Japan Coin Lockers Guide: Sizes, Prices & How to Use Them

Japan coin lockers are easy to find at many train stations, airports, bus terminals, and tourist facilities. They are best for storing a suitcase or backpack for a few hours while you sightsee or wait for hotel check-in.

The important catch is that lockers are not standardized nationwide. Size labels, dimensions, prices, payment methods, the time at which a new “day” begins, maximum storage periods, and opening hours depend on the station, facility, operator, and locker model. Read the instructions on the exact locker before paying.

Quick Answer: How Do Coin Lockers Work in Japan?

Find an empty compartment that fits your bag, place the bag inside, close the door, and follow the lock or touchscreen instructions. A traditional cash locker normally gives you a physical key. A modern electronic locker may use a transport IC card or a receipt with a PIN or QR code as the key.

Most lockers charge per use or per calendar-based storage period, not by the number of times you open the door. In an ordinary locker, removing your luggage ends the rental. If you want to store it again, you normally need to start a new rental and pay again.

Before walking away:

  • photograph the locker number, locker bank, and nearby exit or landmark;
  • keep the key or receipt safe;
  • if you used an IC card, remember which card or device you used;
  • check when an additional fee begins and the final collection deadline; and
  • confirm that you can return while the station or building is open.

Do not leave your passport, cash, medication, electronics, or anything needed for your next train or flight in a locker unless the posted terms clearly permit it and you accept the risk. Locker rules commonly exclude cash, valuables, dangerous goods, animals, perishable or odorous items, and other unsuitable contents.

Where Can You Find Coin Lockers in Japan?

Coin lockers are common at major and mid-sized railway stations. JNTO's luggage-storage guidance also notes that various sizes are available at most stations and tourist facilities. You may find them at subway stations, airports, bus terminals, shopping centers, museums, theme parks, and sightseeing sites.

Inside a station, look for the locker pictogram or the words “Coin Lockers.” Common locations include:

  • near ticket gates or station exits;
  • along underground passageways;
  • beside concourses or waiting areas;
  • inside or outside the paid area; and
  • in an attached station building or shopping complex.

The side of the ticket gate matters. A locker inside the paid area may require a valid ticket or another fare-gate entry when you return. A locker outside the gates is usually easier if you will continue sightseeing away from the railway.

At a large interchange, note the railway operator, floor, gate, and exit—not only the station name. “Shinjuku Station locker” is not enough when JR, private railways, subways, and shopping buildings occupy a wide area. Save a map pin or take a wide photo showing a nearby sign.

Japan Coin Locker Sizes

Locker labels such as small, medium, large, extra-large, S, M, and L are not universal measurements. Even one operator can list a range because locker models differ. The practical rule is simple: compare all three dimensions of your bag with the dimensions printed on the locker, then check the door opening and protruding wheels or handles.

The table below is a planning guide based on current official examples from Kintetsu Railway and JR East Smart Logistics. It is not a nationwide specification.

Locker label Typical use Illustrative official dimensions Common price examples
Small Daypack, handbag, compact shopping bags Roughly 26–43 cm high, about 34–36 cm wide, and about 43–66 cm deep in the cited systems Often around ¥400–¥600
Medium Larger backpack, small carry-on, soft bag Roughly 41–70 cm high, about 25–46 cm wide, and about 43–66 cm deep Often around ¥400–¥700
Large Many cabin-size or medium suitcases Roughly 64–87 cm high, about 33–36 cm wide, and about 43–66 cm deep Often around ¥600–¥1,000
Extra-large or LL Some large suitcases or tall items Examples range from about 102 cm to over 170 cm high; widths and depths vary substantially Often around ¥800–¥1,500 where offered

These price ranges reflect Kintetsu’s published conventional-locker examples as of August 2026. Smart, reservable, airport, or unusually large lockers can cost more. Always use the price displayed at the actual location.

Small Lockers

Small lockers are the most common. They work well for a daypack, handbag, small shopping bags, or a folded jacket. They are usually too short for a conventional rolling suitcase, even if the suitcase’s width looks suitable.

Do not assume a “carry-on” will fit a small locker. Airline cabin-bag limits and locker openings measure different things, and wheels can make the case taller than its advertised body size.

Medium Lockers

Medium lockers often fit a larger backpack, duffel, or compact carry-on. A soft bag has an advantage because it can compress slightly, but do not force it through the opening or against the door.

