1. What Actually Happens
Your guarantor application was submitted. You waited 3-5 business days. Then the estate agent or landlord tells you: "残念ですが、保証人は却下されました" (Unfortunately, the guarantor was rejected).
You're left in limbo. The landlord won't sign a contract without a guarantor. You can't afford to hire a guarantor company. You're frustrated because you don't understand why your guarantor was rejected—the estate agent gave vague reasons or none at all.
This isn't hypothetical. It happens regularly to foreign workers, students, and expats in Japan. The rejection doesn't come with written explanation. The guarantor may be a Japanese friend, family member of a colleague, or someone from your home country—but if they don't meet the landlord's undisclosed criteria, they're rejected outright.
The clock is ticking. Your current lease ends in weeks, or you need housing urgently for a new job. You're stuck between a locked apartment and unclear rules.
2. Why It Happens
Japan's rental system depends on guarantors because landlords have very few legal protections against problem tenants. Evictions take 6-12 months. Guarantors are the safety net. But there's a hidden gatekeeping layer: landlords and property managers use informal, undisclosed checklists to reject guarantors.
The Unwritten Criteria
Landlords typically reject guarantors for reasons they won't explicitly state:
- Non-Japanese guarantor: A guarantor from your home country (or any non-Japanese person) is rejected automatically at many properties, even if they have excellent income.
- Insufficient income (silent threshold): Your guarantor's income needs to be 30-40× the monthly rent—but many landlords use 50× or higher without saying so. A guarantor earning ¥2.5 million/year might look sufficient but gets rejected silently.
- Self-employed guarantor: Business owners, freelancers, and anyone without stable employment (even if profitable) are rejected frequently because the income isn't "stable" by landlord standards.
- Guarantor has no fixed address: If the guarantor is living abroad, renting, or moving around, rejection is nearly automatic.
- Age limits (usually unstated): Guarantors over 70-75 are rejected by many properties. Guarantors under 20 are rejected by most.
- Guarantor has rental debt or judgment: Any negative credit history, even minor, causes rejection—but the estate agent won't tell you this is the reason.
- Property manager's gatekeeping: Some managers reject foreign guarantors simply because they don't want to deal with potential language barriers or because "the landlord prefers Japanese guarantors" (often racial discrimination, though never stated).
Why this matters: The rejection isn't because the guarantor is actually unsuitable. It's because the system is stacked toward a very narrow profile: employed, Japanese, middle-aged, homeowning guarantors. Anyone outside that profile faces silent rejection.
3. Common Mistakes Foreigners Make
You contact the same estate agent and ask if a different guarantor would work. They say yes, so you ask your friend instead. But if the first guarantor failed due to age, employment type, or being non-Japanese, the second one will too. The estate agent won't diagnose the real problem.
Real cost: Multiple rejections, wasted time, deposit forfeiture if timeline runs out.
Most estate agents give verbal rejections. You leave the conversation with assumptions, not facts. Different staff members may give different reasons, or the reason changes each time you call.
Real cost: You chase the wrong solutions (e.g., finding a higher-income guarantor when the actual problem is the guarantor is non-Japanese).
You think guarantee companies cost ¥100,000+. Some do. But crisis services and budget guarantee firms cost ¥30,000-50,000 and will accept applications other companies reject. You haven't priced them yet.
Real cost: Staying stuck instead of paying for a professional solution that takes 1-2 days to arrange.
You assume if one apartment is rejected, another in the same building will be different. Usually, the same property manager handles all units and uses the same criteria. You'll get rejected again, and now you've used up time and paid multiple application fees.
Real cost: Lost application fees (typically ¥10,000-30,000 per attempt), lost time, and reduced options if you finally need to switch properties.
The estate agent who rejected your guarantor works with specific landlords. A different agent works with different landlords who may have different criteria. Staying with the same agent locks you into the same rejection pattern.
Real cost: Repeated rejections and missing properties that would have accepted your guarantor.
4. Step-by-Step Fix
1Call the estate agent and request written rejection reason
Don't accept a verbal explanation. Say (in Japanese or English): "保証人が却下された理由を文書で説明してもらえますか？" (Can you provide a written explanation of why the guarantor was rejected?)
Many agents will resist. Persist. Say you need it to address the issue and find a solution. If they refuse to provide written reason, escalate to the property manager or landlord directly (ask for the 物件管理者 or 大家). Document the date and time of your call.
Expected outcome: You get 1-3 reasons (e.g., "guarantor age exceeds 70," "non-resident guarantor not accepted," "income insufficient").
