What kind of property can you open a coin laundry in? Use zoning, drainage and utilities

In short: the property for a coin laundry is first narrowed down by use zoning. An unmanned coin laundry — where customers wash their own clothes and no laundry is received or delivered — is usually treated under the Building Standards Act as a "service-industry shop" where it mainly serves the neighbourhood, but where the motor output of the commercial machines is large it can be treated as a "factory," in which case it cannot be built in residential-only zones. Beyond zoning, a property gets stuck on water supply and drainage, electrical and gas capacity, and preventing lint (fibre-dust) fires in the dryers. An unmanned laundry itself is outside the Cleaning Business Act, but adding a cleaning agency (a drop-off/pick-up counter) triggers a notification under that Act (Article 5(1)). Final confirmation rests with the specified administrative authority, the public health centre and the local fire department.

This is for owners and investors weighing a coin laundry as an investment or diversification in a vacant ground-floor tenancy or former shop. Drawing on the Building Standards Act, City Planning Act, Cleaning Business Act, Water Pollution Control Act and Fire Service Act, and on national and municipal materials, it sets out what you can confirm when choosing a property. What we handle is finding the property and the explanation of important matters; this article stays on the property-side requirements — zoning, drainage, electrical capacity and the like.

Which use zone can a coin laundry open in?

Use zones are the area classifications set by Article 8(1)(i) of the City Planning Act — thirteen in all. What may be built in each is set by Article 48 of the Building Standards Act and its Appended Table 2. The feasibility of a coin laundry turns on which use in that table it is read as.

The national (former Ministry of Construction) treatment is that a coin laundry, where it mainly serves nearby residents, is generally handled as one of the "clothing shops, tatami shops, joinery shops, bicycle shops, household-electrical-appliance shops and other similar service-industry shops" in Appended Table 2 (operation of use zoning is governed by notices such as "Enforcement of the Act partially amending the City Planning Act and the Building Standards Act," Notice No. 225 of 25 June 1993. Accessed 18 September 2026). Where the motor output of the commercial washers and dryers is large, or many machines are installed, some authorities treat it as a "factory using a prime mover," which tightens the restrictions a step.

How it is read under the Act	Use zones where it cannot open (in principle)	Note
Service-industry shop	Category 1 low-rise residential zone (floor-area, etc. limits)	Possible by scale in Category 2 low-rise and above
Factory using a prime mover	Category 1 / 2 low-rise and Category 1 / 2 medium-high-rise residential zones	Quasi-industrial / industrial zones tend to suit

Whether the same coin laundry is read as a shop or a factory depends on the specified administrative authority (the municipal building official). Some authorities draw the line by the combined output and number of prime movers, so confirm the treatment with the authority for the location before you sign. Use zones can be checked on the map in MLIT's "Real Estate Information Library." How zoning works when opening a restaurant from a bare shell is set out in opening a restaurant in a skeleton property.

How do the procedures differ between an unmanned laundry and a cleaning agency?

Within the same premises, "an unmanned laundry where customers wash their own clothes" and "an agency that takes in and hands back laundry" are treated quite differently in law. Confuse them and you miss a required notification.

Article 2(1) of the Cleaning Business Act (Act No. 207 of 1950) defines "cleaning business" as making a business of washing clothing and the like in its original form using solvent or detergent; Article 2(2) includes among "operators" those who make a business of receiving and handing back laundry without washing it. To open a "cleaning establishment" under Article 2(4), Article 5(1) requires prior notification to the prefectural governor. As a rule, at least one cleaning technician must be placed at each establishment, but agencies that only receive and hand back laundry are excepted (Article 4(1)).

By contrast, an unmanned coin laundry where customers wash their own clothes is called a "coin-operated cleaning business" and is not regulated by the Cleaning Business Act. Because the public shares the machines, however, following the national "Guideline on Hygiene Measures for Coin-Operated Cleaning Business Facilities" (Notice Kan-shi No. 39 of 29 March 1983), many municipalities require, by their own guidelines, an opening notification and an on-site check.

