Why don't share houses require joint guarantors or guarantor company enrollment?

This guide clarifies the structural fundamentals foreign residents should understand.

In 2026, rental properties and services that require neither a guarantor nor a guarantor company are increasing. We comprehensively compare guarantor-free options including UR rental housing, public housing, share houses, and monthly mansions.
The 2020 revision of the Civil Code brought major changes to the joint guarantor system in rental agreements. Experts explain practical methods for renting without a guarantor, including how to use guarantor companies and find properties that don't require one.
Explains the role of "guarantors" required in Japanese rental contracts and practical alternatives available to foreign residents without Japanese guarantors (guarantor companies, UR rental housing, and properties welcoming foreign residents).
Anyone considering a share house has likely seen nearly every listing advertise "no guarantor required" and "no guarantor company enrollment required." By contrast, standard rentals almost universally require either a joint guarantor or guarantor company enrollment. Why do only share houses waive this requirement?
The answer isn't "because they're generous"—it's because the contract structures and operating models are fundamentally different. This article explains these mechanisms from legal and economic perspectives, helping foreign residents understand the true nature of share houses.
In Japan, standard rentals (standard leases) protect tenants heavily under the Building and Land Lease Act. Landlords cannot evict tenants immediately for nonpayment; instead, they must follow a lengthy process: certified notice → accumulation of three months or more of unpaid rent → demand for payment → eviction lawsuit → forced eviction. During this time, lost income can reach 6–12 months of rent.
Joint guarantors and guarantor companies exist to cover this risk. If a tenant defaults, the guarantor makes a substitute payment, minimizing the landlord's loss. Foreign residents often cannot secure a guarantor, so guarantor company enrollment (initial fees of 50–100% of monthly rent) becomes the alternative.
Foreign nationals have short credit histories in Japan, minimal tax payment records, and limited employment tenure, leaving landlords unable to assess their nonpayment risk clearly. Guarantor company screening helps fill this gap.
Most share houses use either a "facility use agreement" under civil law or a short-term fixed-term lease.
Since facility use agreements fall outside the Building and Land Lease Act, operators can remove rule violators relatively quickly. This structurally lowers nonpayment risk, eliminating the need for guarantor protection.
Share houses typically require a ¥30,000–¥100,000 deposit at move-in. While similar to security deposits in standard rentals, the primary purpose here is immediate offset against nonpayment—not restoration costs. If one or two months of rent go unpaid, the operator's loss remains manageable within the deposit range.
Share house operators manage 10–30 residents per building, generating ¥600,000–¥2 million monthly revenue. When one resident defaults, overall impact is only 3–5%, easily absorbed by the operator's cash flow without guarantor company support. By contrast, private landlords renting single units face major losses from even one default.
Share house operators complete screening using government ID (residence card or passport), basic income verification, and an interview. For those with credit cards, they require automatic monthly withdrawal agreements, internalizing the collection process to ensure timely payment at month's start.
Guarantor company screening for standard rentals takes 2–5 business days, and document gaps (pay stubs, residence cards, etc.) can cause 2+ week delays. Many share houses let you tour, sign, and move in on application day, making urgent relocations and arrivals much easier.
Standard rentals typically require at least one year remaining on a residence card (guarantor company standard). Many share houses accept contracts for stays as brief as three months, accommodating short-term assignments and study abroad.
Many share houses collect monthly fees via credit card auto-withdrawal. Some operators accept international credit cards (Visa, Mastercard), allowing those without Japanese cards to move in.
Standard rentals require a domestic emergency contact (family, friend, or workplace), but share houses often accept overseas family contacts instead. This is a major advantage for foreigners without connections in Japan.
The convenience of waiving guarantors comes with risks different from standard rentals.
Facility use agreements and fixed-term leases allow 14–30 day notice for rule violations (noise, smoking, overnight guests, violence, etc.). Tenant protections here are weaker than in standard rentals.
Fixed-term leases end automatically when the period expires; renewal depends entirely on the operator's decision. Even if you want to stay, renewal may be denied.
Verify deposit return conditions in the contract and research operator credibility (reviews, years in business) beforehand. Some newer share house operators have experienced deposit return disputes.
Share houses' "no guarantor required" isn't just marketing—it's the result of four integrated systems: contract structures (facility use agreements and fixed-term leases), deposit systems, operators' risk distribution models, and independent screening criteria.
For foreign residents, share houses offer a powerful option bypassing three obstacles—credit history, guarantors, and residence duration—yet come with trade-offs like quick eviction notices and uncertain renewal. For short to mid-term stays, they're an excellent choice; for long-term settlement, consider transitioning to standard rentals later. Use share houses strategically as your "gateway to life in Japan."
