How to Deal with Neighbors in Japan

Learn the customs of apartment life in Japan and the practical points that help you avoid trouble with neighbors.

In Japanese apartment life, relationships with neighbors matter more than many newcomers expect. You may not meet them often, but noise and shared-space behavior can easily become sources of conflict.

Moving-in greetings

Japan has a custom of briefly greeting nearby neighbors when you move in. It is not mandatory, but it creates a better first impression.

Who people often greet:

• The apartments on both sides
• The units above and below, since sound travels easily
• Sometimes the ground-floor unit if the mailboxes or entrance are shared closely

What people sometimes bring:

• A small greeting gift such as a towel, snacks, or detergent, usually around ¥500 to ¥1,000
• Even without a gift, a simple knock on the door and a short greeting is enough

A typical line is:

“I’ve just moved in. My name is ____. Nice to meet you.”

Noise rules

Walls in Japanese apartments are often thin, so sound carries easily.

Things to be especially careful about:

• 10:00 p.m. to 8:00 a.m.: Keep everyday noise to a minimum. Lower the TV and music volume or use headphones.
• Footsteps: They can carry surprisingly far. Soft slippers or walking barefoot can reduce noise.
• Washing machines: Avoid running them late at night or very early in the morning.
• Loud conversations when guests visit: Close windows and doors.

Rules for shared spaces

• Do not leave personal belongings in hallways or stairwells. This can also violate fire-safety rules.
• Use the designated bicycle parking area.
• Do not make a mess around the garbage collection area.
• Keep phone calls quiet in the entrance or elevator.

If there is a noise problem

Going directly to a neighbor to complain is often risky because it can make the relationship worse. In Japan, it is more common to contact the building management company and ask them to handle it.
