Coin Lockers: Sizing, Cost, and the Real Risk of None Available
Coin lockers at Japan stations store day bags and full suitcases for a few hundred yen a day, but large units at major stations sell out early on busy days.12 Plan the size, the fee, and a fallback before you arrive with a heavy bag.
Fees, rules, and requirements can change. Confirm current details at the Japan National Tourism Organization and the station operator's official pages.
Overview
A コインロッカー (koin rokka, "coin locker") is a self-service storage box at stations and tourist facilities: you place a bag inside, pay the daily fee, and retrieve it later with a key, PIN, or IC card tap.2 Most banks serve day trips, pre-check-in arrivals, and post-checkout departures when carrying a suitcase would slow the day down.
The network belongs to JNTO's Hands-Free Travel system alongside delivery and staffed storage, and JNTO warns directly that lockers in very busy locations fill up very quickly.1 That warning is the point of this guide. Sizes, prices, payment types, and time limits below are dated so you can plan around current terms, and the fallback section covers what to do when the large units are gone.
Where Lockers Are and How to Find Them
Station lockers cluster near ticket gates, in underground concourses, and around major exits, with extra banks at airports, department stores, shopping centers, museums, and ferry terminals.2 At large stations the banks spread across multiple floors and exits, so one full bank rarely means the whole station is full.
Inside and outside the ticket gates
Lockers sit both inside the ticket gates (the paid area) and outside them (the free area), and the distinction matters for retrieval.2 A bag stored inside the gates needs a valid ticket or fare to re-enter after you exit, so place same-day departure bags outside the gates when you can (as of 2026-06; confirm current station layouts with the operator).23
Tokyo Station shows how lopsided one station can be. Most lockers concentrate on the Yaesu side serving Shinkansen traffic, while the Marunouchi side holds fewer banks and higher competition for each unit.3 When the nearest bank is full, walk to another exit, floor, or concourse before giving up.23
Airports, tourist sites, and shopping areas
Airports, department stores, shopping centers, museums, and ferry terminals carry their own locker clusters beyond the rail network.2 Airport banks can allow longer storage windows than city stations, so confirm the posted maximum per airport rather than assuming the standard station rule applies.4
Sizes and What Actually Fits
Locker tiers run small, medium, large, and extra-large, though many smaller stations stop at large. Small units take handbags and small backpacks, medium units take carry-on luggage and larger backpacks, and large units take full-size suitcases.2 Extra-large units appear only at major stations and fill first in busy periods (as of 2026-06; confirm current availability with the station operator).2
Small and medium tiers for day bags and carry-ons
Small lockers suit a handbag, shopping bags, or a small backpack. Medium lockers add a carry-on suitcase or a larger backpack without forcing the door shut.2
Operator dimensions confirm the shape. Kintetsu publishes small units at 260 to 326 mm high and medium units at 405 to 567 mm high, with widths around 246 to 360 mm and depths around 425 to 645 mm depending on the unit.5 JR East Smart Logistics publishes S units around 342 to 355 mm wide by 575 to 663 mm deep by 190 to 426 mm high and M units around 342 to 461 mm wide by 575 to 663 mm deep by 413 to 696 mm high, varying slightly by location.6
Large and extra-large tiers for full suitcases
Large lockers are the full-suitcase tier, and extra-large units take oversized or double bags where offered. Kintetsu publishes large units at 640 to 868 mm high and extra-large units at 1,020 to 1,135 mm high, with widths around 246 to 360 mm and depths around 425 to 645 mm depending on the unit.5 JR East Smart Logistics publishes L units around 342 to 355 mm wide by 575 to 663 mm deep by 842 to 872 mm high and LL units around 342 to 461 mm wide by 575 to 663 mm deep by 1,049 to 1,762 mm high, varying slightly by location (as of 2026-09).6
Supply is the honest constraint. At Tokyo Station, large suitcase-size units account for only about 20 percent of each bank, and one new 283-unit Yaesu bank lists just 9 extra-large against 79 large, 79 medium, and 116 small (as of 2026-04).3 Kintetsu counts show the same skew: Osaka-Namba lists 1 extra-large against 118 large, 18 medium, and 82 small, while Kintetsu-Nara lists 65 extra-large against 254 large, 107 medium, and 163 small (as of 2026-08).5
Cost by Size and Location
