Every Cost, Explained
Moving into an apartment in Japan involves far more than just the first month's rent. The Japanese system has accumulated a unique set of fees over decades, some of which are legally required, others practically required, and a few that are optional but pushed aggressively by agencies. Here's every line item, explained honestly.
| Cost | Japanese Term | Typical Amount | Refundable? | Notes |
|---|---|---|---|---|
| Deposit | 敷金 (Shikikin) | 1–2 months' rent | Partially | Returned minus cleaning & repair costs. Negotiate itemized deductions when leaving. |
| Key Money | 礼金 (Reikin) | 0–2 months' rent | Never | A gift to the landlord. Historically mandatory, now negotiable or zero in many cases. |
| Agency Fee | 仲介手数料 | 1 month + 10% tax | Never | Legally capped at 1 month's rent. Some agencies charge less — always check. |
| Guarantor Company Fee | 保証料 | 0.5–1 month upfront + ¥10K–20K/year | Never | Increasingly mandatory. Fee varies by company and visa type. |
| Fire Insurance | 火災保険 | ¥15,000–¥30,000 / 2 years | Never | Mandatory but you can choose your own insurer. Don't accept the agency's overpriced plan. |
| Key Replacement | 鍵交換費用 | ¥15,000–¥25,000 | Never | You pay for new locks. Standard practice. Non-negotiable in most cases. |
| Admin/Setup Fee | 事務手数料 | ¥10,000–¥30,000 | Never | Sometimes charged by management company. Negotiable — push back. |
| First Month's Rent | 月額賃料 | 1 month (pro-rated) | N/A | Pro-rated from your move-in date. |
| Total Range | — | 3–6× monthly rent | — | On an ¥80,000/mo apartment: ¥240,000–¥480,000 upfront. |
Worst Case vs. Optimized — Real Numbers
Using an ¥80,000/month apartment as our example:
The difference: ¥379,000 — nearly 5 months' rent — just by knowing what to look for and negotiate.
How to Find Zero Key Money Apartments
礼金ゼロ (rei-kin zero) apartments have become increasingly common, especially in Osaka and suburban Tokyo. Here's how to find them:
- Filter explicitly for 礼金0 on SUUMO, HOME'S, or Best-Estate.jp
- Newer buildings (after 2010) are more likely to have zero key money
- Osaka and Kansai generally have fewer key money requirements than Tokyo
- Landlords with high vacancy rates are often willing to waive key money
- Move in off-peak season (May–August, November–December) for more negotiating power
💡 Fire Insurance: Use Your Own
Agencies will present their affiliated insurance plan as mandatory. It's not. You are legally entitled to choose your own fire insurance, as long as it meets minimum coverage requirements. Cheaper options (Rakuten Insurance, Cheers Insurance) run ¥10,000–¥15,000 for 2 years vs ¥25,000–¥30,000 for agency-pushed plans. Just tell the agency "I'll arrange my own insurance" before signing.
Tokyo vs. Osaka: Cost Comparison

| Deposit | 1–2 months typical | 1 month typical |
| Agency fee | 1 month standard | 1 month standard |
| Total move-in (typical) | 4–6× monthly rent | 3–4× monthly rent |
| Zero key money availability | Growing (especially suburban) | Widely available |
What You Pay When You Leave
Move-out costs are a common source of disputes. Japan's guidelines (国土交通省ガイドライン) specify what tenants are and aren't responsible for:
- Tenant responsibility: Damage you caused (holes, stains, burns), excessive dirt beyond normal use
- Landlord responsibility: Normal wear and tear, fading from sunlight, scuffs from furniture placement
- Always photograph every mark and damage when you move IN and share with the agency
- Request an itemized breakdown of any deposit deductions — don't accept vague "cleaning fee" charges
- If disputed, you can contact the Japan Housing Finance Agency (住宅金融支援機構) or file a small claims court case
