Using a Japanese Coin Laundry: Every Button Explained

What you are looking at when you walk in

Most coin laundries have a row of front-loading washers, a row of dryers above or beside them, and one or more combined machines that wash and dry without you moving anything. There is usually a payment point, either a slot on each machine or a shared reader for cards and phone apps, and a wall of notices about opening hours, what may not be washed, and a contact number. Layouts differ, so read the machine in front of you rather than following a sequence you memorised elsewhere.

The good news for a learner is that the language barely changes. The same handful of kanji compounds appear on almost every panel, and the buttons are labelled with either those kanji or katakana borrowed from English. Once you can pick out washing, drying, cycle, time, start and finished, you can work out the rest by elimination, and the pictures printed beside each option usually confirm your reading.

The words on the machines

One pair is worth flagging. 洗濯 sentaku, washing, and 選択 sentaku, selection, sound identical, and both appear in a laundry: the machine washes and you select a cycle. The kanji differ and the context always makes it clear, so do not let the coincidence unsettle you when a screen says コースを選択 kōsu o sentaku, select a cycle.

Choosing wash, dry, or both

Decide first which machine you need, because that choice changes everything after it. A washer alone leaves you carrying wet laundry to a dryer, which is normal and usually cheaper in time. The combined machine runs the whole thing unattended, which suits a long errand but ties up the machine for far longer. The labels below are what you look for on the door and on the sign above the row.

Detergent and softener

Many washers add detergent and softener for you, and the panel says so with 自動投入 jidō tōnyū beside 洗剤 or 柔軟剤. When that label is present, adding your own can make too much foam, so leave it. Where the machine expects your own, there is a drawer or opening marked 投入口 tōnyūguchi, sometimes with separate compartments. Dryers never take detergent. If the notice is unclear, ask rather than guess, since the same shop may have both kinds of machine in one row.

Paying: coins, cards and apps

Older machines take coins in a slot on the front, newer ones use a shared payment station or a card and phone reader, and some shops run an app that starts the machine and tells you when it has finished. Machines differ even within one shop, so look for the slot, the reader symbol, or a screen before you load your laundry. A change machine, 両替機 ryōgaeki, is common but not guaranteed, and it may only accept certain notes.

Cycle names and how long they take

Cycles are usually shown as a short list with a time beside each one: a standard wash, a quick wash, and something for bulky items such as blankets. Dryers are normally sold in blocks of time rather than programmes, and adding more time part way through is often possible. The displayed minutes are estimates, so treat 残り時間 nokori jikan, time remaining, as approximate and come back a little early.

Drying temperature and what not to put in

Dryers usually offer a choice of heat, labelled 高温 kōon, 中温 chūon and 低温 teion, and the low setting exists for clothes that shrink or melt. Shops post notices about items that must not go in, and shoes and futons are the two that come up most often, because some shops have dedicated machines for them and others forbid them entirely. Read the notice above the row; the rules belong to that shop, not to coin laundries in general.

Start, lock and pause

Nothing happens until you press start, and on most machines the door locks the moment it does. That lock is a safety feature, not a fault, and it usually shows on the display as ロック中 rokku-chū. Some machines have a pause button that stops the drum and releases the door after a moment; many do not, especially once water is inside. Load everything you want washed before you start, because opening the door mid-cycle is often impossible.

Reading a status or error message

Error displays vary by machine, so learn the shape of the message rather than a list of codes. Most say a state and then an instruction: something is running, something is out of order, or something should be checked. If you cannot read it, the safest response is not to force anything. Photograph the display, note which machine number it is, and use the contact number on the wall, since the person answering can look up that code.

Asking an attendant or calling the number on the wall

Many coin laundries are unstaffed, and the wall carries a contact number for the management company. A phone call in Japanese is intimidating, so prepare three pieces of information before you dial: where you are, which machine, and what it is doing. Say them in that order and the rest of the call is mostly listening. If there is an attendant or a shop next door, the same three pieces work in person and you can point.

Sharing the room politely

• Come back near the finish time rather than leaving clothes sitting in a free machine.
• If a machine has finished and the owner is absent, wait a little before touching it, and if you must move the laundry, put it in the basket provided rather than on a surface.
• Wipe up spilled detergent and take your empty containers with you.
• Keep phone calls short and quiet; the room is small and sound carries.
• Do not sit on the folding table, which people use for clean clothes.
• Check the drum before and after your cycle for a stray sock, since forgotten items rarely find their owner.

Two notices are worth learning by sight. 放置 hōchi covers leaving things unattended and appears in requests not to abandon laundry, while 忘れ物 wasuremono means forgotten items and often points to a box or shelf where strays are kept. Neither is a rule you will be fined for, but both signal what the regulars expect.

Before your first visit, spend five minutes rehearsing. Read the table words aloud once, then cover the English column and read them again. Chant the six panel words in order: sentaku, kōsu, jikan, sutāto, unten-chū, shūryō. Practise the three-part problem report, where you are, which machine, and what it is doing, and say yukkuri hanashite itadakemasu ka until it comes out without a pause. Then photograph your local shop's panel and read one new label from it each day.
