Tokyo Coin Lockers by Station: Sizes, Costs and Finding an Empty One

The short version: for most gaps in a Tokyo day, a station coin locker will sort you out, and you’ll have better luck at a mid-sized station than a famous one.

Shinjuku, Shibuya, and Tokyo Station are where everyone looks first. That’s exactly why their lockers are full.

A nomad’s calendar is full of awkward in-between hours. You check out of a monthly apartment at ten and can’t get into the next one until four. You’ve got a client call at two and a night bus at eleven. You’d like to spend the afternoon in a museum without dragging a suitcase through it.

Tokyo handles all of this unusually well. It’s much nicer to learn how it works now than to figure it out in a panic.

How station coin lockers actually work

Pretty much every Tokyo station of any size has coin lockers. They’re usually near a ticket gate, and often tucked around a corner with no English sign.

There are roughly three sizes. Small fits a daypack or a laptop bag. Medium fits a carry-on. Large fits a checked suitcase, and those are the ones that run out.

Prices vary by station and size. As a rough guide, small lockers tend to cost in the low hundreds of yen per day and large ones a few hundred more. Treat any figure you read online as approximate, this one included.

Most newer lockers run on IC cards. You touch your Suica or PASMO to the panel, the door locks, and that card is now your key. There’s no physical key to lose, which is a real relief on a day when you’re moving between four places.

Older lockers still take 100-yen coins and hand you a physical key. If you run into one, you’ll want a small stack of coins on you. They won’t take a 1000-yen note, and the change machine isn’t always nearby.

A locker isn’t really storage. It’s what lets you move around the city without your bags choosing your route.

Here’s what catches people out: the billing day doesn’t run twenty-four hours from when you drop the bag off. At most railway lockers it resets at 2 a.m. (some places, like Narita Airport, switch at midnight), so a bag left overnight usually gets charged as two days even if it only sat there for eight hours.

Most lockers also have a maximum stay, commonly around three days. After that, staff empty the locker and move your bag to a designated storage spot, often the station office, and you get it back by paying whatever fees have built up. How long they keep it there and how you collect it depend on the operator, so if you might go over the limit, check the panel or the operator’s notice first. Either way, you’ll lose an afternoon to paperwork.

Station by station: where to actually look

Every big Tokyo station has more than one bank of lockers, and most people only ever find the first. Here’s roughly how the big six behave.

Tokyo Station. The biggest and the most confusing. Lockers are spread across the Marunouchi side, the Yaesu side, and the underground level, and once you’re inside, the three areas barely feel like the same station.

If the first bank you reach is full, try the underground concourse or the far end of the Yaesu side. That’s usually where space lasts longest.

Some banks have electronic availability displays nearby, which beats walking around. For anything oversized there are staffed baggage counters too, but their locations and hours change, so check the current station map before you head for a particular exit.

Shinjuku Station. The busiest station in the world, and the lockers act like it. There are banks near almost every exit. Sounds generous, until you notice the crowd finds them just as fast as you do.

In high season the large lockers are often gone by mid-morning. The New South exit area and the basement levels tend to hold out a little longer than the East side.

If you can spare five minutes, go one stop to Shinjuku-sanchome or Yoyogi. Your odds there are much better than on a second lap of Shinjuku.

Shibuya Station. Shibuya has been under redevelopment for years, so the lockers really do move around. A blog post from two years ago might send you to a bank that’s gone.

Go by the current station map, not old directions, and keep Ebisu or Harajuku as your fallback. Both are one stop away, and both are calmer.

Shinagawa Station. Underrated. It’s a major hub with a wide central concourse, but most people are changing trains here, not stopping, so its lockers get far less pressure than Shinjuku’s or Ueno’s.

If your day ends at Haneda, it’s the obvious pick anyway, since the Keikyu line runs straight to the airport from here.

Ueno Station. The park and museums bring in a lot of tourists, so the large lockers fill up early and stay full. The Park exit side goes first.

The usual workaround is Okachimachi, a short walk south.

Ikebukuro Station. Big, busy, and split into an East side and a West side with quite different personalities. Both have banks, and the two crowds rarely cross over, so if one side is full, walk through to the other before you give up.

A locker you can find in three minutes beats a cheaper one that takes twenty.

Attractions work the same way. Places like Tokyo Tower or the Shiodome complex usually have a few lockers of their own, but they’re sized for daypacks, not suitcases. Drop the suitcase at a station first, then go.

