There is a simple order for getting your laundry done at a hotel: 1) the in-house coin laundry → 2) drying in your room (hand-washing and the bathroom dryer) → 3) an outside coin laundry or a pickup-and-delivery cleaning service. Follow it and you will not get stuck. Most major business hotel chains have an in-house laundry, and their official sites state prices in the range of free to ¥600 per wash, and free to ¥100 per 20–30 minutes for the dryer (as of August 2026, confirmed by our editorial team on each chain’s official pages). This article covers how to find the in-house laundry and what it costs, the steps and etiquette for drying clothes in your room, where the line falls for sending laundry out, and how many changes of clothes to pack by length of stay — all as the practical routine of a stay.

Finding the in-house coin laundry and what it costs (five major chains, confirmed on official sites)

There are three stages to finding one. Before you book, look at the “in-house facilities,” “amenities” and “services” fields on the individual hotel page of the official site. The number of machines, the floor they are on and the prices are usually listed on the page for the specific hotel rather than on the chain-wide page; Dormy Inn (ドーミーイン) and Route Inn (ルートイン) go as far as listing prices by machine type on their “in-house guide” and “other facilities” pages. After you arrive, check the in-room TV guide and the front desk for the floor and how busy it is. Before you use it, confirm how detergent is handled (automatic dispensing, free supply, sold at the front desk, or bring your own) so you do not have to walk back from the laundry room. If you want to shortlist hotels by their laundry facilities from the moment you start choosing, the amenities field on each property page is the fastest filter.

The table below records what could be confirmed on the official sites of the five major chains in August 2026. Prices differ by property, so the figures in the table are examples of properties whose prices are stated on the official pages. They are not presented as a general market rate.

Here is how to read the table. If you want to wash empty-handed, without carrying detergent, Dormy Inn with its automatic dispensing and Super Hotel with its free detergent save you a step. If you want to wash a full load at once, a property like Route Inn Tokyo Asagaya, with front-loaders that wash and dry in a single cycle, suits you better. Suits and jackets should not go in a domestic machine; the safe route is the cleaning service, as at APA Hotel, where a laundry bag and slip are already in the room. If your stay runs beyond a week, another option is a stay-type hotel with a washer-dryer in the room. Properties with in-room washer-dryers, such as Tokyu Stay (東急ステイ), are covered concretely in Five long-stay hotels next to major hospitals with late-night entry (innippon, in Japanese).

Steps and etiquette for drying clothes in your room (bathroom dryer, hangers, quick-dry fabrics)

For underwear, socks and T-shirts, you can finish everything in the room without going to the laundry. There are five steps.

1. Press-wash in the basin: dissolve travel detergent (single-use sachets are convenient) in lukewarm water and press-wash for two to three minutes. Soak heavily soiled collars and underarms for about 15 minutes first.
2. Rinse until no more suds appear: detergent left in the fabric causes odour once dry, so rinse at least twice.
3. Blot with a towel: wringing causes creases and misshaping. Press the garment between bath towels to transfer the water. If you are unsure about using one of the room’s towels for this, just ask the front desk for a replacement — that is no problem.
4. Hang in the bathroom: hang hangers on the shower curtain rail or towel bar of the unit bath and leave the extractor fan running. In a room with a bathroom dryer, things dry in one to two hours.
5. Finish with a hairdryer: aim warm air at the thick parts only — underarms, collars, seams — keeping the dryer moving. Holding it on one spot causes shrinkage and fading.

Three lines of etiquette to keep: do not tie a line to the walls, furniture or light fittings in the room (marks and damage are chargeable), do not put wet clothing on the floor or the bed, and do not hang anything outside the window. Most hotels provide only two or three hangers in the room, so two or three folding hangers and a suction-cup laundry line give you enough hanging space inside the bathroom alone. For fabrics, quick-dry polyester base layers and quick-dry socks dry overnight, while a heavy 100% cotton T-shirt can still be damp the next morning when dried indoors.

Where the line falls for using an outside coin laundry or a delivery cleaning service

The situations the in-house laundry and room drying cannot cover come down to three things: how much, what kind of clothing, and how soon.

• By volume: in-house washers are mostly domestic-sized. For loads over 10 kg at a time — a family’s washing, or a sports training camp — and for bulky items such as blankets and sleeping bags, a neighbourhood coin laundry with large machines finishes the job in one go. When the in-house machines are busy in the evening and a queue forms, going out can also be faster.
• By type of clothing: suits, jackets, coats, leather goods and anything labelled not washable cannot go in a domestic in-house machine or a neighbourhood coin laundry. Use the hotel’s cleaning service (put the items in the room’s laundry bag and take it to the front desk) or a pickup-and-delivery cleaner.
• By timing: hotel cleaning services generally return items the next day at the earliest, and pickup-and-delivery cleaners need at least about two days from collection to return. Send what you will wear tomorrow to the in-house laundry or dry it in the room, and send what you will wear three or more days from now out — split it that way and you will not be caught short. Check in advance with both the front desk and the operator whether the delivery cleaner can use the hotel as the delivery address.

