Finding a home in Japan can feel like an exciting adventure, however it also comes with a distinct set of rules and expectations that can trip up even the savviest expatriates.

Whether you want a snug studio in Tokyo or a roomy family home in the suburbs, avoiding the most common pitfalls will save you time, money, and a lot of 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.

Many foreigners sign a lease after a quick glance, only to uncover hidden clauses later.

Make sure to read the lease carefully, and if any part is unclear, ask the landlord or a Japanese-speaking friend to explain.

Pay close attention to:

The precise move‑in and move‑out dates, along with any required notice periods.

Whether the lease is for a particular address or the whole building.

Any limits on subletting or pet ownership.

If you’re not fluent in Japanese, consider hiring a translator or a bilingual real‑estate agent to help 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 smaller amount (often one month’s rent) that covers minor repairs and is usually 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

The split of utility responsibilities between landlord and tenant in Japan is often confusing.

Some leases include "水道光熱費" (water and electricity) in the monthly rent, while others require you to set up separate accounts with utility companies.

Not knowing who pays for what can cause surprise bills. Clarify:

Who is responsible for electricity, 名古屋市東区 ペット可賃貸 相談 gas, water, and internet.

Whether the landlord provides a meter reading service or you need to sign up for a separate account.

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

If unclear, request a written summary of utility responsibilities from the landlord.

Overlooking the Registration of Residence (住民票)

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

Skipping registration can result in fines and issues with official mail, bank accounts, or health insurance.

Foreigners often overlook this because the lease doesn’t mention 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 mandate a "maintenance fee" for building upkeep.

Others may restrict painting or installing new fixtures.

Prior to signing, inquire about:

What the maintenance fee covers.

If cosmetic changes are allowed.

How frequently the building is inspected or renovated.

Assuming All Apartments Are "Pet‑Friendly"

Japan’s love for cats and small dogs is well‑known, but the reality of pet ownership in rented apartments is mixed.

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

If bringing a pet, verify:

The lease’s pet policy details.

If a pet deposit or fee is required.

Any limits on pet size or number.

Neglecting the "No Smoking" Rule

Japanese apartments enforce strict no‑smoking policies.

Even in designated smoking rooms, smoke may infiltrate adjacent units via ventilation.

Some leases outright forbid smoking inside.

Violating this policy can lead to hefty fines or even eviction.

If you smoke, ask about designated smoking areas and confirm that you’re allowed to do so within the building.

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 assess the apartment against the move‑in inspection.

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

To avoid surprises:

Keep a comprehensive move‑in inspection report and photos.

Fix any visible damage before leaving.

Ask for a final inspection before departure.

Skipping the "Contract Renewal" Process

Leases usually span one year and renew automatically if no notice is provided.

Some tenants forget to negotiate a new lease or don’t realize the rent may increase at renewal.

To stay prepared:

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

Negotiate a fixed‑rate renewal for long‑term stays.

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.

Consider visiting a local real‑estate office, especially in popular neighborhoods.

An agent can aid with language, better terms, and lease legitimacy.

Not Understanding the "Landlord’s Right of Entry

Landlords can enter for inspections or repairs but must give notice.

Tenants often feel blindsided by unexpected entries.

Confirm the notice period (typically 24–48 hours) and entry reasons.

Knowing this can help 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.

You may forget you need a futon, a table, or a fridge.

Plan for these items and inquire about essential appliances.

Some landlords sell a "furniture and appliance package" for extra cost.

Disregarding the "Noise Regulations

Japan is known for its quiet culture, and noise complaints can lead to eviction.

Remember:

Quiet hours (often 10 pm to 7 am).

The use of 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

Some landlords perform a "home inspection" before you move in to ensure the apartment’s condition.

Skipping it or not asking for a report may cost you for damage you caused.

Always obtain a written inspection report and retain it.

Not Planning for "Moving Day Logistics

Moving in Japan can be tricky.

Landlords may impose move‑in times, and narrow staircases can hinder large trucks.

Plan ahead:

Book a moving company that specializes in Japanese apartments.

Inquire about moving‑time restrictions.

Have a backup plan in case the moving company is delayed.

Read the lease completely and seek clarification on confusing clauses.

Confirm the deposit, key money, and maintenance fee specifics.

Confirm utility responsibilities and set up accounts if needed.

Register your residence within two weeks after moving in.

Be aware of pet, smoking, and noise policies.

Keep detailed inspection reports and photos.
