When browsing Japanese real estate portals like SUUMO, LIFULL HOME'S, or at home, every international resident faces the same confusing question: "How much will I actually need to pay upfront to sign the lease for this apartment?"
While portal listings display basic numbers like "Rent: ¥85,000 / Management: ¥8,000 / Deposit: 1 month / Key Money: 0 month," they never show the true total invoice amount. Mandatory closing costs—such as advance rent, pro-rated daily rent, guarantor company fees, fire insurance, lock replacement fees, and agency brokerage fees—are often omitted from the main display.
Worse, asking traditional agencies often leads to aggressive sales calls and demands for store visits before you even get a transparent quote. To eliminate this friction, Sorai Tokyo developed the Initial Move-in Cost Simulator—designed for international renters seeking clear, upfront answers without the hassle.

1. Why Portal Listings Don't Show the Full Move-in Cost
Major Japanese real estate portals list hundreds of thousands of apartments registered by countless brokerage firms. However, there is a fundamental "information gap" between surface-level numbers and the real contractual costs in Tokyo.
1-1. Mandatory Closing Costs Not Highlighted on Portals
- Advance Rent & Pro-rated Daily Rent (Mae-yachin & Hiwari-yachin): In Japan, rent is paid one month in advance. If your lease starts mid-month, you pay the remaining days of that month plus the entire following month upfront (~1.5 to 2 months' rent).
- Guarantor Company Initial Fee (Hoshogaisha Hiyou): Over 90% of Tokyo rental apartments require a guarantor company regardless of whether you have a Japanese cosigner. The standard upfront fee is 40% to 50% of total monthly fees (rent + management).
- Renter's Fire & Liability Insurance (Kasai Hoken): Mandatory for all tenants, costing roughly ¥15,000 to ¥20,000 for a 2-year single plan or ¥20,000 to ¥25,000 for families.
- Lock Replacement Fee (Kagi Koukan-dai): Actual cost to replace the lock cylinder before move-in, ranging from ¥16,500 to ¥33,000 for high-security dimple keys.
- Brokerage Agency Commission (Chukai Tesuryo): Legally capped under Japanese Real Estate Law at 1 month's rent + 10% consumption tax.

4. Checklist: How to Spot Unnecessary Add-on Fees on Your Quote
Have you received a quotation from another agency with unfamiliar fee items? In Japan, several optional add-ons are frequently disguised as mandatory requirements. Here is how to identify them:
| Invoice Line Item | Typical Charge | Mandatory or Optional | Licensed Agent Insight & Tips |
|---|---|---|---|
| Room Disinfection / Deodorization | ¥16,500 – ¥22,000 | Generally Optional | Often just an aerosol spray. In most cases, you can ask to decline and remove this fee. |
| 24/7 Emergency Support Package | ¥16,500 – ¥26,400 | Depends on Landlord | Mandatory only if required by building management. If added by the broker, it can often be removed. |
| Document / Admin Fee (Jimu Tesuryo) | ¥11,000 – ¥33,000 | Generally Questionable | Under Japanese law, charging separate admin fees when receiving the full brokerage commission is generally prohibited. |
| Disaster Kit / Fire Extinguisher Set | ¥11,000 – ¥16,500 | Generally Optional | Basic emergency gear is marked up significantly. You can buy certified extinguishers online for much less. |
5. Frequently Asked Questions (FAQ)
How can the simulator calculate initial costs with just a portal URL or screenshot?
It parses key listing terms such as rent, management fees, deposit, key money, and guarantor requirements, then applies standard Tokyo rental market standards and property management cost calculations to generate an accurate estimate and detailed breakdown instantly.
Will there be any difference between the simulation and the official contract invoice?
Yes, minor differences (usually a few thousand to several thousand yen) can occur based on the exact move-in date (pro-rated rent) and specific building insurance or lock change plans. You can easily request an exact final invoice via LINE directly from the results page.
Can I use the simulator if I already received a quotation from another real estate agency?
Absolutely! You can use our simulator as a transparent second opinion to check whether another agency has added unnecessary mandatory options such as expensive deodorization sprays or duplicate administrative fees.
Is the simulator completely free? Do I need to register an account?
It is 100% free with zero registration required. No personal information or email is needed—simply paste the listing URL or text into your web browser for instant results.
