Quick Answer
Renting an apartment in Japan typically costs 4-6 times the monthly rent upfront. For a ¥100,000/month apartment, expect to pay ¥400,000-¥600,000 before moving in — covering deposit, key money, agent fee, guarantor fee, insurance, and first month's rent.

Money Flow When Signing a Lease
💡 Cost-Saving Tips
Look for "0-0" properties (zero deposit, zero key money). Negotiate agent fees — legally they can only charge 0.5 months from the tenant unless you agree otherwise. Move during off-peak months (June-December) for better deals.
⚠️ Disclaimer
Costs vary significantly by region and property. The figures above are Tokyo-area estimates. Consult your real estate agent for exact costs before signing any contract.
