If you're planning to rent an apartment in Japan, you'll quickly discover that monthly rent is only one part of the total cost.

Many first-time renters are surprised to learn about additional move-in fees such as:

• Security Deposit (Shikikin)
• Agency Fee
• Guarantor Fee
• Insurance
• Key Money (Reikin)

Among these costs, Key Money is often the most confusing for foreigners.

Unlike a deposit, key money is generally:

Non-refundable.

Once paid, you typically do not get it back when you move out.

So what exactly is key money, why does it exist, and can you avoid paying it?

Let's take a closer look.

What Is Key Money (Reikin)?

Key money, known in Japanese as:

礼金（Reikin）

is a payment made directly to the landlord as part of the move-in costs.

Historically, it was considered a gesture of gratitude toward the property owner.

Today, it remains a common feature of the Japanese rental market, although its importance has decreased significantly.

Unlike a security deposit:

• It is not held for damages.
• It is not returned when you leave.
• It becomes income for the landlord.

For many foreigners, it feels unusual because similar fees rarely exist in other countries.

Why Does Key Money Exist?

The origins of key money date back to Japan's post-war economic growth period.

During that time:

• Urban housing was limited.
• Demand greatly exceeded supply.
• Tenants competed for available apartments.

Paying extra money helped applicants secure desirable properties faster.

Over time, the practice became part of Japan's rental culture and continues today in some segments of the market.

Is Key Money Mandatory?

The simple answer is:

No.

Many people assume every apartment in Japan requires key money, but this is no longer true.

In fact, the majority of rental properties today do not require it.

According to a survey by Japan's Ministry of Land, Infrastructure, Transport and Tourism:

• Only about 41.6% of renters reported paying key money.
• Most of those who paid gave approximately one month's rent.

This means many renters can find apartments without paying any key money at all.

How Much Does Key Money Usually Cost?

The most common amount is:

However, some properties may charge:

• Half a month's rent
• One month's rent
• Two months' rent

depending on location and demand.

Government survey data shows the national average key money payment is approximately:

per rental contract.

Why Do Some Landlords Still Charge Key Money?

If key money is optional, why do some landlords continue charging it?

There are several reasons.

1. The Property Is Highly Desirable

Properties with strong demand often charge key money.

Examples include:

• Newly built apartments
• Luxury residences
• Apartments near major stations
• Properties with premium amenities

Because landlords know someone will rent the property, they have little incentive to remove extra fees.

2. Screening for Financial Stability

Some landlords believe tenants who can comfortably pay key money are more financially stable.

Their reasoning is simple:

If a renter can afford higher move-in costs, they may be less likely to miss future rent payments.

Whether this assumption is accurate or not, it remains a factor in some cases.

3. Making Rent Look Cheaper

Another strategy involves reducing monthly rent while charging key money upfront.

For example:

Option A

Monthly Rent:

No key money.

Option B

Monthly Rent:

Plus one month's key money.

At first glance, Option B looks cheaper.

However, over a standard two-year lease, the landlord may actually earn more overall.

How Can You Avoid Paying Key Money?

Fortunately, there are several practical ways to avoid this expense.

Method 1: Search Only for No-Key-Money Apartments

The easiest solution is simple:

Only search for properties labeled "No Key Money."

Today, many rental websites allow renters to filter listings based on:

• No key money
• No deposit
• No guarantor fee

This instantly removes many properties that require additional upfront costs.

Tell Your Real Estate Agent

If you work with an agent, clearly explain:

"I only want properties with no key money."

This helps narrow your options and avoids wasting time viewing unsuitable apartments.

Most agents can quickly identify qualifying properties.

Method 2: Consider Share Houses

Share houses have become increasingly popular among:

• Students
• Young professionals
• New arrivals to Japan

Many share houses charge:

• No key money
• No deposit
• No agency fee
• No guarantor fee

This dramatically lowers initial move-in costs.

Method 3: Negotiate

Many renters don't realize that some rental fees are negotiable.

While major discounts are uncommon, landlords occasionally agree to:

• Reduce key money
• Lower rent slightly
• Waive certain fees

especially during slower rental periods.

When Is Negotiation Most Effective?

Negotiation tends to work better for:

Older Properties

Landlords may be more flexible.

Long-Term Vacancies

Properties vacant for extended periods are often easier to negotiate.

Summer Months

Rental demand typically decreases after the busy spring moving season.

How Much Discount Can You Expect?

Most successful negotiations result in relatively small savings.

A realistic target is often:

rather than massive reductions.

Still, every savings helps reduce overall move-in costs.

When Negotiation Usually Doesn't Work

Certain properties rarely offer discounts:

• Newly constructed apartments
• Luxury residences
• Prime Tokyo locations
• Highly competitive listings

If demand is already strong, landlords generally have little reason to negotiate.

Should Foreigners Worry About Key Money?

Not necessarily.

While key money often receives a lot of attention online, the reality is that many apartments today do not require it.

Rather than focusing solely on key money, renters should evaluate:

• Total move-in costs
• Monthly rent
• Location
• Commute convenience
• Building quality

Sometimes a property with key money may still offer better overall value.

Understanding Total Move-In Costs

Before signing a lease, always calculate the complete initial payment.

This may include:

• First month's rent
• Deposit
• Key money
• Agency fee
• Insurance
• Guarantor company fee

In some cases, total move-in costs can equal:

depending on the property.

Final Thoughts

Key money is one of Japan's most unique rental customs.

Although it originated from historical housing shortages, today's rental market offers many alternatives.

For renters looking to reduce expenses:

1. Search for no-key-money apartments.
2. Consider share houses or short-term rentals.
3. Negotiate when possible.

By understanding how key money works and planning your budget carefully, you can significantly reduce move-in costs and find a rental property that fits both your lifestyle and financial goals.
