Japanese at a Coin Locker: Sizes, IC Cards and Screen Prompts

Coin lockers let you drop your bags at a station and explore hands-free, and once you can read a handful of words on the door and the screen, they are quick and easy to use.

Japanese at a Coin Locker: Sizes, IC Cards and Screen Prompts

Japanese stations, airports, shopping centres and tourist spots have banks of koin rokkā, coin lockers. Older ones take coins and give you a key; newer ones are run from a touchscreen, take IC transport cards and give you a receipt with a PIN code. When the lockers are full or your suitcase is too big, a staffed counter, tenimotsu azukarisho, is the usual alternative. This guide walks through the whole process: finding a free locker, reading the sizes, following the screen, collecting your bag, and what to say when you lose the key or receipt or go over the time limit. Fees, time limits and payment options vary by operator and location, so always read the panel on the locker itself.

Look for kūshitsu or aki (free) and avoid shiyōchū (in use)

Touchscreen lockers usually print a receipt with a PIN code

Keep the key or receipt safe; you need it to take your bag out

Finding lockers and reading the signs

Station signs usually show a locker icon with the words koin rokkā, and larger stations have several banks near different exits. If you cannot see any, ask a station attendant. The word for a place to store luggage in general is nimotsu azukari, so either term will be understood.

Each locker door or the central screen shows whether a locker is free. The kanji to look for are 空 for vacant and 使用中 for in use. Some lockers show a green lamp for free and red for occupied, but the colours are not universal, so the words are more reliable.

Locker sizes and what fits

Lockers come in several sizes, usually labelled shō, chū, dai and sometimes tokudai, extra large. The size affects the price, and the fee for each size is usually shown next to the door or on the screen. The exact dimensions differ between operators, so measure by eye: a small locker takes a backpack or shopping bag, while a large suitcase may need the largest size or a staffed counter.

Some lockers show the inside dimensions in centimetres, with takasa for height, haba for width and okuyuki for depth. If your case is close to the limit, check before paying, because on touchscreen lockers the payment and locking often happen together.

小shōSmall: backpack, handbag

Coin and key lockers step by step

Classic lockers work with a key. You open an empty locker, put your bag in, close the door, pay the fee shown on the door and then turn and remove the key. The key tag shows the locker number, which you will need to find the locker again. Many coin-only lockers accept only 100-yen coins, so carry some change or use a nearby change machine, ryōgaeki.

If you want to take something out and put it back in, most coin lockers treat that as a new use, and you pay again when you close it. That is worth knowing if you plan to use the locker several times during the day.

JapaneseRomajiMeaning
扉を閉めてから料金を入れてください。Tobira o shimete kara ryōkin o irete kudasai.Close the door, then insert the fee.
百円硬貨のみ使用できます。Hyaku-en kōka nomi shiyō dekimasu.Only 100-yen coins can be used.
鍵を右に回して抜いてください。Kagi o migi ni mawashite nuite kudasai.Turn the key to the right and remove it.
両替機はどこですか。Ryōgaeki wa doko desu ka.Where is the change machine?
再度開けると料金がかかります。Saido akeru to ryōkin ga kakarimasu.Opening it again will cost another fee.

Touchscreen and IC-card lockers

Newer lockers are controlled from a central touchscreen, sōsa paneru, and many have an English button. If yours does not, the flow is short. You choose azukeru, to store, pick the locker number or size, put your bag in and close the door, then choose how to pay. After payment the machine prints a receipt, reshīto, with a PIN code, anshō bangō, or tells you to use your IC card to open it later.

To collect your bag, choose toridasu, to take out, and either enter the PIN, scan the barcode or QR code on the receipt, or touch the same IC card. If you have gone over time, the screen asks for the extra fee before the door opens.

レシートは大切に保管してください。Reshīto wa taisetsu ni hokan shite kudasai.Please keep your receipt safe.

Time limits and overtime fees

Most lockers charge by the calendar day rather than by the hour, so the day often changes at midnight or at another time shown on the locker. If you leave a bag overnight you may pay extra when you collect it. This extra is called chōka ryōkin or tsuika ryōkin, and paying it is seisan, settling the fare.

Lockers also have a maximum storage period, hokan kigen. After it, the operator usually removes the contents and keeps them somewhere else, and getting them back involves contacting the operator and paying the fees. The period depends on the locker, so read the panel if you plan to leave a bag for more than a day.

When something goes wrong

The most common problems are a lost key, a lost receipt, a forgotten PIN, a door that will not open or a locker that took your money. Each locker bank has a contact number, toiawase, printed on it, and station staff can usually tell you who manages the lockers, which may be the railway or a separate company.

