The rent figure on a listing (yachin) is the number that gets your attention — but it's the smallest part of what you pay to actually move in. This is exactly the kind of place where "I'll just budget one month" quietly leaves you short by a few hundred thousand yen. Mio doesn't do surprises — here's the whole bill, line by line. All figures are illustrative ranges; the real numbers vary widely by property, area, and landlord.
Japanese rental contracts stack several one-off charges on top of the first month. Add them up and the total shokishoku hiyō (initial cost) commonly lands around 4–6 months' rent. On a ¥80,000/month apartment, that's roughly ¥320,000–480,000 before you've unpacked a single box — illustrative, and some contracts run higher or lower.
| Line item | Typical range (months of rent) |
|---|---|
| Shikikin — deposit (敷金) | 1–2 months (refundable*) |
| Reikin — key money (礼金) | 0–2 months (usually non-refundable) |
| Agency fee — chūkai tesūryō (仲介手数料) | ~1 month + tax |
| Guarantor company fee — hoshō gaisha (保証会社) | ~0.5–1 month upfront (+ annual renewal) |
| First month rent + maintenance (kanrihi) | ~1 month |
| Fire insurance (kasai hoken) | ~¥15,000–25,000 / 2 yrs (flat, not monthly) |
| Key exchange (kagi kōkan) | ~¥10,000–25,000 (flat) |
| "Cleaning fee" (clean-up / sometimes upfront) | ~¥20,000–50,000 (varies; often deducted later) |
*Shikikin is refundable in principle, but the landlord deducts restoration/cleaning costs when you leave, so you rarely get all of it back. Reikin is a gift to the landlord and does not come back.
Shikikin (deposit) is security held against damage and unpaid rent. In principle it's returned when you move out, minus fair restoration costs (genjō kaifuku). Reikin (key money) is a one-off, non-refundable payment to the landlord — historically a "thank you" for renting to you. It buys you nothing tangible and you never see it again, which is why zero-reikin listings are worth hunting for.
Traditionally a Japanese renter needed a personal guarantor (rentai hoshōnin) — usually a family member with Japanese income — to co-sign the lease. Most foreign residents don't have one. That's precisely why guarantor companies (hoshō gaisha) exist: for a fee (~0.5–1 month upfront, plus a smaller annual renewal), the company acts as your guarantor. For many foreigners this isn't optional — the landlord requires it. It's an added cost, but it's also the mechanism that makes renting possible without a Japanese co-signer.
"Zero-zero" (ゼロゼロ) properties advertise no key money and no deposit. That removes the two biggest one-off lumps, so move-in can drop toward 2–3 months' rent. Read the fine print: some recover the cost through higher monthly rent, a mandatory cleaning fee, or a short-stay penalty clause.
UR public housing (UR賃貸) is run by a public agency and is genuinely built to be foreigner-friendly on cost: no key money, no agency fee, and no guarantor required. You typically pay a larger deposit and must meet an income standard, but you skip reikin, the agency fee, and the guarantor company entirely — often a big saving over a private lease.
Budget 4–6 months' rent for a normal private lease, and don't let the monthly figure fool you. If cash upfront is tight, hunt zero-reikin or zero-zero listings, or check UR — those are the levers that actually move the number. Then furnish smart: buy secondhand vs new furniture → to keep the first-month total down.
