Visitors to Japan often ask the same question:
“Why are the streets so clean when there are so few trash cans?”
There is relatively little litter on the streets and in parks, graffiti is uncommon, and many visitors are surprised by how clean train stations and public restrooms are.
Of course, Japan is not perfectly clean everywhere. Many cleaning and maintenance staff work hard every day to keep stations, public facilities, and other shared spaces in good condition.
But if you look at everyday life in Japan, you will also find many habits that help prevent places from becoming dirty in the first place: keeping outside dirt outside, putting things back after using them, and not leaving your mess for the next person.
To understand where some of these habits come from, it helps to begin with an old Japanese idea: purification.

The Long-Standing Japanese Idea of Purification
When visiting a Shinto shrine, you will usually see a water basin near the entrance. Before approaching the main shrine, visitors rinse their hands and mouth.
This practice is connected to the Shinto concepts of kegare—a state of impurity—and misogi or harae, forms of purification.
This does not mean that Shinto explains why people in modern Japan do not litter.
However, practices involving cleansing the body or preparing oneself before entering a particular place have existed in Japan for centuries.
Even in everyday life today, you can find clear boundaries between places where dirt is acceptable and places people try to keep clean.
The Japanese home is a good place to see how this works.
Inside the Home: Small Boundaries That Keep Dirt Out
The Genkan: Where “Outside” Becomes “Inside”
The genkan, or entranceway, marks the boundary between outside and inside a Japanese home.
There is usually a lower area where you stand in your outdoor shoes and a raised area that you step up onto after removing them.
This simple arrangement helps prevent dirt, dust, and mud from outdoor shoes from being carried into the living space.
You will encounter the same custom in many other places in Japan, including traditional inns, temples, some restaurants, and certain public facilities.
For international visitors, taking off your shoes may become one of the most familiar habits you encounter during a trip to Japan.
Why Are There Separate Slippers for the Toilet?
Even after taking off your outdoor shoes, you may find another pair of slippers waiting inside the toilet.
In homes where toilet slippers are provided, they are worn only inside the toilet. The idea is to avoid carrying dirt from the toilet floor into hallways and other living spaces.
When you leave, the toilet slippers stay there and you change back into your regular indoor slippers.
So even after the larger boundary between “outside” and “inside” has been crossed, there may be smaller boundaries within the home.
Tatami Rooms: Why Even Slippers Come Off
When entering a tatami room, indoor slippers are usually removed as well.
For Japanese people this feels completely normal, but international visitors may wonder: “I already took off my shoes. Why do I have to take off my slippers too?”
People sit and sometimes lie directly on tatami, so it is a surface that regularly comes into contact with the body. Removing slippers helps keep it clean and also protects the delicate surface from damage.
Tatami rooms also reveal another interesting part of traditional Japanese life: the habit of putting things away.
For generations, a single Japanese-style room could serve different purposes at different times of day—eating, relaxing, receiving guests, or sleeping. Some households still live this way today.
At night, futons may be spread across the tatami. In the morning, they are folded and stored in a closet so the room can be used again during the day. A traditional low dining table could likewise be put away after a meal.
When the same room has several uses, it has to be reset before it can serve its next purpose.
This kind of daily routine may be one reason why “put it away when you are finished” and “return the space to a usable condition” have long been familiar habits in Japanese homes.
Bathing: Wash Before You Enter the Tub
Japanese bathing follows a similar principle.
Whether at home, at a public bath, or at an onsen, people wash their bodies before entering the bathtub.
The bathtub itself is not where you scrub off dirt. You wash first, then soak.
At home, family members may share the same bathwater. At an onsen or public bath, many people share the same bath. Washing first helps keep the water clean for everyone.
From the genkan to the toilet, tatami room, and bath, Japanese homes contain several small boundaries designed to keep dirt from moving into cleaner spaces.
At School, Children Clean the Spaces Everyone Uses
Many Japanese schools have a designated cleaning time.
Students do not clean only their own classrooms. They may also be responsible for hallways, staircases, entrance areas, shoe lockers, special classrooms, and other shared parts of the school. At some schools, students also clean the toilets themselves.
They sweep floors, wipe surfaces with cloths, straighten desks and chairs, remove sand and dust from shoe areas, and put the cleaning equipment away when they finish.
Children repeat these routines for years during their school life.
What is especially interesting is that students are not limited to cleaning places they personally made dirty.
A child may clean a hallway they barely used that day, or an entrance and classroom shared by many other students.
From a young age, they repeatedly experience the idea that keeping a shared space clean is something they themselves take part in.
School cleaning alone cannot explain why Japanese streets are clean. But spending years cleaning and organizing shared spaces may influence how people later behave in public places.
“Leave the Place Clean When You Go”
Japan has a proverb:
Tatsu tori ato o nigosazu
(立つ鳥跡を濁さず)
Literally, it refers to a bird leaving without muddying the water behind it. One of its meanings is that when you leave a place, you should leave it clean and in good order.
