Moving into a Japanese property can be an exciting adventure, yet there are a distinct set of rules and expectations that can trip up even the most experienced expatriates.

Whether you’re after a compact studio in Tokyo or a large family house in the suburbs, steering clear of the most common pitfalls will save you time, money, and headaches.

These are the primary mistakes to look out for and how to sidestep them.

Skipping a Comprehensive Lease Review

A lease in Japan is more than a simple contract; it’s a legal document that specifies every detail of your tenancy.

Numerous foreigners sign a lease after a quick glance, only to discover hidden clauses later.

Always read the lease carefully, and if any part is unclear, consult the landlord or a Japanese-speaking friend for clarification.

Pay close attention to:

The exact move‑in and move‑out dates, including any required notice periods.

Whether the lease covers a specific address or the entire building.

Any rules about subletting or pets.

If you’re not fluent in Japanese, think about hiring a translator or a bilingual real‑estate agent to interpret the terms.

Underestimating the Deposit and Key Money (Fukikin)

Rental agreements in Japan usually demand three primary financial components:

Deposit (Shikikin) – a refundable sum that can be up to three months’ rent. It’s meant to cover any damage or unpaid utilities, so keep records of the condition of the apartment when you move in.

Key Money (Fukikin) – a non‑refundable payment, usually one to two months’ rent, that acts as a gift to the landlord. Not all landlords demand fukikin, but many do, especially in competitive markets.

Security Deposit (Aigyo) – a modest amount (commonly one month’s rent) for minor repairs, typically refundable.

Often people assume the deposit is fully refundable, yet a part may be kept for wear and tear. Keep receipts, photos, and a move‑in inspection report. If unsure, compare with similar apartments locally.

Ignoring the Utility Responsibility Clause

Utilities in Japan are often split between the landlord and tenant in ways that can be confusing.

Some leases include "水道光熱費" (water and electricity) in the monthly rent, 名古屋市東区 マンション売却 相談 while others require you to set up separate accounts with utility companies.

Misunderstanding who pays for what can lead to unexpected bills. Clarify:

Who handles electricity, gas, water, and internet payments.

Whether the landlord offers meter readings or you must set up a separate account.

How payment is made (direct debit, bank transfer, or the "nishiki" system).

If you’re unsure, ask the landlord to provide a written breakdown of utility responsibilities.

Overlooking the Registration of Residence (住民票)

After moving in, you must register your residence at the ward office within 14 days.

Not registering can incur fines and cause problems with official mail, bank accounts, or health insurance.

This step is often forgotten by foreigners as the lease omits it.

Plan a trip to the ward office shortly after moving in, bringing your passport, residence card, and lease.

Not Checking the Building’s Maintenance Policies

Older buildings in Japan commonly have rigid rules on maintenance, renovations, and wall colors.

Some landlords require you to pay a "maintenance fee" for the building’s upkeep.

Others may limit painting or installing new fixtures.

Before signing, ask:

What the maintenance fee includes.

If cosmetic changes are allowed.

The frequency of building inspections or renovations.

Assuming All Apartments Are "Pet‑Friendly"

Japan’s fondness for cats and small dogs is clear, but pet rules in rentals differ.

Many landlords prohibit pets entirely, while others allow them only in certain areas or with an additional pet deposit.

If you plan to bring a pet, confirm:

The exact pet policy in the lease.

Whether a pet deposit or monthly fee is required.

Restrictions on pet size or quantity.

Neglecting the "No Smoking" Rule

Smoking in Japanese apartments is strictly prohibited.

Even in designated smoking rooms, smoke can seep into neighboring units through ventilation systems.

Some leases outright forbid smoking inside.

Breaking it can result in fines or eviction.

If you smoke, confirm designated smoking areas and ensure you’re allowed to smoke there.

Misunderstanding the "Move‑Out" Inspection

At the end of your lease, you’ll undergo a move‑out inspection ("退去検査").

The landlord will compare the current condition to the move‑in report.

Minor wear is acceptable; major damage can reduce your deposit.

To avoid surprises:

Maintain a detailed move‑in inspection report with photos.

Fix any visible damage before leaving.

Request a final inspection before you leave.

Skipping the "Contract Renewal" Process

Japanese leases are often for one year, with automatic renewal if no notice is given.

Tenants often neglect renewal talks or the chance of rent increases.

To avoid being caught off guard:

Ask the landlord about renewal terms and any potential rent increase.

Negotiate a fixed‑rate renewal if staying long term.

Keep a copy of the renewal contract.

Relying Solely on Online Listings

Online portals are handy, but many genuine rentals appear in local real‑estate offices or via word‑of‑mouth.

Relying only on websites can lead to inflated prices or scams.

Check local real‑estate offices, especially in hot neighborhoods.

A trusted agent can help you navigate language barriers, negotiate better terms, and ensure that the lease is legitimate.

Not Understanding the "Landlord’s Right of Entry"

Landlords may enter for inspections or repairs, yet must provide notice.

Tenants often feel blindsided by unexpected entries.

Ask about the notice period (normally 24–48 hours) and entry justifications.

Awareness helps you prepare and avoid feeling violated.

Underestimating the Cost of "Furniture and Appliances"

New builds might have basic furniture and appliances, but older units are usually unfurnished.

It’s easy to forget that you’ll need to purchase a futon, a small table, or a refrigerator.

Plan for these items and inquire about essential appliances.

Some landlords offer a "furniture and appliance package" for an additional fee.

Disregarding the "Noise Regulations

Noise complaints in Japan can trigger eviction.

Remember:

Quiet hours (commonly 10 pm–7 am).

Using loud appliances.

The habit of keeping the house tidy to avoid attracting pests.

In shared buildings, honor neighbors’ quiet hours and reduce noise.

Missing the "Home Inspection" for New Tenants

Landlords may conduct a "home inspection" before moving in.

Skipping it or not requesting a report can mean paying for your own damage.

Always ask for a written inspection report and keep it.

Not Planning for "Moving Day Logistics

Moving in Japan often proves complex.

Landlords may set a move‑in time, and narrow staircases can block large trucks.

Plan ahead:

Hire a moving firm that specializes in Japanese apartments.

Inquire about moving‑time restrictions.

Keep a backup plan if the moving company is late.