On cost, one in-house cycle (wash plus dry) generally comes in at a few hundred yen, whereas the cleaning service is priced per garment. For the total cost of a stay including laundry, and the things that trip people up about hotel living, see 6 Downsides of Hotel Living in Japan: ¥502,000 per 30 Nights & Fixes. A head-to-head comparison of the washing methods themselves — coin laundry, hotel laundry service, delivery cleaning and hand-washing — is a separate question; what this article adds is the routine and the number of garments.

How many changes of clothes to pack by length of stay

Once the laundry routine is settled, the number of garments to bring can be worked back from “days until the next wash + one day of drying.” Below are one-person guidelines for two patterns: using the in-house laundry (washing every two to three days) and room drying only (hand-washing a small amount every night).

Compiled by the HotelBank Editorial Team. One person; dress shirts and suits are counted separately (on the assumption they go to the cleaning service).

The key point is not to add garments past seven nights. Clothes beyond seven nights’ worth only eat into the volume and weight of your suitcase; fixing the wash cycle to set days — “every two days,” “twice a week” — cuts both luggage and effort. On stays longer than two weeks, the round trip to the in-house laundry becomes a cost in itself, which is the point to switch to a stay-type hotel with an in-room washer-dryer, or to a hotel with a monthly plan. For the night count at which the rate starts to fall, Japan Hotel Long-Stay Discounts: 15% at 7 Nights, 20% at 30 Nights has the measured figures.

Frequently asked questions

How much does a hotel’s in-house coin laundry cost?

Among the properties whose prices are stated on the official sites of the five major chains, washers ran from free to ¥600 per load and dryers from free to ¥100 per 20–30 minutes (as of August 2026). Some Dormy Inn properties explicitly list the washer as a free service; Super Hotel Sendai Hirosedori charges ¥200 per wash with the dryer and detergent free; and Route Inn Tokyo Asagaya charges ¥200 per load for top-loaders and ¥600 for front-loaders. Prices differ from property to property even within the same chain, so check the individual page of the hotel you are staying at.

Do I need to bring detergent?

It depends on the chain. Dormy Inn dispenses detergent automatically (free) and some Super Hotel properties supply it free, so you can wash empty-handed. Route Inn sells it at the front desk or a vending machine for around ¥50 a sachet, and you may bring your own. Toyoko Inn and APA Hotel handle it property by property, so the reliable move is to ask at the front desk after you arrive. If you are hand-washing in the room, individually wrapped single-use sachets mean nothing goes to waste.

Am I allowed to dry laundry in my room?

Drying inside the bathroom is fine, but keep to three lines: do not tie a line to the walls, furniture or light fittings in the room (marks and damage are chargeable), do not put wet clothing on the floor or the bed, and do not hang anything outside the window. Many rooms provide only two or three hangers, so two or three folding hangers and a suction-cup laundry line give you enough hanging space inside the bathroom alone.

How long does laundry take to dry in a hotel room?

In a room with a bathroom dryer, one to two hours is the guide. In a bathroom with only an extractor fan, quick-dry polyester base layers and quick-dry socks take overnight, while a heavy 100% cotton T-shirt can still be damp the next morning. Blot the water out between bath towels before hanging, and aim a hairdryer’s warm air at the thick parts only — underarms, collars, seams — to speed things up (holding it on one spot causes shrinkage and fading).

How many changes of clothes should I take on a one-week business trip?

Assuming you use the in-house laundry every two to three days, the guide for 7–13 nights is four to five sets of underwear and socks, five tops and two to three bottoms. If you hand-wash nightly and dry in the room, you can cut that to three sets of underwear and socks, three to four quick-dry tops and two bottoms. The count works back from “days until the next wash + one day of drying,” and past seven nights, fixing the wash cycle at twice a week cuts luggage and effort more than adding garments does.

About the data

■ Data sources

The treatment of washers, dryers and detergent at the five major chains (Dormy Inn / Super Hotel / Toyoko Inn / APA Hotel / Route Inn) was confirmed by the HotelBank Editorial Team on 21 August 2026 by reading the service guide pages and the individual hotel pages on each chain’s official site. Prices, machine counts and the floor they are on differ by property, so the figures in the tables above are examples of properties whose prices are stated on the official pages, not chain-wide prices. The turnaround for delivery cleaning and the capacity of outside coin laundries are general operating guides.

■ Calculation assumptions

The number of changes of clothes by length of stay was worked back for one person, treating “days until the next wash + one day of drying” as the required count, for two patterns: (1) using the in-house laundry every two to three days, and (2) hand-washing a small amount nightly and drying in the room. Garments sent to the cleaning service, such as dress shirts and suits, are not included in the counts. Drying time is taken as one to two hours in a room with a bathroom dryer and overnight in a bathroom with only an extractor fan.

■ Limitations and caveats

Prices and machine counts are the official statements at the time of access and change with renovations, equipment replacement and price revisions. Check the page of the property you are staying at before you book. Washer capacity, drying time and how detergent is supplied vary widely between properties within the same chain, so the figures here cannot be treated as a general market rate. The guide for changes of clothes is per person and shifts with temperature, how much you perspire and the dress code where you are travelling. Whether and how far you may hand-wash and dry clothes in the room is governed by each hotel’s terms of use and in-house guide.
