Coin Laundry in Japan: How to Use One, What It Costs, and Washing a Futon

The short version

A wash typically runs about ¥200–¥1,000 depending on load size, and a 30-minute dry cycle is roughly ¥100–¥300 — both vary a lot by machine and neighborhood, so treat any number here as a starting estimate, not a receipt.
Some machines add detergent and softener automatically; others expect you to bring your own. There's usually no sign in English, so check for a detergent slot or a "no need to add" label before you buy a bottle you didn't need.
Cash still works everywhere, but a growing number of stores also take IC cards (Suica, Pasmo) or QR payment — don't assume either is available and have coins as a backup.
Most Japanese home washing machines don't dry. Pairing a home wash with a coin-laundry dryer, or drying everything on a rack, is the normal setup here, not a workaround.
Large coin-laundry dryers can usually handle a futon cover, a comforter, or a blanket that would never fit in a home machine — that's often the actual reason to go, even once you own a washer.

A shared-house private room, an older apartment with no washing machine hookup, or the gap between moving in and actually buying a machine — all of them land you at the same place: a coin laundry with instructions only in Japanese and a coin slot you're guessing at. None of it is complicated once you've done it once. The friction is just that nobody handed you the one-time walkthrough, so here it is.

Why you might not have a washing machine at all

This isn't always about being new to Japan. Share houses commonly put one or two washing machines in a shared laundry room rather than one per private room, which our guide to share houses in Japan covers from the contract side. Some older apartments have no washing machine hookup (bosui pan) at all, ruling out a home machine entirely. And even in a normal apartment, there's usually a gap of at least a few days between move-in and having a machine actually delivered and installed — our first-week moving-in checklist covers that timing. A coin laundry gets you through all three situations without buying anything.

Using the machines, step by step

From walking in to walking out with dry laundry

1 Pick a washer sized to your load Most stores have two or three washer sizes (roughly 8kg, 10-14kg, and a large 20kg+ machine for bulky items). Loading a small machine too full is the most common mistake — it won't clean properly and can trip the machine's sensor.
2 Check whether detergent is automatic Newer machines often have a "全自動" (fully automatic) label and a built-in detergent/softener dispenser — you don't add anything. Older machines have an open tray for you to pour your own liquid detergent into. If you're unsure, look for a detergent vending machine near the entrance; its presence is a hint that this store expects you to bring your own.
3 Pay and start the wash Coins go directly into a slot on the machine. Where a store has upgraded to card or QR payment, that's usually a separate reader mounted above or beside the machine, not the coin slot itself. A wash cycle is commonly 30–40 minutes.
4 Move wet laundry to a dryer Dryers are priced and started separately from washers, usually in set increments (for example, 100 yen per 10–12 minutes). Gas dryers, common in Japanese coin laundries, run hotter and faster than typical home dryers. Start with less time than you'd guess and add more if needed instead of running a full cycle up front.
5 Don't leave the store while machines run Unlike some countries, leaving to run errands mid-cycle is less common practice at Japanese coin laundries — stores are usually small, and someone else may want the machine the moment it finishes. Bring something to do and wait nearby.

What to do about a futon, comforter, or blanket

A standard home washing machine drum is too small for a futon, a winter comforter, or a large blanket, and even if it fit, the spin cycle wouldn't wring it out properly. This is where the large machines at a coin laundry earn their keep even after you've bought your own washer:

Look for the store's largest washer/dryer combo, usually rated 20kg or higher — sized for exactly this kind of bulky item, not everyday clothing.
A futon or comforter usually needs to run through both a wash and a full dry cycle at the large machine to come out usable — a single short dry often leaves it damp inside, which risks mold if you put it straight back into use.
Some futons (particularly traditional cotton-filled ones, as opposed to synthetic-fill comforters) are not machine-washable at all and specify dry cleaning or futon-specific cleaning services on their care tag — check the tag before loading anything expensive into a shared machine.
If nothing at your nearest coin laundry is large enough, or the care tag rules out a home wash, a futon dry-cleaning or futon-cleaning pickup service is the fallback — that's a separate service from a coin laundry and worth a quick local search rather than assuming one doesn't exist.

Buy, rent, or stick with the coin laundry

Buy your own machine

Makes sense once you know you're staying a while and your apartment has a hookup for one. Highest upfront cost, but no more coin-laundry trips for everyday clothes (a large item like a futon may still need a coin laundry's bigger machine).

Best if: you're staying 1+ years and your unit has a washing machine space

Rent a washing machine

Skips the upfront purchase and delivery wait in exchange for a monthly fee. Our comparison of furniture and appliance rental services covers the providers, minimum commitment periods, and cancellation terms.

Best if: you're staying under a year, or want a machine fast without buying

Coin laundry only

No upfront cost and no ongoing fee beyond what you use, at the price of a walk each time and no control over when a machine is free. Common in share houses or while waiting out a rental decision.

Best if: you're in a share house, undecided on how long you're staying, or just covering a gap

Where this guide stops

This page covers using a general-purpose neighborhood coin laundry — it isn't a directory of specific store locations or chains, since coverage and pricing vary too much by region to generalize into a single recommendation. It also isn't laundry-symbol care-tag interpretation beyond the machine-washable question above; for a garment with an unfamiliar care symbol, the safest default is to treat it as dry-clean-only rather than guess.

Two related guides worth reading alongside this one: what a share house's shared laundry room typically looks like before you sign a contract is in our share house guide, and the full first-week setup sequence, including the buy-vs-rent decision for furniture and appliances generally, is in our moving-in checklist.

This article provides general information only and is not a recommendation of any specific store, chain, or laundry-service provider. Prices, payment methods, detergent policies, and machine sizes vary by store and region and change over time; confirm what's posted at your nearest location before relying on the estimates above.