Because the medium label covers a wide range, check the actual internal dimensions. A bag that fits one operator’s medium locker may not fit another one.

Large Lockers

Large lockers are usually the first option to try for a rolling suitcase. Many cabin-size cases and some medium cases will fit, provided the width and depth work. Large lockers are fewer than small lockers at many locations and can fill first at busy stations.

An extra-large or LL locker may be needed for a bigger suitcase, but these compartments are not available everywhere. If your trip depends on one, check an official station map or a real-time locker search service where available, and keep a staffed counter as a backup.

Will Your Suitcase Fit?

Measure the suitcase at its widest points, including wheels, side handles, feet, and hard-shell curves. Compare height, width, and depth; the longest dimension alone is not enough.

Do not rely on liter capacity or labels such as “24-inch suitcase.” Manufacturers measure cases differently, and the door frame or hinge may reduce usable clearance.

For Shinkansen travel, locker fit is a separate question from onboard baggage rules. If the total of your bag’s three dimensions is over 160 cm on certain Shinkansen routes, you may need an oversized-baggage-seat reservation even if you found a station locker earlier. See our guide to Shinkansen oversized baggage before boarding.

How Much Do Coin Lockers Cost in Japan?

At many stations, conventional lockers cost a few hundred yen per storage period, with larger compartments costing more. JNTO gives ¥300–¥600 as a broad visitor-facing expectation, but current operator examples show that large, extra-large, smart, and airport lockers can be higher. Kintetsu currently lists conventional lockers from ¥400 to ¥1,500 depending on size and location.

Treat any online range as an estimate. The displayed price on the locker is the price that matters.

Also check how the operator defines a day. A daily charge does not always mean 24 hours from the moment you pay. JR East Smart Logistics says its conventional locker date changes at 2:00 a.m. Narita Airport says a daily-rate locker’s day ends at midnight, while Kansai Airport says a new day begins at 2:00 a.m. A late-evening deposit followed by an early-morning collection can therefore trigger another day’s fee, depending on the locker.

Traditional key lockers may require ¥100 coins. Modern units may accept transport IC cards, and some smart or airport lockers also accept credit cards, QR payments, or other cashless methods. Do not assume every locker accepts both cash and IC cards.

How to Use a Coin Locker Step by Step

First inspect the price, payment logos, hours, storage limit, prohibited items, and contact number. Choose the compartment only after checking your bag against the displayed dimensions.

Cash Lockers

The exact mechanism varies, but a traditional key locker usually works like this:

  1. Find an empty compartment and confirm that the key is present.
  2. Put your bag inside and close the door fully.
  3. Insert the displayed amount, often using ¥100 coins.
  4. Turn the key and remove it.
  5. Check that the door is locked, then photograph the locker number and location.
  6. To collect the bag, return to the same locker, insert any additional fee if required, and turn the key.

Some cash lockers use a central touchscreen and issue a receipt or PIN rather than a physical key. Follow the on-screen language option and keep the receipt. If you lose the key or retrieval information, call the number posted on the locker. The operator may ask for identification and a description of the contents, and a service fee may apply.

Cash-only lockers may not have a change machine nearby. Carry several ¥100 coins or be ready to find a convenience store or ticket machine area where you can obtain change. Never leave an unlocked bag in the compartment while you go to find coins.

IC Card Lockers

Tourists can use an IC card at a compatible locker. Look for the Suica, PASMO, ICOCA, or nationwide transport e-money logos; compatibility depends on the machine.

A typical IC-card process is:

  1. Put the bag in an empty compartment and close the door.
  2. Select “Store” or the equivalent option on the control panel.
  3. Choose IC card payment.
  4. Touch the same physical IC card or supported mobile IC device to the reader until payment is confirmed.
  5. Take the receipt if one is issued. It can identify the locker and help you contact support.
  6. To retrieve the bag, select “Remove” and touch the same card or device to the reader.

JR East’s official Suica guidance states that Suica can act as both payment and the locker key at compatible lockers and cannot be combined with cash for that transaction. The exact procedure differs by machine.

Use the same card or phone that locked the compartment. Do not refund, delete, transfer, or replace that IC card before collecting your luggage. Keep enough balance for any additional fee. If the reader fails, use the posted support contact instead of repeatedly trying unrelated cards.

How Long Can You Leave Luggage in a Coin Locker?

