Japanese apartment life has an unwritten rulebook — and some very written ones in your lease. Breaking these rules can result in warnings from your landlord, complaints from neighbors, or in serious cases, lease termination.

Noise Rules

Noise is the number one cause of neighbor complaints in Japanese apartments.

Quiet Hours

  • Most buildings have quiet hours: 10pm–8am (or similar)
  • Some specify stricter rules: after 9pm in older buildings

Common Noise Violations

  • Running and stomping — sound travels dramatically through thin Japanese floors
  • Vacuuming before 9am or after 9pm
  • Playing music without headphones
  • Loud phone calls (heard through walls)
  • Washing machine after 9–10pm — many lease rules specifically mention this
  • TV/game audio at high volume in evenings

Floors

Ground floor is ideal if you have children or are naturally loud. If you’re on upper floors, buy a 防音マット (soundproof mat) — essential for protecting your deposit and your relationship with downstairs neighbors.

Garbage Rules

Japan’s garbage system is strict and varies by municipality. Your building will specify:

  • Separation: Burnable (燃えるゴミ), recyclables (資源ゴミ), non-burnable (燃えないゴミ), etc.
  • Designated days: Each type of garbage has specific pickup days
  • Designated time: Put garbage out on the morning of pickup day — not the night before
  • Designated location: Use the building’s garbage station (ゴミ置き場)

Breaking garbage rules is the most common foreign-resident complaint from building managers. Read your building’s rules on your first day.

Smoking

Most Japanese apartments now have no-smoking rules indoors.

  • Check your lease — many explicitly prohibit indoor smoking
  • Smoking on your balcony may also be prohibited (smoke travels to neighbors)
  • Cigarette smell that cannot be removed from walls/tatami will be deducted from your deposit

Visitors and Guests

  • Short-term guests are generally fine
  • Having someone effectively live with you without notifying the landlord can violate your lease
  • Airbnb-type subletting: explicitly prohibited in almost all Japanese residential leases

Pets

Even if you think pets are fine, check your lease:

  • Most Japanese apartments are no-pet (ペット不可) — dogs, cats, large animals
  • Some allow small pets (小動物) — hamsters, birds, fish
  • Even small pets should be disclosed — hidden pets that cause damage lose you your deposit plus extra

Modifications to the Apartment

Do not:

  • Drive nails into walls (use removable hooks — 3M Command strips work well)
  • Paint or wallpaper
  • Install shelving that requires drilling
  • Change door locks without landlord permission

When you leave, the apartment should be returned to its original condition. Damage beyond normal wear costs are taken from your deposit.

Bicycles and Parking

  • Register your bicycle at the local police box (交番) after purchase — required
  • Use your building’s designated bicycle parking area only
  • Illegally parked bicycles are removed and impounded
  • Car parking: use only your assigned space; do not park in other spots

Common Area Rules

  • Don’t store items in hallways, stairwells, or outside your door (fire code)
  • Elevators: stand aside; hold door for others
  • Entrance hall (エントランス): no loitering, keep doors closed

Communicating with Your Landlord

Build a good relationship early:

  • Give notice immediately if something breaks (water leak, broken equipment)
  • Notify before any renovation or significant change
  • If you’ll be away for an extended period, inform the management company

In Japan, silent problems become big problems. Proactive communication is valued.

Moving Out

  • Give notice (通知) as specified in your lease — usually 1–2 months in advance
  • Schedule an exit inspection (退去立ち合い) with the landlord or management company
  • Remove all belongings
  • Return all keys (front door, mailbox, bicycle parking, etc.)
  • Deposit return: Should arrive within 1 month. Deductions must be itemized in writing.
