Hidden Apartment Costs in Japan｜Why Your First Rent Bill Can Be 4 Times Higher Than Expected

You find an apartment in Japan for 80,000 yen per month.

It looks perfect. The station is close. The room is clean. The rent fits your budget.

Then the real estate agent sends the first estimate.

280,000 yen. 350,000 yen. Sometimes even more.

For many foreigners, this is the moment Japan’s rental system suddenly feels confusing, expensive, and unfair.

The monthly rent is only one part of the real cost. If you only compare rent prices, you may choose an apartment that looks cheap but becomes expensive at move-in.

This guide explains the hidden apartment costs in Japan, what each fee means, which fees may be negotiable, and how foreigners can avoid expensive surprises before signing a lease.

Why the first apartment bill in Japan feels so high

In many countries, moving into an apartment usually means paying the first month’s rent and a deposit.

Japan can be different.

The first payment often includes several separate fees. Some are refundable. Some are not. Some are required by the landlord. Some are charged by the real estate agency. Some are connected to the guarantor company or insurance.

Cost	Common Japanese term	Usually refundable?
Security deposit	Shikikin	Sometimes partly refundable
Key money	Reikin	No
Agency fee	Chukai tesuryo	No
Guarantor company fee	Hosho gaisha fee	No
Fire insurance	Kasai hoken	No
Lock change fee	Kagi kokan dai	No
Cleaning fee	Cleaning dai	Usually no
First month rent	Yachin	No
Prorated rent	Hibari yachin	No

A simple example of move-in costs

Imagine you apply for an apartment with monthly rent of 80,000 yen.

The listing looks affordable. But the first estimate may look like this:

Item	Example amount
First month’s rent	80,000 yen
Security deposit	80,000 yen
Key money	80,000 yen
Agency fee	88,000 yen
Guarantor company fee	40,000 yen
Fire insurance	20,000 yen
Lock change fee	16,500 yen
Cleaning fee	44,000 yen
Total	448,500 yen

This is only an example. Actual costs depend on the property, area, agency, landlord, contract type, and campaign.

But it shows why foreigners are shocked. The apartment was advertised as 80,000 yen per month, but the first payment can be several times that amount.

Security deposit: what it really means

The security deposit is called shikikin.

This money is usually held by the landlord. It may be used for unpaid rent, cleaning, or repair costs when you move out.

Many foreigners think the deposit will always come back in full. That is not always true.

Take photos when you move in. Walls, floors, doors, sinks, windows, air conditioner, bathroom, balcony, and existing scratches should be recorded.

This can help avoid trouble when you move out.

Key money: the fee foreigners hate most

Key money is called reikin.

It is usually paid to the landlord and is normally not refunded.

For many foreigners, key money is the most confusing fee in Japan. It does not work like a deposit. It is not rent. It is not usually returned when you leave.

A room with no key money is not always cheaper overall. Sometimes the monthly rent is higher, or other fees are added.

Always compare the total cost, not just one fee.

Agency fee: paying the real estate agent

The agency fee is paid to the real estate company that helps you rent the apartment.

It is often around one month’s rent plus tax, but the exact amount can vary.

This fee is not refundable. It is the cost of the agency service.

Before applying, ask if the agency fee is:

• One month’s rent
• Half month’s rent
• Free under a campaign
• Charged with tax

Do not assume the agency fee is included in the rent estimate. Ask clearly.

Guarantor company fee: a major cost for foreigners

Many foreigners cannot provide a Japanese individual guarantor. Because of this, many apartments require a guarantor company.

The guarantor company checks your application and may cover certain risks for the landlord if rent is unpaid.

This helps many foreigners rent apartments, but it adds another cost.

Guarantor cost	What to check
Initial guarantor fee	How much is charged at contract signing?
Annual renewal fee	Is there a yearly fee?
Monthly fee	Is a small monthly fee added?
Screening	What documents are needed?

Even if you have enough money, you still need to pass screening.

The guarantor company may check your income, visa status, Japanese phone number, emergency contact, and ability to communicate.

Fire insurance: small but usually required

Fire insurance is commonly required when renting an apartment in Japan.

It may cover fire, water damage, liability, or other housing-related risks depending on the policy.

Foreigners often ignore this fee because it looks small compared with key money or deposit, but it is still part of the real move-in cost.

Before signing, check:

• How much it costs
• How long it covers
• Whether renewal is required
• What it covers

Lock change fee: why you may pay for new keys

Some apartments charge a lock change fee before move-in.

The idea is to replace or reset the lock after the previous tenant leaves.