Form of the shop	Basis	Notification	Cleaning technician
Unmanned laundry (self-service)	Coin-operated cleaning business	Opening notification under a municipal guideline (not a statutory duty)	Not required
Cleaning agency added (takes in laundry)	A cleaning establishment under the Cleaning Business Act	Opening notification under Article 5(1) (prefectural governor)	Not required for an agency (Article 4(1))

Whether you add an agency changes the procedures required. Preparing and submitting the cleaning-establishment opening notification is the work of an administrative scrivener. We (real estate) handle finding the property and the explanation of important matters; the notification goes to an administrative scrivener — each engaged by you directly.

For drainage and water-quality rules with gas dryers and boilers, where do you look at the property?

A coin laundry uses a lot of water, so it cannot open where the property's water-supply and drainage capacity does not match. You look at three things: piping that can handle the supply and discharge volume, whether it can connect to the sewer, and whether the discharge runs into water-quality rules.

An ordinary coin laundry that only uses water is not usually a "specified facility" under the Water Pollution Control Act (Act No. 138 of 1970). Notification as a specified facility (Article 5) is required for washing facilities that use solvents such as tetrachloroethylene in dry cleaning. If you add a dry-cleaning machine, confirm at the design stage whether it falls under a specified facility in Appended Table 1 of the Order. Where you discharge to the sewer, you must meet the discharge standards of the Sewerage Act (Article 12-2, etc.), and discharge containing oils or fibre debris may require treatment equipment.

What to confirm	What to look at	Where to check
Water supply / drainage capacity	Pipe diameter that can handle simultaneous running of the machines	Architect / equipment contractor
Sewer connection	Connection to public sewer; discharge standards (Sewerage Act)	Municipal sewerage division
Water-quality rules	If a dry machine (solvent) is added, is it a specified facility under the Water Pollution Control Act	Municipal environment division / equipment contractor

The drainage route and the water-quality and equipment design where gas dryers and boilers are used are the province of the equipment contractor and architect. We organise the property's existing water-supply and drainage situation and the feasibility of sewer connection, and hand off to the equipment contractor and architect.

For electrical capacity, gas and fire prevention (lint fires), what equipment must you confirm?

The machines draw a lot of power and gas, and the dryers carry a fire risk. At the property you confirm the three-phase 200 V (power) service and contracted capacity, the gas supply type and capacity, and fire and disaster prevention.

Commercial washer-dryers often run on three-phase 200 V (power), and the existing service or contracted capacity may fall short; increasing it requires coordination with the power company and an electrician. For a gas dryer, confirm the gas supply type (city gas / LP gas) and capacity. On fire prevention, an unmanned coin laundry is generally in item (15) of Appended Table 1 of the Order for Enforcement of the Fire Service Act (a "business establishment not falling under any of the preceding items"), and fire extinguishers and the like are required by scale. In addition, the position, structure and management of fire-using equipment such as gas dryers and boilers are set by the municipal fire-prevention ordinance based on Article 9 of the Fire Service Act.

Equipment	What to confirm at the property
Electricity (power)	Three-phase 200 V service and contracted capacity; feasibility of increase
Gas	Supply type (city gas / LP gas) and capacity
Fire prevention (extinguishers, etc.)	Item (15) of Appended Table 1 = other business establishment
Fire-using equipment	Position and structure of gas dryers and boilers (Article 9; municipal ordinance)

Easily overlooked are lint (fibre-dust) fires in dryers. Ignition of lint built up in dryer ducts and lint filters has been a cause of past fires. In unmanned operation it is discovered late, so regular cleaning of ducts and lint filters, and prior consultation with the fire department, are the key points. Whether extinguishers and the like are needed is decided by the local fire department; consulting before work starts avoids re-doing it.

Does searching for a fitted-out or a bare-shell property change the total cost?

