TOTO Brings QR Code Restroom Maps and Live Queue Updates to Japan

A Phone Scan to Find a Less Crowded Restroom

TOTO, Japan's leading toilet manufacturer, launched a service in August 2025 that lets people scan a QR code to find nearby public restrooms and see how crowded they are. Called TOTO Connect Public, it brings information previously used by building managers directly to visitors trying to find an available toilet.

As of August 28, the service offers a practical response to a familiar problem at busy train stations and shopping malls: long restroom queues, particularly outside women's facilities. Visitors can check congestion, look for facilities with the features they need and report problems without having to find a member of staff.

The service works through a website, so users do not need to download an app. A QR code, the square pattern scanned with a smartphone camera, opens a map showing nearby restrooms and their live congestion levels. The displayed categories are vacant, slightly crowded and crowded.

Japan's growing urban populations and recovering tourism have increased pressure on public facilities. TOTO's approach is to make existing restrooms easier to locate and use, especially where some facilities have queues while others have space available.

Adding more toilets is not always straightforward. Older buildings and crowded city centers may lack room for extra plumbing or drainage. Giving visitors better information offers a way to ease bottlenecks without requiring major construction, although the service's value depends on people finding a suitable alternative nearby.

What Visitors Can Check Before Joining a Queue

QR codes placed at facility entrances or in public areas provide access to the restroom map. Visitors can use the congestion display to decide where to go before committing to a queue, rather than discovering a long wait only after reaching the entrance.

The website also lists restroom features, including wheelchair accessibility and the availability of high chairs for babies. For someone who needs an accessible facility or is caring for a child, the nearest restroom may be less useful than one equipped for their needs.

English, Chinese and Korean are available, extending access to international visitors as well as local users. Language support matters for both finding facilities and understanding the information shown on the website, particularly in unfamiliar stations or shopping complexes.

The service combines several tasks in one place: locating a restroom, checking its congestion and amenities, and contacting staff about a problem. A visitor can therefore choose a facility based on more than distance alone.

Reporting a Broken Flush or Missing Toilet Paper

A second QR code inside each stall allows users to report problems directly to facility staff. These can include a broken flush, an empty toilet paper dispenser or cleanliness concerns.

For visitors, the reporting function removes the need to leave the restroom and search for an attendant or reception desk. It also offers a less awkward way to flag an unpleasant situation, particularly when someone is unsure who is responsible for the facilities.

Facility staff receive the reports so they can respond promptly. The user facing service builds on internet connected management systems originally designed to tell building operators when a cubicle was dirty, supplies were running low or a toilet had been occupied for an unusually long time.

Pilot feedback was described as overwhelmingly positive. Participants welcomed being able to locate less crowded restrooms and report faults without the embarrassment or inconvenience of approaching staff. One unnamed participant in the pilot program described wanting a reporting feature during previous visits:

I wished for this kind of feature when encountering very dirty toilets in the past.

The comment points to a basic maintenance problem: visitors often notice something wrong before the next scheduled inspection. Giving them a direct reporting channel allows staff to learn about those problems sooner.

How Occupancy Monitoring Works

TOTO says the system uses sensors rather than cameras to determine whether facilities are occupied. The monitoring described includes sensors embedded in toilet seats or doors, with seat weight sensors and occupancy detectors identified as possible ways to detect use.

An occupancy sensor provides a simple signal about whether a space is being used. The system turns those signals into congestion information that visitors can understand without seeing the underlying technical data.

TOTO says the information is anonymized and used to display congestion levels and alert staff to maintenance needs. It also says no personal information is collected from people who scan the QR codes to view the restroom map or report a problem.

Privacy matters particularly in restrooms, where people expect a high degree of personal space. TOTO's stated approach is to monitor availability and maintenance conditions through sensors while keeping cameras out of the occupancy monitoring process.

Building managers can view combined usage statistics through a dashboard, a screen that brings information from multiple facilities together. This gives them a way to track demand and identify where attention is needed.

Why Women's Queues Are a Central Concern

Women often face longer waits for public toilets, especially at events, train stations and shopping centers. Higher demand and the time required for use contribute to the difference, alongside biological factors and the greater likelihood that women are accompanying children or older relatives who need assistance.

Long queues therefore affect more than the length of a visit. They can make moving through a busy station or shopping complex harder for people already managing care responsibilities. Information about alternative restrooms may help them choose a more practical route.

