Let's be honest: the guarantor requirement is one of the most frustrating barriers foreigners face when apartment hunting in Tokyo. You've found the perfect place, you have a stable job, and you can easily afford the rent—but without a Japanese citizen willing to vouch for you financially, many landlords won't even consider your application.
The good news? The Tokyo rental market has evolved significantly, and there are now multiple legitimate ways to secure an apartment without knowing a single Japanese person willing to be your guarantor. This guide covers every option available in 2026, with real costs, honest assessments, and practical strategies that have helped thousands of foreigners find homes in Tokyo.
Understanding Why Tokyo Requires Guarantors
Before diving into solutions, it helps to understand why this system exists. In Japan, a guarantor (保証人, hoshounin) serves as a financial safety net for landlords. If a tenant can't pay rent, damages the property, or disappears, the guarantor becomes legally responsible for covering all costs.
For Japanese tenants, this traditionally meant asking a parent or close relative. But for foreigners—especially those new to Japan—finding someone willing to take on this significant legal responsibility is nearly impossible. Your Japanese coworker might be friendly, but asking them to potentially cover months of your unpaid rent? That's a big ask.
This created a genuine barrier that locked many foreigners out of the regular rental market for decades. Fortunately, the rise of guarantor companies and changing attitudes among landlords have dramatically improved the situation. Today, approximately 85% of Tokyo landlords accept guarantor companies as an alternative to personal guarantors.

Guarantor Companies: Your Primary Solution
Guarantor companies (保証会社, hoshougaisha) have become the standard solution for foreigners renting in Tokyo. These companies essentially act as your guarantor for a fee, taking on the financial responsibility that would otherwise fall to a personal guarantor.
How Guarantor Companies Work
When you apply for an apartment, the real estate agency will typically require you to also apply with their partnered guarantor company. The guarantor company reviews your application—checking your income, employment stability, visa status, and sometimes credit history—then decides whether to approve you.
If approved, you pay the guarantor company a fee (typically 50-100% of one month's rent), and they guarantee your lease to the landlord. If you ever fail to pay rent, the guarantor company pays the landlord and then comes after you for the money.
Major Guarantor Companies in Tokyo (2026)

💡 Pro Tip: GTN for Foreigners
Global Trust Networks (GTN) specializes in serving foreign residents and offers English support throughout the application process. They're often more lenient with foreigners who have less credit history in Japan, making them an excellent first choice for newcomers.
What Guarantor Companies Check
- Income verification: Typically require income of 3x monthly rent
- Employment status: Full-time employment preferred, but part-time and contract workers can qualify
- Visa status: Longer visa durations are favorable
- Credit history: Some check Japanese credit records if you have history
- Emergency contact: Usually require a contact in Japan

UR Housing: Japan's Best-Kept Secret
UR Housing (Urban Renaissance Agency) operates government-backed rental apartments that genuinely don't require guarantors—not even guarantor companies. This makes them incredibly valuable for foreigners, though they come with specific requirements.
Why UR Housing Is Special
- No guarantor of any kind: Not personal, not company
- No key money: Eliminates a major upfront cost
- No renewal fees: Saves money long-term
- Transparent pricing: What you see is what you pay
- Foreigner-friendly: Equal treatment regardless of nationality
UR Housing Requirements
The catch? UR has strict income requirements:
- Income requirement: Monthly income must be at least 4x the rent (or savings equivalent to 100x monthly rent)
- Valid visa: Your visa must cover the initial contract period
- Japanese documentation: Residence card and ability to read contracts (or bring a translator)
For a ¥80,000/month apartment, you'd need to show monthly income of at least ¥320,000, or savings of ¥8,000,000. This makes UR ideal for established professionals but challenging for students or those just starting their careers.
Finding UR Properties
Visit the official UR website (available in English) or their housing centers throughout Tokyo. Popular UR complexes in accessible areas include:
- Harumi Island Triton (Chuo-ku)
- Hikarigaoka Park Town (Nerima-ku)
