What is Key Money in Japan? (礼金 / Reikin) — Complete Guide
Key money (礼金) is a non-refundable upfront payment unique to Japan's rental market. Learn what it is, why it exists, how much it costs, and how to avoid paying it.
If you've been browsing apartment listings in Japan, you've probably noticed the term 礼金 (reikin) — often translated as "key money." It's one of the more confusing aspects of renting in Japan, particularly because it has no direct equivalent in most Western countries.
Here's everything you need to know.
Key Takeaways
- Key money is a non-refundable gift paid to the landlord at lease signing — you will not get it back
- Typical amount: 0–2 months' rent
- It is declining — many modern apartments now offer 0 key money
- It is not required by law — it's negotiable, especially for long-vacant apartments
- Foreigners and first-time renters in Japan are often surprised by this cost: budget for it upfront
What is Key Money?
Key money (礼金, literally "gratitude money") is a one-time payment made by the tenant to the landlord when signing a lease. It is separate from the security deposit and is completely non-refundable.
Think of it as a customary fee for the privilege of renting the property. It has no legal basis — it's a cultural practice rooted in post-war Japan.
Why Does Key Money Exist?
The origin of key money dates back to post-WWII Japan, when housing was severely scarce. Desperate tenants would offer "gifts" to landlords to secure apartments. Over decades, this informal practice became institutionalized.
Today, the justification is weakening. In many parts of Japan — especially suburban areas, newer buildings, and share houses — key money has been abolished. However, it remains common in:
- Central Tokyo (especially older buildings)
- Kyoto (historically strong custom)
- Some parts of Osaka
How Much is Key Money?
| Situation | Typical Key Money |
|---|---|
| New or renovated apartment, suburban | ¥0 (increasingly common) |
| Standard apartment, mid-city | 1 month's rent |
| Older apartment, central Tokyo or Kyoto | 1–2 months' rent |
| High-demand property, landlord's market | Up to 2 months' rent |
For a ¥100,000/month apartment in central Tokyo with 2 months' key money, that's ¥200,000 gone on day one.
Key Money vs Security Deposit: What's the Difference?
| Key Money (礼金) | Security Deposit (敷金) | |
|---|---|---|
| Purpose | "Gift" to landlord | Held against damage/unpaid rent |
| Refundable? | No | Partially (after deductions) |
| Typical amount | 0–2 months' rent | 1–2 months' rent |
| Negotiable? | Sometimes | Rarely |
Security deposit money comes back (mostly). Key money never does.
Is Key Money Negotiable?
Yes — especially in these situations:
- The apartment has been vacant for 2+ months
- You're signing during off-peak season (summer and winter, outside March–April)
- The building is older or in a less desirable area
- You're offering a longer lease (2+ years)
A polite request through your real estate agent — not directly to the landlord — is the standard approach. Agents often handle this negotiation on your behalf.
How to Find 0 Key Money Apartments
Most major rental platforms allow you to filter by 礼金なし (no key money):
- SUUMO (suumo.jp) — filter by 礼金0
- at home (athome.co.jp)
- GaijinPot Apartments — English-language, foreigner-friendly listings
- Sakura House — specifically targets international residents
Note that 0 key money listings sometimes compensate with higher security deposits or slightly higher monthly rents. Always calculate the total first-year cost before comparing.
Summary
| With Key Money (2 months) | Without Key Money | |
|---|---|---|
| Upfront extra cost | 2 × monthly rent | ¥0 |
| Total advantage over 2-year lease | Break-even | Save 2 months' rent |
Key money is a uniquely Japanese rental custom that's slowly fading. If you're flexible on location or building age, there's a good chance you can find a quality apartment with zero key money — especially outside central Tokyo and Kyoto.