Coin lockers are short-term storage. Many operators use a maximum of about three days, but this is not a national rule. JR East Smart Logistics, for example, states a maximum rental period of three days from the start date. Narita Airport publishes a maximum of eight days for its listed daily-rate lockers, while Kansai Airport publishes up to ten consecutive days for the lockers on its current page.

Check three separate items on the exact locker:

  • the maximum rental period;
  • the time when another day’s fee is added; and
  • the hours when the locker area can be accessed.

If you exceed the permitted period, the operator may unlock the compartment, inspect the luggage, and move it to a separate storage facility. You can be charged additional storage or handling fees. Under JR East Smart Logistics’ published rules, uncollected luggage is moved after the three-day locker period, kept separately within a stated 30-day period from the start date, and may then be treated as abandoned and disposed of. Other operators set their own procedures and deadlines.

Do not use a station locker for a week without verifying that the particular locker permits it. For a longer gap, choose a staffed long-term storage service or change your luggage plan.

Can You Access Your Locker More Than Once?

Usually, no. Standard coin lockers are designed for one deposit and one final retrieval. When you unlock the door to remove something, the rental normally ends. Closing the door again generally requires a new payment, and the compartment could become available to someone else.

Some newer services advertise special multiple-access plans, but that is an exception with its own conditions. Unless the screen explicitly says you can reopen the locker during the rental, pack as though you will not open it again.

Keep your passport, wallet, medication, phone charger, rail tickets, and anything needed before collection in your day bag.

Are Coin Lockers Available 24 Hours?

Not necessarily. A locker can be physically present all night but inaccessible because the station gates, underground passage, airport zone, or shopping building closes.

Station lockers are often available from the first train until the last train, depending on their location. A locker in an outside, street-accessible area may operate longer. As a concrete example of local variation, Osaka Metro’s Higashi-Umeda coin-locker service center publishes hours of 7:30 a.m. to 10:30 p.m.; it is not a 24-hour facility.

Plan around access, not only the train timetable. If your bag contains something needed for a late flight or early departure, confirm the locker area’s current opening hours on the facility’s official page or posted sign.

What to Do If Coin Lockers Are Full

Large lockers are the most likely to be unavailable at busy stations, especially around weekends, holidays, event days, and hotel checkout time. If the first bank is full:

  1. Check the station map for another locker bank on a different floor, concourse, or side of the gates.
  2. Look for a real-time availability terminal, QR code, or official locker search page. Some JR East Multi-Ecube locations support search and reservation; JR West provides real-time locker availability tools at selected stations.
  3. Try a nearby station on your actual route rather than crossing a huge terminal with luggage.
  4. Split small bags across smaller lockers only if the total cost and collection plan make sense.
  5. Use a staffed station counter, your hotel, or another short-term storage service.

Do not force a suitcase into a smaller compartment or leave it unattended beside the lockers. If a large locker is essential, arrive early and have a named backup before starting the day.

Using Coin Lockers at Major Japanese Stations

Major stations generally have lockers, but their size is exactly why travelers lose track of them. Use the official station map and record the gate and floor.

  • Tokyo Station: JR East’s station page confirms coin lockers. Tokyo Station has multiple rail zones and extensive underground passages, so save the exact gate, floor, and Marunouchi or Yaesu side.
  • Shinjuku Station: JR East’s official map shows station facilities across several levels. Search by the operator and gate you will actually use; “east” and “west” are not precise enough on their own.
  • Shibuya Station: JR East’s station page confirms coin lockers, but ongoing station layouts and access routes can change. Follow current signs and do not rely only on an old blog map.
  • Kyoto Station: JR West’s official station map marks coin lockers and a baggage room. Its hands-free-travel page links to real-time availability for supported stations, including Kyoto. Check whether your locker is on the north/central side, Hachijo side, or inside a paid area.
  • Osaka Station: JR West’s current station map marks coin lockers, and JR West’s travel tools offer real-time availability at supported locations. Remember that JR Osaka Station and the neighboring Umeda stations belong to different operators and occupy a large connected district.

At any of these stations, allow extra walking time. The nearest empty locker on a map may still be several levels or passageways away.

Common Coin Locker Mistakes Tourists Make

Assuming all “large” lockers are the same. Size names are operator labels, not a national standard. Measure the bag and check the actual compartment.

Forgetting the retrieval location. Photograph the locker number, bank identifier, nearest gate, floor, and a wide view of the surrounding sign.

Leaving the wrong essentials inside. Keep your passport, medication, wallet, tickets, electronics, and next layer of clothing with you.