Staff will ask for the locker number, roughly when you left the bag and what is inside, and they will usually ask to see identification before opening it. Keep your explanation short: what happened, which locker, and what you need.

JapaneseRomajiMeaning
ロッカーの鍵をなくしました。Rokkā no kagi o nakushimashita.I've lost my locker key.
レシートをなくしました。Reshīto o nakushimashita.I've lost the receipt.
暗証番号を忘れました。Anshō bangō o wasuremashita.I've forgotten the PIN.
扉が開きません。Tobira ga akimasen.The door won't open.
お金を入れたのに閉まりません。Okane o ireta noni shimarimasen.I put money in but it won't lock.
ロッカーの番号は25番です。Rokkā no bangō wa nijūgo-ban desu.The locker number is 25.
中身はスーツケースです。Nakami wa sūtsukēsu desu.Inside is a suitcase.
身分証明書はパスポートでいいですか。Mibun shōmeisho wa pasupōto de ii desu ka.Is my passport all right as ID?

Staffed baggage counters

When lockers are full or your luggage is too large, look for a staffed counter, tenimotsu azukarisho or nimotsu azukarijo. Major stations, airports and some tourist areas have them. Staff take your bag, give you a tag or receipt and tell you until what time you can collect it. Opening hours matter here, because unlike lockers the counter closes at night.

Some counters and services can also send luggage to your hotel or the airport, often called tebura kankō, hands-free sightseeing. Availability, prices and cut-off times vary, so ask at the counter.

JapaneseRomajiMeaning
荷物を預かってもらえますか。Nimotsu o azukatte moraemasu ka.Could you keep my luggage?
何時まで預けられますか。Nanji made azukeraremasu ka.Until what time can I leave it?
スーツケース一つです。Sūtsukēsu hitotsu desu.One suitcase.
この荷物をホテルに送れますか。Kono nimotsu o hoteru ni okuremasu ka.Can you send this luggage to my hotel?
預かり証をなくさないでください。Azukarishō o nakusanaide kudasai.Please don't lose your claim ticket.
荷物を取りに来ました。Nimotsu o tori ni kimashita.I've come to collect my luggage.

Locker etiquette and good habits

  • Do not store food that can spoil, valuables you cannot replace, or anything dangerous; lockers usually list prohibited items.
  • Close the door gently and check it is locked before you walk away by pulling it lightly.
  • Note the exit name as well as the locker number, since large stations have many banks of lockers.
  • If you are travelling as a group, one large locker is often cheaper than several small ones.
  • Collect your bag before your storage period ends so that it is not removed.

The two verbs that run the whole system are azukeru, to leave in someone's care, and toridasu, to take out. Once you recognise them, almost every locker screen and baggage counter in Japan becomes easy to follow.

Key points

A practical way to improve

Say the steps of using a locker aloud in Japanese: find a free one, choose the size, pay by IC card and read back the PIN on the receipt. Then ask the AI Sensei in Unihongo's immersive 3D classroom to play a station attendant while you explain that you have lost your locker receipt and need your suitcase. Describe the locker's location, its size and roughly when you left the bag. The Report a Lost Wallet mission is good follow-up practice, since it uses the same skills of describing an object, a place and a time to staff.

  1. 1

    Choose one clear goal

    Focus each session on a situation or skill you can actually use.

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

How do I find a free coin locker in Japan?

Look for the green light or the word aki or kūshitsu on the screen or door, which means vacant. A red light or shiyōchū means in use. At busy stations, lockers fill up early in the day, so it is worth checking lockers in a less busy exit or using a staffed baggage counter.

Can I pay for a coin locker with an IC card?

Many newer lockers accept transport IC cards, and some accept other cashless payments, but older lockers take coins only, often just 100-yen coins. The payment options are shown on the locker panel. Some IC-card lockers use the card itself as your key, so you need the same card to open it.

How long can I leave luggage in a coin locker?

Time limits and fees vary by operator. Many lockers charge per calendar day and allow a limited number of days, after which your items are removed and stored elsewhere. The rules are printed on the locker, so check them before you leave your bag overnight.

What should I do if I lose my locker key or receipt?

Call the number printed on the locker or ask the station staff. Say kagi o nakushimashita or reshīto o nakushimashita. You will usually need to show identification and describe the contents before the locker is opened, and there may be a fee.

What is tenimotsu azukarisho?

It is a staffed baggage storage counter, found at many large stations, airports and tourist areas. Staff take your bag and give you a tag or receipt. It is useful when lockers are full or your suitcase is too big for the largest locker.
