How renting in Japan
actually works.
Japan's rental market has customs and costs that catch nearly every first-time expat off guard. Here's an honest, detailed walkthrough — so you know exactly what to expect before you sign anything.
The real cost of
moving in.
Before you move in, expect to pay several months' worth of rent in upfront fees. This surprises almost every expat. Here's what each item is:
| Item | Typical Amount | What it is |
|---|---|---|
| Key Money (礼金) | 0–2 months' rent | A non-refundable "gift" to the landlord. A holdover from post-war Japan. Not universal, but still common in premium properties. |
| Security Deposit (敷金) | 1–2 months' rent | Refundable (in part), used to cover damages or cleaning at move-out. Deductions are often disputed. |
| Agency Fee (仲介手数料) | 1 month's rent + tax | Standard brokerage commission. By law, this can be split between landlord and tenant, but in practice tenants usually pay the full amount. |
| Guarantor Company (保証会社) | 0.5–1 month's rent | Required for most leases. Acts as a co-signer. Foreign nationals almost always need this. |
| Fire Insurance (火災保険) | ¥15,000–¥30,000/2yr | Mandatory. Covers fire, water damage, and theft. Usually arranged through the agent. |
| First Month's Rent | 1 month (often prorated) | Paid at signing. |
| Typical Total | 4–6 months' rent | For a ¥300,000/month apartment, budget ¥1.2M–¥1.8M to move in. |
Key money is negotiable — but only if you know to ask, and only if your agent is willing to advocate for you. Most agents won't push back on this because it doesn't benefit them to do so. I do.
From search to
move-in day.
Things nobody
tells you.
Foreign nationals face extra hurdles
Many landlords — particularly older owners of high-end properties — are reluctant to rent to non-Japanese tenants. This is technically illegal but widely practiced. I know which buildings are genuinely international-friendly, and which aren't worth applying to.
Move-out costs can be significant
Japan's rental standard (原状回復) requires tenants to return the property to its original condition. This is interpreted aggressively by some landlords. I help clients document the move-in condition carefully to protect against unfair deductions.
Lease renewals aren't automatic
Most leases are 2-year fixed-term contracts with a renewal fee (更新料) of 1 month's rent. This is often omitted from initial quotes. Always ask about renewal terms before signing.
Furnished units are rare and expensive
The Japanese rental market is almost entirely unfurnished. Serviced apartments exist but command a significant premium. I can help source quality furniture quickly for clients who need to be operational immediately.
"The biggest mistake I see expat executives make is relying solely on their company's HR department for housing. HR's job is to keep costs down — not to find you the best apartment. That's what I do."
