Japan has spent decades building a reputation for remarkably clean, technologically advanced public toilets. Heated seats, bidet functions, deodorizing systems, ambient music, automatic lids and even voice controls have turned the humble restroom into something of a national calling card.
But Tokyo has taken the concept much further.
In Shibuya, public toilets have been transformed into architectural landmarks designed by some of the world’s best-known architects and designers. The project has become so popular that international visitors now deliberately seek out these toilets as part of their Japan itineraries.
And that creates an awkward problem.
A toilet is still a toilet.
It is supposed to be a practical public facility—not necessarily a tourist attraction where visitors gather with cameras while somebody is trying to use the bathroom.
The debate surrounding Tokyo’s unusual toilets raises a surprisingly important question about modern tourism: when does turning everyday infrastructure into an attraction stop being useful and start interfering with the people who actually live there?
The Tokyo Toilet Project
The story begins with THE TOKYO TOILET, a project that transformed 17 public restrooms in Tokyo’s Shibuya Ward.
The initiative was launched by The Nippon Foundation with the goal of creating public toilets that were cleaner, safer, more accessible and more welcoming to everyone, regardless of gender, age or disability. The project involved 16 prominent creators, including architects and designers such as Tadao Ando, Kengo Kuma, Shigeru Ban, Sou Fujimoto and Toyo Ito.
The project was never simply about making toilets look pretty.
Public restrooms can be neglected urban spaces. They can feel dark, unsafe, dirty or intimidating, which discourages people from using them.
THE TOKYO TOILET attempted to reverse that perception.
Instead of hiding these facilities away, the project treated them as part of the city’s public architecture.
That turned out to have an unexpected consequence.
People started visiting them on purpose.
The Transparent Toilet That Started the Conversation
Among the project’s most famous creations are the so-called Transparent Toilets.
Located at Yoyogi Fukamachi Small Park and Haruno Ogawa Community Park, these facilities were designed by architect Shigeru Ban.
From the outside, they look almost like glass boxes.
That immediately creates the obvious question:
“Wait… can people see you in there?”
The answer is supposed to be no.
The transparent walls use smart-glass technology. When the restroom is unoccupied, the glass remains transparent, allowing people outside to see the interior.
This serves a practical purpose.
Visitors can see whether the restroom is occupied and, importantly, can inspect the interior before entering. The transparency also addresses concerns about cleanliness and whether someone might be hiding inside.
Once the user locks the door, the glass becomes opaque, creating privacy.
On paper, it is an elegant solution to two traditional public-toilet problems:
privacy and security.
In practice, however, there is another problem.
When the Bathroom Becomes the Attraction
The Transparent Toilet was originally designed as public infrastructure.
It wasn’t intended to become a sightseeing landmark.
Yet its unusual appearance made it highly photogenic.
Tourists began photographing the building, and the restroom became part of Tokyo’s growing collection of unusual architectural attractions.
The Japan Today report highlighted an obvious problem: using the toilet can become embarrassing when visitors and passersby are standing around taking photographs.
Imagine needing to use a public restroom while several tourists are outside pointing cameras toward the building.
Even if the glass works exactly as intended, the psychological discomfort is real.
You might know the glass is opaque.
You might understand the technology.
But your brain still has that very reasonable reaction:
“I’m going to wait.”
And that is precisely where an attraction designed to improve public infrastructure can begin creating a new inconvenience.
The Technology Isn’t Perfect Either
Smart glass is clever, but clever does not mean flawless.
The Transparent Toilet reportedly experienced concerns during cold weather because the material responsible for changing the glass’s appearance could take longer to become opaque at low temperatures.
That raises an important point about public infrastructure.
A technology that works beautifully in a demonstration isn’t automatically ideal for something people depend on every day.
Public toilets need to work:
- in summer
- in winter
- during heavy rain
- at night
- when electricity systems malfunction
- when users don’t understand the controls
- when the facility is crowded
- when maintenance is required
A public restroom has a much higher standard of reliability than an architectural exhibition.
Nobody wants to discover that the futuristic privacy system has decided to have a bad day while they are inside.
Why Would Japan Turn Toilets Into Tourist Attractions?
At first glance, the entire concept sounds ridiculous.
Why would anyone travel halfway around the world to look at a public toilet?
But there is actually a broader cultural explanation.
Japan has long treated cleanliness, public order and hospitality as important parts of everyday life.
Public infrastructure is therefore capable of communicating something about the society that built it.
A train station tells visitors about transportation.
A convenience store tells them about retail culture.
A vending machine tells them about convenience and automation.