Expecting free access all night. A station or building can close even while the locker remains rented.

Misunderstanding the fee reset. An extra daily charge may begin at midnight, 2:00 a.m., or another posted cutoff—not necessarily after 24 hours.

Using the wrong IC card at retrieval. The same card or mobile device normally acts as the key.

Opening the door “just for a minute.” Standard lockers normally end the rental when opened; another payment may be required.

Keeping luggage beyond the limit. The bag may be removed to another facility, with extra fees and a separate recovery process.

Storing prohibited or high-risk items. Read the terms. Cash, valuables, dangerous goods, perishables, and other unsuitable items are commonly excluded.

Alternatives When You Cannot Use a Coin Locker

Use an alternative when every suitable locker is full, your luggage is too large, the access hours do not work, or you need storage beyond the posted limit.

Option Best for Main limitation
Coin locker Self-service storage for a few hours near your route Fixed compartment size; large lockers may fill
Station luggage counter Oversized bags or full locker banks Staffed hours, last-collection time, and capacity limits
Hotel storage Before check-in or after checkout Usually limited to guests; confirm the hotel’s policy
Airport storage counter Flight-day storage or longer airport stays Terminal hours, fees, and item restrictions
Temporary storage service Reservable space near busy areas Location-specific hours and online booking terms
Luggage forwarding Moving a suitcase between destinations Not instant; delivery timing and receiving arrangements matter

For a multi-city trip, luggage forwarding in Japan can remove a large suitcase from difficult transfers. It is a delivery service, not a substitute for a locker when you need the bag again in a few hours.

Japan Coin Locker FAQ

Are coin lockers easy to find in Japan?

Yes, at many major and mid-sized stations and tourist facilities. Small rural stations and minor entrances may have few or none, so check the official station page when storage is essential.

How do coin lockers work in Japan?

Place your bag in an empty compartment, close it, and pay using the method shown. Keep the physical key, receipt, PIN, QR code, or IC card used as the retrieval key.

Will a suitcase fit in a Japanese coin locker?

Many carry-on and medium suitcases fit large lockers, but there is no universal size. Measure the wheels and handles and compare all three dimensions with the posted compartment size.

How much do coin lockers cost in Japan?

Many conventional lockers cost a few hundred yen, with larger units costing more. Current official examples extend from roughly ¥400 to ¥1,500, but the actual fee depends on the operator, location, size, and locker type.

Can tourists use IC cards for coin lockers?

Yes, at compatible lockers. Look for the accepted transport IC logos and use the same card or mobile device to retrieve the bag.

Can you pay for coin lockers with cash?

Many traditional lockers accept cash, commonly ¥100 coins. Some electronic or smart lockers are cashless. Check the payment symbols before placing your bag inside.

How long can luggage stay in a coin locker?

Many station-locker operators allow around three days, but limits vary. Airports and other facilities may publish longer limits. Read the terms on the exact locker.

What happens if you leave luggage too long?

The operator may open the locker, move the bag to separate storage, charge additional fees, and eventually dispose of unclaimed property under its terms. Contact the number posted at the locker as soon as possible.

Where are coin lockers usually located?

Look near ticket gates, exits, underground passages, concourses, waiting areas, and attached station buildings. Check whether the locker is inside or outside the paid area.

Are large lockers hard to find?

They are available at many major stations but are generally fewer and can fill sooner than small lockers. Search other locker banks or use an official availability tool where offered.

Can I reopen a locker after paying?

Usually not without ending the rental. Standard lockers are normally one deposit and one retrieval. Only rely on multiple access if the specific service explicitly permits it.

Are coin lockers open 24 hours?

Not always. Access can be limited by station, passageway, or building hours. Confirm that you can return before the area closes.

What should I do if no locker works for my bag?

Use a staffed station or airport counter, ask your hotel, book a temporary luggage-storage service, or arrange forwarding for a transfer between destinations.

Bottom Line

Japan coin lockers are a practical way to store luggage for a few hours, and tourists can use them without special registration in most cases. The safest routine is to measure your bag, check the exact price and time rules, keep retrieval information, and photograph the location.

Do not plan around a nationwide “standard”: sizes, fees, payment methods, access hours, and maximum storage periods vary. Large lockers can fill quickly, so identify another locker bank or staffed counter before you arrive. Use a locker for short-term convenience; use hotel storage, a counter, or forwarding when the bag is too large or the timing does not fit.
