Why do people take their shoes off at the entrance of a home?
At the genkan (a sunken entryway just inside the door), you remove your outdoor shoes, step up onto a raised floor, and switch to slippers or socks. Homes, many clinics, some restaurants, temples, and traditional inns all expect this.
The genkan marks a physical and symbolic boundary between the dirty outside and the clean inside, so shoes that touched the street stay outside it.
Why — five layers
There is a strong awareness of separating inside from outside and of not bringing dirt from outdoors into living spaces.
Traditionally, people sat and ate directly on tatami or flooring and slept on futons laid over tatami, so keeping the floor clean was important.
Homes are designed around the custom of removing shoes and commonly include a lower genkan floor and shoe cabinet. Schools and workplaces may also provide places to change footwear, embedding the custom in everyday life.
International view
Removing shoes indoors is widespread across East, Southeast, and South Asia and much of the Middle East, and common in Nordic countries; the built-in sunken genkan and the crisp step-up are the more distinctly Japanese parts.
But not always
The custom of removing shoes does not apply everywhere. Restaurants, offices, shops, hotels, and other places may allow people to enter without taking them off.
What to do
If you are unsure whether to remove your shoes, look for a shoe cabinet or slippers and see whether other people are taking theirs off. Place removed shoes neatly with the toes pointing toward the exit.
