How to Buy or Rent a House in Tokyo as a Foreigner: Working with English-Friendly Realtors
By Ibuki — Affarah Friendly Homes · 2026-08-04
Navigating the real estate market in Greater Tokyo as an expat or foreign buyer can feel like entering a completely different universe. In Western countries, home buyers and renters browse Zillow or open houses independently, contacting dozens of different listing agents. In Japan, however, the real estate industry operates on a centralized, broker-to-broker database called REINS (Real Estate Information Network System).
Whether you are an American remote engineer looking to buy a spacious 4-room detached house (kodate) in the Tokyo suburbs, or a foreign professional searching for a luxury 2LDK apartment in Minato Ward, working with the right English-friendly realtor is your single most important decision.
In this deep-dive guide, we reveal how Japanese real estate agencies operate behind the scenes, how to organize a high-efficiency single-day property tour (Naiki), and the exact checklist of questions to ask before signing.
1. The Secrets of the Japanese Property Market: How REINS Works
In Japan, licensed real estate agencies (Takuten) have direct access to REINS—the official nationwide database managed by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
What REINS means for foreign buyers and renters:
- One Agent Accesses Everything: You do not need to contact 20 different real estate offices across Tokyo. A single licensed bilingual realtor can pull virtually every available rental or purchase listing in Greater Tokyo directly from REINS.
- Pre-Screening Foreign Acceptance: The most critical task your agent performs is calling property management companies on REINS to verify if the owner accepts foreign nationals without Japanese citizenship or permanent residency requirements.
- Fair Market Transparency: Because REINS regulates commission fees by law, legitimate agents charge standardized statutory fees without hidden markups.
| Property Transaction Type | Statutory Agent Fee Cap | Typical Upfront Deposit | Key Financial Prerequisite |
|---|---|---|---|
| Long-Term Rental Lease | 1 Month's Rent + Tax | 3x to 5x Monthly Rent | Institutional Guarantor Company (Hoshōkaisha) |
| Home / Land Purchase (<¥4M) | 4% + ¥20,000 + Tax | 5% to 10% Earnest Money (Teitokukin) | Pre-Approved Mortgage or Cash Funds |
| Home / Land Purchase (>¥4M) | 3% + ¥60,000 + Tax | 5% to 10% Earnest Money (Teitokukin) | Pre-Approved Mortgage or Cash Funds |
2. Organizing a High-Efficiency Property Viewing Tour (Naiki)
If you are flying into Tokyo for a short home-hunting visit or balancing a busy work schedule, your realtor should organize a curated Single-Day Property Tour (Naiki).
Instead of wandering aimlessly between neighborhoods, a professional expat agent compiles a streamlined itinerary:
- Criteria Alignment: Defining your non-negotiables—such as maximum station walking time (e.g., under 10 minutes), layout size (35sqm studio vs 80sqm 3LDK), and school district access.
- Pre-Screening & Calling Landlords: Your agent filters out listings with poor natural light, high highway noise, or restrictive foreign applicant policies.
- Dedicated Viewing Vehicle: Visiting 4 to 6 pre-vetted properties across Tokyo in a single afternoon via private car or efficient train transit.
3. Essential Questions to Ask Your Realtor Before Signing
When walking through candidate homes, ask your agent these critical questions to avoid costly post-move surprises:
For Renters:
- "Is a Japanese private guarantor required, or does the building accept foreign-friendly Guarantor Companies like GTN or Casa?"
- "What is the exact breakdown of initial move-in costs including Key Money (Reikin), Security Deposit (Shikikin), and lock changing fees?"
- "Are there strict building rules regarding pets, musical instruments, or bike storage?"
For Home Buyers:
- *"Is the property built on Freehold Land (Oryōchi) or Leasehold Land (Shakuchiken)?"* (Freehold gives you permanent ownership of the land underneath the building).
- "Was the house built after May 1981 under the modern Seismic Resistance Standards (Shin-Naishin)?" (Crucial for earthquake safety and bank loan approval).
- "Does the property use City Gas (Toshi Gasu) or Propane Gas (Propan Gasu)?" (Propane can increase monthly utility bills by 30%).