TOTO's service addresses the distribution of demand: where people go and whether they know another facility is available. The Japanese government is also pursuing measures that address how restroom space is allocated.

The Ministry of Land, Infrastructure, Transport and Tourism is seeking additional funding for digital signs displaying live restroom occupancy and movable toilet walls. The signs would help visitors assess queues before joining them, while movable walls would allow facilities to increase the number of stalls available to women during busy periods.

The ministry's funding request and TOTO's service tackle related parts of the same problem. Better information helps people use the facilities already available; flexible layouts allow operators to adjust capacity when demand changes. No funding amount or implementation date for the ministry's measures was given.

What Changes for Building Managers

Facility operators gain a centralized view of restroom conditions and usage. Instead of relying entirely on fixed inspection rounds or visitors finding staff in person, they can receive alerts and reports through the management system.

Usage patterns can help managers adjust cleaning schedules. A restroom that becomes busy at a particular time may need attention more frequently than one with lighter use. Reports about supplies or faults can also help staff decide where to go next.

Faster responses are expected to improve cleanliness and reduce the time facilities remain unavailable because of maintenance problems. Directing staff toward areas with greater need can also reduce wasted effort and support more efficient use of supplies.

Yoichi Nakayama, an official in TOTO's product sales promotion division, described the intended benefit for visitors. He said the service would:

enhance user satisfaction in a facility by enabling a more efficient use of restrooms.

TOTO's proposal is therefore as much about managing a building as helping an individual find a toilet. Visitor information, cleaning decisions and maintenance requests all draw on the same connected system.

Working Within Buildings That Cannot Easily Expand

Older buildings and dense urban areas create practical limits on restroom expansion. Adding cubicles may require changes to water pipes, drainage and the surrounding layout, making construction expensive or difficult.

TOTO Connect Public seeks to make existing capacity more visible. When visitors can see that one restroom is crowded and another has space, they have a chance to change their destination before spending time in a queue.

The approach also makes information about amenities easier to find. A person looking for wheelchair access or a parent needing a baby high chair can check those features alongside availability, rather than visiting several restrooms to inspect them.

For operators, combining that visitor information with maintenance monitoring offers a way to keep facilities usable for more of the day. A fault reported quickly can receive attention sooner, while cleaning schedules can reflect actual use.

How the Service Fits Japan's Toilet Technology

Japan is widely associated with toilets that offer heated seats, bidet functions and music to mask sounds. TOTO's Washlet bidet seats have become a recognizable example of that technology.

The QR service shifts attention from what happens at an individual toilet to the experience of finding and maintaining a public restroom. Comfort inside a cubicle has limited value to someone who cannot locate a suitable facility or faces a lengthy queue outside it.

Cleanliness also has a strong place in Japanese daily life, reflected in practices such as removing shoes indoors and maintaining public spaces carefully. Expectations for restroom hygiene sit within that wider cultural setting.

Public facilities have nevertheless faced pressures that advanced toilet fittings alone cannot solve. Crowded urban environments, aging infrastructure and increased tourism can strain both capacity and maintenance.

Japan's experience hosting major international events, including the Tokyo Olympics, also drew attention to accessible restrooms that visitors from different countries could use easily. Multilingual information and details about accessibility connect the new service to those practical needs.

A Broader Model for Managing Public Facilities

Other countries have experimented with restroom locator apps and digital signs. TOTO's approach brings live congestion information, language options and direct maintenance reporting into a connected service, linking the visitor's search with the operator's work.

Public toilets in many places remain difficult to find, poorly maintained or unsafe. Making availability and amenities easier to check can help people plan their movements, while a reporting channel gives them a way to flag conditions needing attention.

Cleaner, better maintained restrooms also support hygiene by reducing opportunities for germs to spread. For people with disabilities or other specific needs, timely information can make suitable facilities easier to locate.

Tourists may feel more comfortable exploring an unfamiliar city when they can find clean, accessible restrooms. Operators, meanwhile, can use maintenance and demand information to allocate staff and supplies more efficiently.

Urban services increasingly use connected technology to manage tasks such as traffic and waste collection. TOTO's initiative applies a similar idea to restrooms: collect information about conditions, make useful parts available to the public and help staff respond.

The practical outcome will depend on the day to day experience of visitors and operators. The service aims to shorten searches, direct people toward available facilities and speed up attention to faults, while government proposals address signs and flexible restroom layouts.