Where to look when everything is full

Honestly, this matters more than the prices.

At the busiest stations in peak season, every large locker can be taken by mid-morning. Standing in front of a wall of red “occupied” lights with a heavy suitcase is a very Tokyo kind of despair.

The fix: go one stop sideways.

Instead of Shinjuku, try a quieter station on the same line. Instead of Shibuya, ride one stop to Ebisu. Instead of Tokyo Station, look at Kanda or Yurakucho. Surprisingly often, five more minutes on a train gets you a whole wall of empty lockers.

Big stations also tend to have several locker banks, and travelers only ever find the first one. If the bank by the main gate is full, check near another exit, on another level, or next to the bus terminal outside.

Some lockers you can check before you go. JR East’s multiEcube lockers have a website showing live availability by size, and you can reserve one for a fee (check the current price on the official site). Not every station is covered and the display can lag, but a quick look costs nothing before you commit to a route.

One trap to know about: when a major international summit or meeting comes to Japan, railway operators have shut coin lockers at major stations for several days for security. If you’re arriving around dates like that, check station notices first.

The alternatives to lockers

When lockers don’t work out, or your bag really is too big for one, Tokyo has a decent backup list.

Staffed luggage storage counters are at major stations and at some department stores and tourist information centers. They cost more than a locker and you have to work around their opening hours, but they’ll take an oversized bag without any fuss.

Storage-sharing services like ecbo cloak let you book space in a café, shop, or hostel through an app, usually at a flat daily rate per bag. Coverage is good in central Tokyo and thinner in the suburbs. In high season, book the night before.

Your hotel or hostel will almost always hold guests’ bags before check-in and after checkout, for free. Hardly anyone thinks to ask. If you’re moving between two places on the same day, ask the one you’re leaving whether they’ll keep your bag until evening. They usually say yes.

Takkyubin, the same-day and next-day luggage delivery network, is the best trick for bigger moves. Instead of hauling a suitcase across the city, send it ahead to your next place and travel with a daypack. Convenience stores and hotel front desks can both arrange it.

A few habits that make this easier

Keep your passport, laptop, medication, and charger on you, not in the locker. That’s less about theft and more about flexibility. Plans change, and you don’t want to backtrack across two train lines for a cable.

Take a photo of the locker number and the station exit the moment you shut the door. Locker banks all look the same, and the stations are huge. This one habit has saved a lot of people a lot of walking.

See if your locker bank has a size chart posted. Most do, in centimeters, and reading it is quicker than trial and error with a suitcase in a crowded corridor.

If you’re traveling with something really big, like a bike box or a full-size instrument, assume lockers are out and plan on a staffed counter or a delivery service from the start.

FAQ

What size locker do I need for a suitcase?

Roughly, small fits a daypack or laptop bag, medium a cabin-sized carry-on, and large a checked suitcase. Most locker banks post a size chart in centimeters beside the doors, and it’s quicker to read that than to test doors with a suitcase in a crowded corridor. If your case is near the top of checked size, plan on a large locker or a staffed counter instead of hoping it fits.

How much do Tokyo coin lockers cost?

Small lockers generally cost in the low hundreds of yen per day and large ones a few hundred more, depending on the station and operator. Treat every figure you see online, that one included, as a rough guide, not a quote. The only price that’s actually true is the one on the locker panel.

Can I leave a bag in a coin locker overnight?

Usually yes, as long as you stay within the maximum, but expect to pay for two days, not one. The billing day generally resets at a fixed hour, 2 a.m. at most railway lockers, instead of running twenty-four hours from when you drop off, so eight hours overnight is normally billed as two days. The panel shows the maximum stay, commonly around three days.

Can I secure a locker the day before I need it?

Physically, yes, and people do it before a big travel day. Put something in, close the door, and the locker’s yours. Just remember you’re paying for the extra day, and the maximum-stay clock starts when you close the door, not when you come back.

What happens if I lose the key or my IC card?

For key lockers, go to the station staff office. For IC-card lockers, most panels have a way to get your things out with ID and the receipt code. One more reason to hang on to the printed slip if you get one.

Is it safe to leave a laptop in one?

Coin lockers in Japan have a strong safety record, and theft from them is rare. Still, most travelers keep their laptops with them, mostly because the hours your bag sits in the locker are exactly when you’ll want the laptop.