And a Japanese public toilet can demonstrate a surprisingly sophisticated combination of hygiene, technology, accessibility and design.
That makes these toilets more interesting than they initially appear.
Japan’s Toilet Culture Is Already a Tourism Phenomenon
Japan’s fascination with advanced toilets isn’t limited to Shibuya.
Japanese manufacturers such as TOTO and LIXIL have helped popularize high-tech toilets featuring heated seats, cleansing sprays, water-temperature controls and other functions.
For visitors accustomed to much more basic public restrooms, the experience can be genuinely memorable.
Japan’s toilet culture has even become a subject of museums and exhibitions. The TOTO Museum in Kitakyushu, for example, explores the history and development of Japanese toilet technology.
So the Shibuya toilets aren’t an isolated curiosity.
They are part of a larger Japanese story about how an ordinary household object became an example of engineering and design.
Then Came Perfect Days
The toilets received another unexpected boost from cinema.
Wim Wenders’ film Perfect Days, starring Koji Yakusho, follows a Tokyo public-toilet cleaner and uses Shibuya’s distinctive facilities as an important part of its setting.
The film brought international attention to the toilets and the people who maintain them.
The connection between cinema and tourism was immediate.
People who watched the film wanted to see the real locations.
Tokyo’s toilets suddenly had something normally associated with famous movie landmarks:
film tourism.
The phenomenon was strong enough to inspire organized toilet tours in Shibuya. Reuters reported that the Tokyo Toilet Shuttle offered visitors a two-hour itinerary featuring multiple redesigned public restrooms.
That sounds absurd until you remember that tourists already visit movie locations, architectural landmarks, cafés, shops and neighborhoods because they saw them on screen.
Why should a toilet be different?
The Toilets Were Never Supposed to Be Just Tourist Attractions
This is probably the most important detail to understand.
THE TOKYO TOILET project was fundamentally an urban-infrastructure and inclusion project.
The goal was to make public toilets comfortable for residents and visitors, including people of different genders, ages and abilities. The project’s official materials emphasize accessibility, with wheelchair access across the facilities and additional features such as ostomate facilities at some locations.
Tourism came later.
That distinction matters.
If the facilities become famous but local residents can no longer comfortably use them, the project risks undermining its original purpose.
A public toilet cannot be judged solely by how many Instagram posts it generates.
Its primary performance metric should probably be much less glamorous:
Can people use it comfortably when they need it?
The Local-vs-Tourist Problem
This isn’t unique to toilets.
It is a recurring problem in popular tourist destinations.
A local café becomes famous on TikTok.
A quiet street becomes an Instagram hotspot.
A neighborhood restaurant suddenly has enormous queues.
A traditional village becomes a day-trip destination.
A previously ordinary landmark becomes a must-see attraction.
Tourism brings money, jobs and global attention—but it can also bring crowds, noise, congestion and inconvenience.
The Transparent Toilet demonstrates this problem in miniature.
Visitors may see it as an architectural curiosity.
A resident may see it as:
“That’s the bathroom I use. Please stop taking pictures while I’m trying to get inside.”
Both perspectives are reasonable.
Why Public Toilets Are Particularly Sensitive
There is a special privacy issue involved here.
People expect to be photographed at a tourist landmark.
They don’t expect to become part of somebody else’s travel photography while entering a restroom.
Even if nobody is intentionally photographing individuals, cameras pointed toward a toilet can make users uncomfortable.
This is why tourist etiquette matters.
The fact that a building is interesting does not automatically mean everything happening around it is fair game for photography.
Visitors should avoid photographing people entering or leaving toilets, avoid blocking entrances and give users enough space to feel comfortable.
Common sense should not require a laminated instruction sheet.
The Bigger Lesson About “Instagrammable” Infrastructure
The Transparent Toilet illustrates an increasingly common phenomenon: ordinary infrastructure can become content.
Social media has changed the way people travel.
Previously, tourists mainly searched for:
- famous monuments
- museums
- temples
- castles
- natural scenery
Today, travelers also search for:
- unusual cafés
- vending machines
- themed restaurants
- convenience stores
- tiny streets
- manhole covers
- train stations
- public toilets
Anything visually distinctive can become a destination.
That can be beneficial.
It gives lesser-known neighborhoods exposure and encourages investment in public spaces.
But it can also create an attraction where none was intended.
Could Japan’s Toilet Tourism Actually Be Good for the City?
There is evidence that the concept has genuine tourism value.
A 2025 study by Takayuki Arima of Yokohama City University examined foreign visitors’ experiences with Shibuya’s designed public toilets. The research found that some international visitors remembered the toilets as “photo spots” or unexpected cultural experiences, although their influence on large-scale tourist flows was limited.
