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.

CostJapanese TermTypical AmountRefundable?Notes
Deposit敷金 (Shikikin)1–2 months' rentPartiallyReturned minus cleaning & repair costs. Negotiate itemized deductions when leaving.
Key Money礼金 (Reikin)0–2 months' rentNeverA gift to the landlord. Historically mandatory, now negotiable or zero in many cases.
Agency Fee仲介手数料1 month + 10% taxNeverLegally 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/yearNeverIncreasingly mandatory. Fee varies by company and visa type.
Fire Insurance火災保険¥15,000–¥30,000 / 2 yearsNeverMandatory but you can choose your own insurer. Don't accept the agency's overpriced plan.
Key Replacement鍵交換費用¥15,000–¥25,000NeverYou pay for new locks. Standard practice. Non-negotiable in most cases.
Admin/Setup Fee事務手数料¥10,000–¥30,000NeverSometimes charged by management company. Negotiable — push back.

Total Range3–6× monthly rentOn 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:

Worst Case
Standard Tokyo apartment, everything maxed
Deposit (2 months)¥160,000
Key money (2 months)¥160,000
Agency fee (1 month + tax)¥88,000
Guarantor company fee¥80,000
Fire insurance (agency plan)¥30,000
Key replacement¥25,000
Admin fee¥30,000
First month rent¥80,000
Total¥653,000
Optimized
Zero key money, own insurance, Osaka or suburban Tokyo
Deposit (1 month)¥80,000
Key money (zero)¥0
Agency fee (half month)¥44,000
Guarantor company fee¥40,000
Own fire insurance¥12,000
Key replacement¥18,000
Admin fee (waived)¥0
First month rent¥80,000
Total¥274,000

The difference: ¥379,000 — nearly 5 months' rent — just by knowing what to look for and negotiate.

💡 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.