Fees are set per locker size by the local operator, and central-city stations price higher than rural stations within each band. Typical 2026 bands converge on small 300 to 500 yen, medium 400 to 700 yen, and large 600 to 1,000 yen per day, with extra-large at 800 to 1,500 yen where offered (as of 2026-08; confirm current figures with the station operator).527
| Size | Typical range per day | As of | Notes |
|---|---|---|---|
| Small | ¥300–500 | 2026-08527 | Day bags and shopping bags |
| Medium | ¥400–700 | 2026-08527 | Carry-on suitcases |
| Large | ¥600–1,000 | 2026-08527 | Full-size suitcases; top of band at Tokyo, Kyoto, and Osaka hubs |
| Extra-large (major stations only) | ¥800–1,500 | 2026-085 | Oversized or double bags; few units per bank |
Figures in this table reflect 2026 operator and guide bands taken together (as of 2026-08).527 Kintetsu's own table runs extra-large 800 to 1,500 yen, large 600 to 1,000 yen, medium 400 to 700 yen, and small 400 to 600 yen, while Japan Experience reports small 300 to 500 yen, medium 500 to 700 yen, and large 700 to 1,000 yen or more at major cities and airports (as of 2026-08).52
Central-city versus rural price bands
Tokyo, Shinjuku, Kyoto, and Osaka hubs sit at the higher end of each band, and regional stations sit lower for the same size (as of 2026-05).7 Staffed station luggage counters, the manned alternative inside major stations, run about 700 yen per bag per day as practical texture rather than an operator tariff (as of 2026-05).7
Calendar-day billing and multi-day charges
Most station lockers bill by calendar day rather than by the hour, so leaving a bag past the reset adds another full day's fee.2 JR East Smart Logistics lockers reset the date at 2 AM daily, which means storing at 11 PM and retrieving at 8 AM spans two charged days.6
A minority of station guides describe 24-hour-period billing instead, so billing base varies by operator and the locker face instructions govern (as of 2025-09).7 Either way, overnight storage inside the 3-day window simply adds another day's charge per reset.62
How to Pay and How to Open Them
Traditional lockers are key-operated and take 100-yen coins only, and some stations have no coin changer on site.57 Modern touchscreen lockers at major stations accept 交通系ICカード (kotsukei IC kado, "transportation IC cards") such as Suica, PASMO, and ICOCA (see IC Cards for Visitors: Suica, Pasmo, ICOCA, and the 2023 Compatibility Changes), while older units stay coins-only.127
Coin-only, IC-card, and touchscreen types
Key lockers follow a simple flow: place the bag, pay the fee, close the door, and take the key.2 Touchscreen lockers replace the key with a PIN code or digital receipt, and IC-card taps can lock and unlock the door without anything to lose.2 JNTO confirms that many modern facilities accept various IC transit cards for payment (as of 2026-09; confirm current payment terms with the station operator).1
App-reservable smart lockers
Internet-connected smart lockers add cashless payment and, at some stations, reservations and services beyond storage. Kintetsu Smart Lockers support cashless payment, and at selected stations a same-day hotel-delivery option to around 160 Osaka City hotels runs from the touch panel with IC-card payment when baggage is left by 2 PM (as of 2026-08).5 Kintetsu's published Smart Locker fees run higher than standard lockers, with medium at 2,300 yen and small at 1,900 yen in the same table (as of 2026-08).5 JR East Smart Logistics Multi-Ecube lockers support search, reservation, storage, receipt, and sending functions across their network.6
Time Limits and Removal to Storage
The standard maximum rental is 3 days from the start date at JR East Smart Logistics lockers, and most station lockers follow the same 3-day ceiling before staff remove unclaimed items to a separate facility.62 After the first day each date reset adds another day's fee until the limit (as of 2026-09; confirm current terms with the station operator).62
Standard 3-day limit and station handling
JR East Smart Logistics unlocks the unit after 3 days, inspects the luggage, and transfers it to a designated facility for up to 30 days at the same daily rate as the original locker; unclaimed items after 30 days are treated as discarded.6 Retrieval of removed items needs station staff help and can require identification, the receipt, and extra fees.23
Overnight and multi-day planning
Overnight storage is allowed inside the 3-day window, with each reset adding another day's charge.62 For longer needs, staffed baggage counters or luggage delivery services fit better than a locker.2 Airport lockers may allow longer windows than city stations, so confirm per airport rather than assuming the station rule (as of 2018-11).4
When Large Lockers Sell Out: Fallbacks That Work
Large lockers at major stations and popular day-trip departure points genuinely sell out during peak seasons and peak-hour windows, leaving latecomers without a unit. The decision below follows the situation, not the other way around.