For safety, this can make sense. But for foreigners, it may feel like another unexpected charge.

Ask whether the lock change is required or optional. Some contracts make it mandatory.

Cleaning fee: sometimes charged before you even live there

Cleaning fees can be confusing.

Some apartments charge cleaning fees when you move out. Others charge them at the beginning. Some deduct cleaning costs from your deposit.

This matters because a room may look cheap at first but include a fixed cleaning fee later.

Also ask whether cleaning is charged even if you leave the room clean.

24-hour support fee and other small charges

Some apartments include extra service fees.

These may include:

• 24-hour emergency support
• Key trouble support
• Water trouble support
• Pest control fee
• Disinfection fee
• Administrative fee
• Document fee

Some fees may be useful. Some may feel unnecessary.

Ask the agent which fees are required and which are optional.

Prorated rent: paying for part of the month

If you move in during the middle of the month, you may pay prorated rent.

For example, if your rent is 90,000 yen and you move in halfway through the month, you may pay rent for the remaining days plus the next full month.

This is normal, but it can make the first bill higher than expected.

Renewal fee: the cost that appears later

Some rental contracts in Japan include a renewal fee.

This fee may appear when the lease renews, often after two years.

Foreigners often forget to check this because they focus only on move-in costs.

A cheaper apartment can become more expensive later if renewal fees are high.

Move-out costs: the hidden final bill

The final surprise may come when you leave.

Move-out costs can include cleaning, repairs, restoration, unpaid fees, or early cancellation penalties.

Before signing, ask exactly what happens when you move out.

Move-out cost	What it means
Cleaning fee	Charged for room cleaning after leaving
Restoration cost	Cost to repair damage beyond normal use
Early cancellation penalty	Fee if you leave before a minimum period
Deposit deduction	Amount taken from your security deposit
Disposal fee	Cost for items left behind

Take photos both when you move in and when you move out.

This simple habit can protect you from unnecessary disputes.

How foreigners can compare apartments correctly

Do not compare apartments by monthly rent only.

Compare the total cost for the period you plan to stay.

For example, if you plan to stay one year, calculate:

• Initial costs
• Monthly rent
• Management fee
• Guarantor renewal fee
• Insurance
• Internet cost
• Move-out cleaning fee
• Cancellation penalty

This gives you a more honest picture.

How to reduce apartment costs in Japan

You may not be able to remove every fee, but you can reduce your risk.

Temporary housing can be useful when you first arrive in Japan.

It gives you time to get a Japanese phone number, register your address, open a bank account, learn the area, and compare apartments calmly.

Questions to ask the real estate agent

Before you apply, ask clear questions.

If the agent cannot explain the costs clearly, be careful.

Red flags in apartment cost estimates

Some estimates are normal but still expensive. Others are unclear and should be questioned.

Do not sign because you feel embarrassed to ask questions.

Housing is expensive. Questions are normal.

FAQ

Why are apartment move-in costs so high in Japan?

Move-in costs can be high because the first bill may include rent, deposit, key money, agency fee, guarantor company fee, insurance, cleaning fee, lock change fee, and other charges.

Is key money refundable?

Usually, key money is not refundable. It is different from a security deposit.

Can I find apartments with no key money?

Yes. Many apartments advertise no key money, but you should still check the full estimate because other fees may apply.

Do foreigners need a guarantor company?

Many foreign renters use guarantor companies because they do not have a Japanese individual guarantor. Some properties require one.

What is the biggest mistake foreigners make?

The biggest mistake is comparing apartments only by monthly rent. You should compare total move-in cost, monthly cost, renewal cost, and move-out cost.

Can I negotiate apartment fees in Japan?

Sometimes. It depends on the property, landlord, season, and market. Key money, agency fee, or move-in date may sometimes be discussed, but not always.

Should I use temporary housing first?

For many newcomers, yes. Temporary housing can give you time to prepare documents, get a phone number, open a bank account, and search without pressure.

Final thoughts

Apartment costs in Japan can feel shocking because the monthly rent does not show the whole story.

A room that looks affordable online may become expensive when key money, deposit, agency fee, guarantor company fee, insurance, cleaning fee, lock change fee, and prorated rent are added.

For foreigners, the safest strategy is to ask for the full estimate before applying and compare apartments by total cost, not rent alone.

Before signing, understand what is refundable, what is not refundable, what may appear later, and what you may pay when moving out.

If you are new to Japan, do not rush into a contract because you need a room quickly. Temporary housing may save you from panic renting and expensive mistakes.

The best apartment is not always the one with the lowest rent.

It is the one where you understand the full cost before you sign.