2Diagnose which barrier caused the rejection
Match the stated reason to the actual problem:
- If reason: "guarantor non-Japanese" → Go to Step 3 (guarantor company) or Step 5 (new estate agent)
- If reason: "guarantor age / income / employment" → Go to Step 3 (guarantor company)
- If reason: "guarantor lives outside Japan" → Go to Step 3 (guarantor company) immediately
- If no clear reason given → Assume hidden discrimination. Go to Step 5 (new estate agent)
3Contact a guarantor company immediately
This bypasses the personal guarantor requirement entirely. The guarantor company guarantees payment to the landlord. You pay a one-time fee (typically 30-50% of monthly rent) or a monthly fee (3-5% of rent).

Expected timeline: 2-5 business days for approval.
4If guarantor company is rejected, escalate to landlord
Some landlords (rare, but it happens) refuse to accept guarantor companies. This is usually because the landlord is older or prefers direct relationships. In this case:
- Ask the estate agent to explain the landlord's objection in writing.
- Ask if a different guarantor company would be acceptable.
- Offer an increased deposit (礼金 or 敷金) in exchange for waiving the guarantor requirement. Some landlords will accept this.
- If all fails, abandon this property and move to Step 5.
5Switch to a different estate agent and start new applications
The same estate agent will keep showing you properties with the same restrictive landlords. Use a different agent, preferably one specializing in foreigner rentals:
- Tokyo: GaijinPot Apartments, Real Estate Japan, Leopalaces
- Osaka/Kansai: Leopalaces, Real Estate Osaka
- Nationwide: Suumo (filter by "外国人対応" = foreigner-friendly)
When submitting new applications, clearly state: "需要に応じて保証人会社の利用を提案できます" (We can arrange a guarantor company if needed). This signals you're prepared and reduces delays.
Expected outcome: Different properties, different landlords, higher acceptance rate.
Critical point: If you proceed with Step 3 (guarantor company) while still trying Step 5 (new agent), inform both agents clearly. Do not submit multiple guarantor applications to the same property—this causes confusion and may trigger additional rejections.

6. City & Region Differences
Tokyo
What's different: Landlords are more accustomed to foreign tenants and guarantor companies. Many central ward properties (Shinjuku, Minato, Shibuya) have explicit "外国人対応" (foreigner-friendly) policies. Guarantee companies are abundant and competitive. Rejection reasons are more often stated explicitly.
Better option: Guarantor company. Processing time: 2-3 business days. Cost: ¥35,000-60,000 typically.
Gotcha: Central Tokyo properties still use age/income/employment gatekeeping. If rejected on these grounds, a guarantor company won't help—the issue is the landlord's criteria, not the lack of a guarantor.
Osaka / Kansai Region
What's different: Landlords are less experienced with foreign tenants. Personal guarantor requirements are more strictly enforced. Guarantor companies are available but fewer options than Tokyo. Estate agents may pressure you more to find a Japanese guarantor.
Better option: Guarantor company + switch estate agents to larger chains (Apaman, Leopalaces). Processing time: 3-5 business days. Cost: ¥40,000-75,000 typically.
Gotcha: Some Osaka landlords reject guarantor companies entirely if they've had bad experiences. Escalation to landlord directly often helps, or offer a higher deposit (up to 3× rent as 敷金).
Kyoto
What's different: Very traditional rental market. Personal guarantor is strongly preferred. Many properties are old houses (nagaya) or small units managed by individual landlords who don't trust corporate guarantors. Foreigner acceptance is lower than Tokyo/Osaka.
Better option: Find a new property through a major chain agent (Apaman, Century 21). Accept higher deposits/礼金. Consider arranged housing through your employer or university.
Gotcha: Some Kyoto landlords will accept short-term furnished rentals (月単位) without guarantor because tenancy is so brief. Use CrossOneRoom or similar if you need immediate housing.
Fukuoka
What's different: Mid-tier market. Less guarantor automation than Tokyo, more flexible than rural areas. Guarantor companies less common; personal guarantor still standard but rejection criteria are less rigid.
Better option: Try local guarantee companies or 福岡不動産 (Fukuoka Real Estate). If rejected, escalation and negotiation often work—landlords are more willing to discuss terms.
Gotcha: Guarantor companies may take 5-7 days. Plan ahead.
Rural Areas (Nagano, Yamanashi, Shikoku)
What's different: Personal guarantor is usually non-negotiable. Guarantor companies rarely used. Many landlords have never rented to foreigners. Estates agents are small and don't specialize in foreigner rentals.
Better option: Seek housing through your employer, university, or organization. Contact a large national agent (Apaman, Leopalaces) instead of local agents. Be prepared to accept unfavorable terms (higher deposit, restricted move-in dates).
Gotcha: Rejection is common regardless of guarantor quality. If rejected, it may be due to foreigner status, not the guarantor.