Hotel baggage storage before check-in and after checkout
Many hotels hold luggage before check-in and after checkout for guests staying that day or night, and this is often the simplest fallback because it costs nothing extra (front-desk procedures are covered in Check-In in Japan: ID, Deposits, and What to Expect at the Front Desk).3 Policies vary by property, so confirm at the front desk rather than assuming every hotel offers it. Station counters add a second staffed option with set hours and flexible size limits for oversized bags (as of 2026-04).3
Reservable storage services and apps
ecbo cloak is a luggage storage service connecting travelers with shops, cafes, stations, and post offices that hold bags by advance reservation, including oversized items that do not fit standard lockers.8 Locations span major cities in all 47 prefectures, multi-day storage depends on the shop, and the reservation, payment, and pickup run through a phone or browser.8
Standard pricing is 500 yen per day for bag size (longest side 45 cm or less) and 800 yen per day for suitcase size (anything larger), tax included, with a 20 kg weight limit and JR-station locations excepted at 1,000 yen per bag regardless of size (as of 2023-08; confirm current figures with ecbo cloak).9 Older app listings quoting 400 and 700 yen are superseded by the help-center figures above (as of 2023-08).98 Charges run per business day rather than per hour: crossing a shop's closing time, or midnight at a 24-hour shop, starts a second day's charge.9 Payment runs by credit card online, with on-site payment at some shops only.98
Forwarding the bag instead of storing it
宅急便 (takkyubin, "door-to-door parcel and luggage delivery service") sends suitcases hotel to hotel or to and from airports, typically arriving the next day so transfer days need only a day bag.24 Same-day delivery exists on limited routes with morning cutoffs and stays route-dependent; it is not a same-hour service, so plan handoffs a day ahead on most routes.4
Delivery carries its own limits: commonly around 160 linear cm, 25 to 30 kg, and contents under 300,000 yen, excluding valuables, fragile items, fresh products, liquids, and hazardous materials (as of 2026-09).1 The companion forwarding guide covers cutoffs and hotel procedures in full once published.
Good to know
Morning beats afternoon for large lockers
Large and extra-large units are a small share of each bank and go first on weekends, holidays, and peak-season days.73 Aim for before 10 AM at Tokyo, Shinjuku, Kyoto, and Osaka hubs, and when the nearest bank is full, check other exits and floors before leaving the station.73
A locker inside the gates needs a ticket to retrieve
A bag stored in the paid area cannot be retrieved after exiting without re-entering on a valid ticket or fare.23 Tokyo Station guides flag this as a common tourist mistake, so place departure-day bags outside the gates when the itinerary does not allow re-entry.3
Photograph the bank location, not just the door
Large stations hold hundreds of similar lockers across exits and floors, so a door photo alone does not relocate the bank.3 Photograph exit names, floor numbers, nearby shops, and the station map, plus the receipt holding the locker number and location.3
Keep valuables and same-day needs on you
Lockers are not the place for cash, passports, valuables, perishables, or anything urgently needed the same day.13 Malfunctions, forgotten locations, and removal-to-storage retrieval all take staff time, and delivery and storage services carry parallel exclusions for valuables, fragile items, fresh products, and hazardous materials.16