That is an important distinction.
The toilets probably aren’t going to replace Tokyo Tower or Senso-ji Temple anytime soon.
But they can create micro-tourism.
A visitor might travel to a part of Shibuya they otherwise wouldn’t have explored.
They may stop at a café.
They may walk through a park.
They may visit nearby shops.
They may discover a neighborhood outside the standard Tokyo itinerary.
That makes the toilets potentially useful as urban anchors.
The Architecture Is the Real Attraction
There is another reason the project works.
These aren’t merely expensive toilets with fancy buttons.
They are architectural experiments.
Each facility has a different identity.
Some are minimalist.
Some use striking geometric forms.
Others blend into parks and surrounding neighborhoods.
The project recruited globally recognized designers precisely because it wanted to challenge conventional assumptions about public toilets.
The result is closer to an outdoor architecture exhibition scattered throughout Shibuya than a conventional restroom upgrade.
In that sense, the toilets are not really the subject.
Design is.
The toilet simply happens to be the building type being redesigned.
Japan Has a Long History of Making the Ordinary Extraordinary
There is something very Japanese about this idea.
Japan has repeatedly demonstrated an ability to refine ordinary objects until they become remarkably sophisticated.
Consider:
- a simple knife becoming an exceptional piece of craftsmanship
- a basic train journey becoming a highly coordinated transportation experience
- a convenience store becoming a near-universal one-stop service center
- a simple meal becoming an art form
- a bathroom becoming a piece of architecture
The Transparent Toilet belongs to that broader tradition.
It asks a deceptively simple question:
Why does a public toilet have to be ugly?
And the answer is:
It doesn’t.
But Innovation Needs Restraint
There is also a danger in assuming that more technology always means better infrastructure.
A public toilet doesn’t need to become a science-fiction set.
The essential requirements remain surprisingly traditional:
cleanliness, privacy, safety, accessibility and reliability.
Everything else is secondary.
Smart glass is impressive.
Voice controls are impressive.
Heated seats are impressive.
Beautiful architecture is impressive.
But if someone cannot find the entrance, doesn’t understand the controls, worries about privacy or finds the restroom occupied by tourists taking photographs, the innovation has missed the point.
The best public design disappears into the user’s experience.
It works so naturally that people don’t have to think about it.
What Tourists Should Remember
Visitors who want to experience Tokyo’s famous toilets should remember that these are still functioning public facilities.
They are not museums.
There is no admission ticket.
People live and work around them.
Someone may genuinely need to use the restroom.
That means tourists should:
Don’t block entrances.
Don’t photograph people using or entering the toilets.
Don’t spend excessive time inside taking photographs.
Don’t treat local users as part of the attraction.
Respect accessibility facilities and priority users.
And perhaps most importantly:
Use the toilet if you need it.
You don’t have to turn every visit into a documentary.
The Future of Toilet Tourism
It is unlikely that Tokyo’s public toilets will suddenly become one of the world’s largest tourism industries.
And that isn’t the point.
Their real significance lies in what they reveal about modern cities.
A city is made up of more than its monuments.
Tourists experience transportation systems, sidewalks, parks, restaurants, convenience stores, public bathrooms and ordinary neighborhoods.
When those everyday spaces are designed well, they become part of the travel experience.
The Tokyo Toilet project demonstrates that infrastructure can simultaneously serve practical, social and cultural purposes.
But it also provides a warning.
Once an ordinary public facility becomes famous, the public’s relationship with it changes.
The challenge is maintaining the original purpose while accommodating the unexpected attention.
A Toilet Is Still a Toilet
The Transparent Toilet is a brilliant piece of design precisely because it solves a real problem in an unconventional way.
Its transparent walls help people see whether the facility is occupied and clean.
Its privacy system is designed to protect users.
Its architecture challenges the traditional image of the public restroom.
And its accessibility features reflect a broader ambition to make public facilities usable by more people.
But there is a delicious irony in its success.
The better the toilet became as an architectural attraction, the more difficult it could become to use it as… well, a toilet.
That is the strange future of tourism in the social-media age.
A place can be simultaneously:
public infrastructure, architectural art, cultural symbol, movie location and tourist attraction.
Japan’s transparent toilets prove that even the most ordinary parts of urban life can become globally famous.
They also prove something much simpler.
Sometimes the most important tourist attraction is the one you desperately need to use—but would prefer everyone to stop photographing.
And perhaps that is the ultimate lesson:
Good tourism should make a place more interesting without making it harder for local people to live there.