A coin laundry carries large upfront costs for machines and construction, and the total varies greatly with the state of the property. Rather than the gross yield alone, think through the costs and the time to ramp up.

A fitted-out property that was previously a coin laundry may retain the base for water/drainage, power, gas and exhaust, sometimes keeping construction costs down. A bare shell offers more freedom but needs water/drainage, power service, exhaust ducting and fire-prevention work from scratch, and a change-of-use confirmation may be required. Whether that confirmation is needed turns on the floor area of the part put to the use, and the judgement is the province of the architect and the designated confirmation and inspection body. When converting a used property without a certificate of inspection, the approach in can a used property without a certificate of inspection be converted to a welfare facility is a useful reference.

How you search	What tends to help	Watch-outs
Fitted-out former coin laundry	Base for water/drainage, power, exhaust remains	Machine condition and service life; non-conforming existing building
Fitted-out other trade / bare shell	Freedom of location and layout	Power, gas, exhaust and fire-prevention work from scratch

Because the numbers vary greatly by property and area, we do not assert a specific yield; we set out the breakdown of costs and how to think about vacancy and low-occupancy risk. The overall picture of finding commercial property and investing is at investment and commercial property consultation, and property consultation for opening a business at commercial property consultation. Consultation is free. For warehouse-use property requirements, where can you open a trunk room is also a useful reference.

The division of roles is as follows. Investigation, valuation and brokerage of the property and the lease are undertaken by Yotsuba Real Estate Co., Ltd. (licensed real estate agent, Tokyo Governor (1) No. 113304). The cleaning-establishment notification where an agency is added goes to an administrative scrivener; water/drainage, gas and exhaust design to an equipment contractor and architect; the change-of-use confirmation to an architect and the designated confirmation and inspection body; whether fire equipment is needed to the local fire department; and the tax of opening to a tax accountant — each consulted or engaged by you directly. These are each independent business entities. You engage each one directly. We neither accept nor pay referral fees or introduction commissions.

Frequently asked questions

Q. To open an unmanned coin laundry, do I need a notification under the Cleaning Business Act?
A. An unmanned coin laundry where customers wash their own clothes (a coin-operated cleaning business) is outside the Cleaning Business Act, so no cleaning-establishment opening notification under that Act is required. However, many municipalities require, by their own guideline, submission of a "coin-operated cleaning business facility opening notification" and an on-site check. Confirm with the public health centre for the location before opening. If you add an agency that takes in laundry, a separate notification under Article 5(1) of the Cleaning Business Act is required.

Q. Can I run a coin laundry even in a ground-floor tenancy in a residential area?
A. It depends on the use zone and on whether it is read under the Building Standards Act as a "shop" or a "factory." If the combined output and number of the machines' prime movers make it a "factory," it cannot in principle be built in Category 1 / 2 low-rise residential or medium-high-rise residential zones. Even where it is read as a shop, floor-area and other limits apply in residential-only zones. Because the line depends on the authority's operation, confirm it before you sign.

Q. Are there special rules on a coin laundry's drainage?
A. An ordinary coin laundry that only uses water is not usually a specified facility under the Water Pollution Control Act. What falls under a specified facility is, for example, a dry-cleaning washing facility using solvents such as tetrachloroethylene. The treatment changes with whether you add a dry machine. Where you discharge to the sewer, you must meet the Sewerage Act's discharge standards, and discharge containing fibre debris or oils may need treatment equipment. Confirm the design with the equipment contractor and architect.

Q. How do I prevent dryer fires?
A. Ignition of the fibre dust (lint) built up in dryer ducts and lint filters is the main cause. In unmanned operation it is discovered late, so regular cleaning of ducts and lint filters is the key point. The position, structure and management of fire-using equipment such as gas dryers and boilers are set by the municipal fire-prevention ordinance based on Article 9 of the Fire Service Act. Confirm whether extinguishers and the like are needed with the local fire department, and consult before work starts.
