Value Village ／ Everyday know-how
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Almost every visitor knows shoes come off at the door. Fewer notice that the habit shapes how the whole home is built, sized and cleaned.
The entrance is a boundary. Everything beyond it is a surface people sit, sleep and put food on.
Japan's 2023 Housing and Land Survey puts the average floor area of a dwelling at 90.86 m², with 4.26 rooms and 14.65 tatami-mat equivalents of living space per person. In a home that size, the floor is not just walked on. It is where a futon goes at night and where a low table sits at mealtimes.
When the floor is furniture, the floor has to stay clean. The shoe rule follows from that.

Removing shoes keeps street dirt at the door. It is a hygiene system before it is a courtesy.
The *genkan* is usually a step lower than the rest of the home. That step is the line: shoes below it, socks above it. The height difference is doing the work, not a sign on the wall. Even modern flats with no tatami keep some version of it.
Picture scrolls from the Heian period (794–1185) already show footwear being removed before entering residences. The habit predates most of the architecture around it.
Many homes keep separate slippers for the toilet. Wearing them back into the living space defeats the purpose. If a different pair is waiting at a door, it is waiting there for a reason.
Some clinics, schools, traditional restaurants, temples and fitting rooms follow the same rule. Watch what the people ahead of you do at the entrance.
