Guarantor Company vs Personal Guarantor: Why Tokyo Now Wants Both
Why are Tokyo landlords asking for both a guarantee company AND a personal guarantor?
On this page 7
TL;DR: Many Tokyo landlords — particularly in high-demand neighborhoods — now require both a corporate guarantee company and a personal guarantor. This is a recent shift, and it hits foreign applicants hard because we can usually satisfy one but rarely both. Understanding why landlords do this and how to negotiate it is worth the 8 minutes this article takes.
The lease contract for a 1LDK in Daikanyama that I reviewed for a client last October ran to 34 pages. Standard forms have gotten longer. Buried on page 11 was the line that ended up costing three weeks and almost cost the apartment: both a personal guarantor and a guarantee company required.
Both. Required.
My client — a French national, five years in Japan, JLPT N2, solid employment — had the guarantee company locked. Casa had approved him without drama. He did not have a personal guarantor. His Japanese coworkers were friendly but not “stake my credit rating on you” friendly. His wife was French. His parents were in Lyon.
We spent two weeks finding a solution. We did find one. The path wasn’t obvious, and most agents wouldn’t have known to look for it.
Why the Double Guarantor Arrangement Emerged
For most of the 2000s and 2010s, the guarantee company replaced the personal guarantor. Landlords accepted one or the other. The logic was sound: a corporate guarantor with actual capital is more reliable than a cousin who earns ¥3 million a year.
Two things changed.
First, several mid-size guarantee companies went bankrupt or had major payout crises between 2015 and 2022. Landlords who’d been relying on one company found themselves with no coverage and a defaulting tenant. Trust in guarantee companies as a complete solution eroded.
Second, the high-end rental market tightened. In central Tokyo neighborhoods — Minami-Aoyama, Daikanyama, Hiroo, Azabu-Juban, parts of Shibuya — vacancy rates for quality units have stayed low. Landlords in these neighborhoods have negotiating power. They’ve started adding requirements that tenants in a looser market could reject.
The result: double-stacking. Guarantee company for the landlord’s financial protection. Personal guarantor as what one property manager described to me, without irony, as “the human layer.”
What “The Human Layer” Actually Means
When I pushed that property manager on what a personal guarantor adds if there’s already a guarantee company in place, she was direct: it’s not about money. The guarantee company is the financial backstop. The personal guarantor is about accountability.
Her reasoning: tenants who have a Japanese person vouching for them behave differently. There’s a social contract. The guarantor will call. The guarantor will help mediate noise complaints. The guarantor is a real-world connection to Japanese social norms. The guarantee company is just a policy.
I disagree with this reasoning on its merits — a professional guarantee company is a better financial protection mechanism than a salaryman guarantor. But the landlord’s emotional logic is real. Disagreeing with it in the middle of a transaction costs you the deal.
Foreigner Impact: Where This Double Requirement Bites
Foreign applicants can usually satisfy the guarantee company requirement given the right profile (stable income, reasonable visa situation, no credit problems in Japan). Very few can satisfy a simultaneous personal Japanese guarantor requirement.
Your Japanese coworker network almost never materializes here. People are aware of what being a personal guarantor means. They’ll be polite about declining. You won’t have a real conversation where they explain why — you’ll get a slightly longer silence, a “chotto kangaeta n desuga…” and then a graceful pivot.
Realistic paths forward:
Option 1: Employer guarantor. Some Japanese companies, particularly those with large foreign employee populations, will act as institutional guarantors for their employees’ housing. This requires HR involvement and a formal request. Doesn’t work at small companies and requires the company to have a policy in place. Ask HR explicitly; most foreign employees never do.
Option 2: Real estate agency guarantor. Some agencies — not many, but some — will offer a guarantor service for an additional fee. They’re stepping into the personal guarantor role commercially. Fees are typically around ¥30,000–¥60,000 upfront plus an annual fee. Agencies that specialize in foreign tenants are more likely to offer this.
