need both to retrieve your bag.
To retrieve your luggage, return to the same terminal, enter your locker number, pay any additional time fees, and the locker will release. According to the East Japan Railway Company (JR East), their station lockers are monitored and covered under their standard station security procedures, so your belongings are well-protected.
What Foreigners Often Get Wrong
This is where I see the most avoidable stress, so pay attention.
Mistake #1: Thinking “one day” means 24 hours. As I mentioned above, the locker resets at midnight — not 24 hours after you lock it. If you store your bag at 11pm on a Tuesday, by 12:01am on Wednesday you’ve already been charged for a second day. I’ve seen travelers end up paying for two days when they only needed the locker for a few hours overnight.
Mistake #2: Not saving the locker number. Electronic lockers don’t give you a physical key — they give you a number. If you forget it, retrieving your bag becomes a stressful conversation with station staff. Take a photo of the terminal screen or your receipt the moment you complete the transaction.
Mistake #3: Assuming lockers are available everywhere, anytime. During peak travel periods — Golden Week (late April to early May), Obon (mid-August), and cherry blossom season (late March to April) — lockers in popular areas fill up by mid-morning. Have a backup plan, whether that’s ecbo cloak or asking your hotel to store your bags.
Mistake #4: Trying to fit an oversized bag. Japanese coin lockers are standardized and not very flexible. A large hiking backpack with a frame often won’t fit in even an L-size locker. Check the locker dimensions posted on the door or look for the extra-large (LL) option at major stations.
FAQ
Can I pay for a coin locker with a credit card?
Most coin lockers in Japan still only accept IC cards (Suica, Pasmo, ICOCA) or coins. A small number of newer lockers at international airports and major stations now accept credit cards, but don’t rely on it. Carry ¥100 coins as backup.
What happens if I lose my locker receipt or forget my number?
Go to the station’s lost and found office (忘れ物センター, wasuremono sentā) or the nearest station master’s office (駅長室, ekichō-shitsu). Bring your ID. Staff can verify ownership and open the locker for you, though this may take some time.
Are coin lockers safe for valuables like laptops and passports?
They’re generally considered safe for short-term storage. Japan has an exceptionally low theft rate in public spaces. That said, I’d recommend keeping your passport on you whenever possible, and never leave cash or irreplaceable items overnight.

Conclusion
Coin lockers are one of those small systems that, once you understand them, make Japan feel incredibly easy to navigate. In my experience supporting travelers new to Tokyo, the ones who use coin lockers well end up having noticeably better days — they move faster, see more, and aren’t exhausted from hauling luggage up shrine steps.
My personal recommendation: store your bags at the first major station you arrive at, keep your locker number photographed, and plan to retrieve everything before midnight. With a little preparation, this becomes second nature by day two of your trip.