At school events, camps, sports activities, and other group outings, people may also hear the phrase:
“Leave it cleaner than you found it.”
The idea is simple: put things back, pick up any trash, and if possible leave the place a little cleaner than when you arrived.
This way of thinking appears in many ordinary situations.
If there is no trash can nearby, people often carry their garbage until they find somewhere appropriate to dispose of it—or take it home.
At food courts, people return their trays. At parks and picnic spots, they take their garbage with them. After using a shared facility, they generally leave it ready for the next person.
Both Tatsu tori ato o nigosazu and “leave it cleaner than you found it” reflect the same basic idea:
Someone will use this place after you.
The Same Habit Appears Overseas
This behavior has attracted attention outside Japan as well.
At soccer stadiums in Japan, it has long been common to see supporters cleaning up the area around their seats after a match.
What drew international attention was that Japanese supporters continued the same habit when they traveled overseas.
At FIFA World Cups, Japanese fans have repeatedly been filmed remaining in the stands after matches and collecting bottles, food containers, and other trash into bags. During the 2022 World Cup in Qatar, their post-match cleanup again became a global news story.
To international observers, it can look like an organized volunteer activity.
For many Japanese supporters, however, it may feel closer to simply doing abroad what they already do at home.
They grew up cleaning classrooms and hallways, hearing phrases such as “leave it cleaner than you found it,” and taking responsibility for the garbage they produce.
The same everyday habits can show up even in a stadium thousands of kilometers from Japan.
What Does “Don’t Cause Trouble for Others” Really Mean?
Japanese children often hear another phrase when learning manners:
“Don’t cause trouble for other people.”
In Japanese, the word meiwaku means inconvenience, trouble, or nuisance.
This does not refer only to serious problems.
If you leave your garbage on a bench, the next person may have to deal with it. Someone else will eventually have to pick it up.
If you leave a public restroom dirty, the next person has to use it that way.
If you leave your food court table covered with trays and trash, someone else has to clear away what you left behind.
Seen this way, “not causing trouble for others” can include something very simple:
Do not make a stranger clean up after you.
Instead of thinking of a public space as belonging to nobody, it can be treated as a place everyone uses—and therefore a place each person has some responsibility to use carefully.
This connects naturally with school cleaning, carrying your own trash, and the idea behind Tatsu tori ato o nigosazu.
Of course, not every Japanese person behaves this way all the time. But Japanese daily life gives people many opportunities to think about who will use a place after them.
Professional Cleaners Also Prepare the Space for the Next Person
Professional cleaning staff are, of course, essential to keeping Japan clean.
Stations, airports, shopping centers, public restrooms, and other busy places remain usable because people work every day to clean and maintain them.
What is also interesting in Japan is that some cleaning services treat their work as preparing a space to welcome the next user, rather than simply removing visible dirt.
A famous example is JR East Techno Heart TESSEI, which cleans Shinkansen trains at Tokyo Station.
During the short turnaround between arriving and departing trains, staff clean seats, tables, floors, restrooms, and other areas in roughly seven minutes. When the job is finished, staff line up on the platform, bow, and prepare to welcome the next passengers.
The impressive part is not just the speed of the cleaning. Preparing the train for the next customer is treated as part of the job.
Public restrooms provide another interesting example.
THE TOKYO TOILET is a project that redesigned 17 public toilets in Tokyo’s Shibuya area with the help of internationally known creators including Tadao Ando, Kengo Kuma, and Shigeru Ban.
The project is known for its architecture, but maintenance is just as important.
Along with daily cleaning, the facilities receive regular deep cleaning and professional inspections. Exterior walls, lighting, ventilation equipment, and other areas that users may barely notice are also maintained.
Users try not to leave unnecessary dirt behind.
Cleaning staff prepare the space so the next person can use it comfortably.
Different people are involved, but the same idea appears again:
Leave the place in good condition for whoever comes next.
Japan’s Cleanliness Is Built One Small Habit at a Time
- Take off your shoes at the entrance.
- Change into separate toilet slippers.
- Remove even your indoor slippers before stepping onto tatami.
- Put things away so the room can be used again.
- Wash before entering the bath.
- At school, clean not only your classroom, but also hallways and other shared spaces.
- If there is no trash can, carry your garbage with you.
- Remember sayings such as Tatsu tori ato o nigosazu and “leave it cleaner than you found it”—and sometimes continue the same habit even in a stadium overseas.
When you put these small actions together, a common idea begins to appear.
- Keep dirt from spreading where possible.
- Put things back when you are finished.
- Do not leave your cleanup for someone else.
- And remember that another person will use the space after you.
So when you travel through Japan and notice a clean street, station, or public restroom, look beyond the question, “Who cleans this place?”
Watch how people use the space as well.
Taking off shoes, cleaning a classroom, carrying trash home—each is a small, ordinary habit.
Together, they help explain why so much of Japan stays clean.