Option 3: Second guarantee company. Some landlords will accept two guarantee companies instead of a company plus a personal guarantor. This requires finding a landlord and agent open to the substitution, and a second guarantee company willing to take a secondary position. Unusual but not impossible.
Option 4: Negotiate the requirement away. Works only with individual owner-operators, not managed properties. The ask: “We understand your concern about communication and continuity. Can we replace the personal guarantor requirement with [a larger security deposit / a quarterly check-in commitment / a bilingual emergency contact]?” This requires the right agent and the right landlord. More successful in neighborhoods where vacancy is higher.
What Guarantee Companies Actually Cover vs. What Personal Guarantors Cover
Guarantee companies cover:
- Unpaid rent (typically immediately, without court action)
- Legal costs if eviction is required
- Restoration costs for ordinary damage (above normal wear)
- Some companies cover lock changes and key recovery
Personal guarantors nominally cover the same things but in practice:
- Payment requires the landlord to take legal action against the guarantor
- Recovery is slower and more uncertain
- The guarantor may not have the funds even if they have the obligation
- Social pressure from the guarantor toward the tenant is the real mechanism
In terms of pure financial protection, the guarantee company is superior. When you’re negotiating with a landlord, this argument is available to you — though few agents will make it unprompted.

The Price Tag of Double Guarantor Requirements
When you’re already paying:
- Guarantee company fee: 0.5–1.0x one month’s rent (upfront)
- Annual guarantee renewal: around ¥10,000–¥20,000
Adding a commercial guarantor service from an agency means another roughly ¥30,000–¥60,000 upfront plus ongoing fees.
On a ¥180,000/month apartment in Hiroo, your guarantee costs alone at move-in could be ¥150,000–¥240,000 before you’ve counted key money, security deposit, or agent fees.
Real money. Also the tax foreigners pay for operating without the social infrastructure the system was designed for.
Where This Goes Wrong
- Assuming the double requirement is fixed and not negotiable. The right ask to the right landlord at the right vacancy moment has moved this requirement before.
- Not asking HR whether your employer offers an institutional guarantor arrangement. This question is asked rarely. When the answer is yes, it changes everything.
- Accepting the agent’s first “that’s required” without asking why. Agents sometimes communicate landlord preferences as requirements. They’re not always identical.
- Ignoring the alternative: there are large numbers of listings that don’t require a personal guarantor. Searching specifically for listings that note guarantee company only (hosho gaisha nomi) is a legitimate filter. Not all portals display this, but your agent can filter for it in their MLS access.
- Paying for a commercial guarantor service without confirming the landlord accepts it as a personal guarantor substitute. Get written confirmation through your agent before paying the fee.
FAQ
Q: How common is the double guarantor requirement in Tokyo? Increasingly common in central neighborhoods (Minato, Shibuya, Meguro wards), less common in outer wards (Nerima, Adachi, Katsushika). As a rough directional estimate, somewhere around 20–30% of quality listings in sought-after areas now include it, up from negligible in 2018.
Q: Is the double requirement applied more often to foreign applicants? Some landlords and management companies apply it to all applicants as standard policy, so it’s not always targeted. But some apply it selectively — and foreigner applicants are more likely to get the strict version. No way to prove this on a case-by-case basis.
Q: Can my Japanese spouse be my personal guarantor? Yes, and this is the most common solution for foreigners in binational couples. Confirm with your agent that the landlord will accept a spouse in this role — some prefer a guarantor who isn’t a co-inhabitant, but many accept it.
Q: If I find a guarantor company that offers the personal guarantor service, does the fee go on top of the first guarantee company fee? Yes. Two separate fees. Budget for both.
Q: Is there a list of agencies that offer commercial personal guarantor services? No published list exists as far as I know. Ask foreign-tenant-specialist agencies directly: Sakura House, Global Housing Tokyo, Fontaine, and HousingJapan all have agent staff who know the workarounds. Ask specifically: “If a landlord requires a personal guarantor and I don’t have one, what options do you offer?”
