Value Village ／ Everyday know-how

Japanese apartment buildings are quiet, and newcomers assume the walls are thick. They are not. The quiet comes from a shared set of habits about what you do after 21:00, how you close a door, and what you say when you move in.
| Time | What is avoided in flats |
|---|---|
| Before 8:00 and after 21:00–22:00 | Washing machine, vacuum cleaner, hair dryer near a shared wall, musical instruments, loud TV |
| After 22:00–23:00 | Bathing in older buildings with noisy plumbing (varies), moving furniture, phone calls on the balcony |
| Any time | Walking in shoes indoors, slamming doors, running children (rugs and play mats are used), balcony parties |
[Verify] Tokyo ordinance limits with the Tokyo Metropolitan Government's environmental noise standards; complaint statistics with the Ministry of the Environment.
Light construction is normal; you will hear your neighbour's alarm. The quiet is because everyone acts as if the walls were paper.
Daytime is more tolerant, but shift workers and infants sleep in the day. A vacuum at 10:00 is fine; drums are not.
They do not chat, but the move-in greeting is expected, and it is the moment that determines whether a later noise is forgiven or reported.
Direct confrontation is avoided. Tell the management company or landlord, who deliver an anonymous notice to the whole floor. Doing this yourself, politely, is acceptable only for a one-off.
It is the most disputed category. Households with children use thick play mats, rugs and slippers, and greet the downstairs neighbour specifically.
