Do I Need a Guarantor to Rent an Apartment in Japan?
This guide is for foreign residents in Japan looking for an apartment who are worried about the "guarantor" (保証人) requirement — especially those without Japanese family or friends who could act as a personal guarantor.
Traditionally, yes — Japanese rental contracts have long required a guarantor (保証人), historically a Japanese relative or friend. In practice today, most landlords accept a guarantor company (保証会社) instead — a private company that, for a fee (commonly around 0.5–1x one month's rent, sometimes with an annual renewal fee), formally takes on this role. Some properties marketed as "guarantor not required" (保証人不要) skip this entirely, usually with the cost built into rent or deposit instead. Separately, almost all contracts also ask for an emergency contact (緊急連絡先) — which is a different, much lower-stakes requirement that's usually fine to fill with a friend, colleague, or employer.
- Guarantor companies (保証会社) are now the standard solution for foreign renters — you almost never need to find a Japanese person willing to be a personal guarantor
- Typical guarantor company fee: 0.5–1x monthly rent upfront, sometimes with annual renewal fees
- You usually don't choose the guarantor company — the landlord/agent designates it based on the property
- "Guarantor" and "emergency contact" are different things — the emergency contact doesn't take on financial liability
- Your visa type and remaining period can affect which guarantor companies will approve you, similar to bank accounts and credit cards
Personal Guarantor vs Guarantor Company
Under Japan's 2020 Civil Code reform, personal guarantee contracts (連帯保証人) for individuals must specify a maximum liability amount (極度額) — an open-ended personal guarantee is no longer valid. Guarantor companies, as corporate entities, aren't subject to this individual-protection cap in the same way and routinely formalize the guarantee as a service.
For nearly all foreign renters without Japanese family in Japan, the practical path is a guarantor company — you generally don't need to find a personal guarantor at all. Some properties in central areas now require both a guarantor company and a personal co-signer, which is the harder case; in that situation, ask your agent specifically about "guarantor not required" (保証人不要) listings or shared housing as alternatives.
How Guarantor Companies Work in Practice
- You apply for a property through a real estate agent
- The agent forwards your application to the guarantor company designated by the landlord — you typically don't choose it
- The company reviews your income, employment stability, and visa status (and sometimes credit history)
- If approved, you pay the initial guarantor fee at lease signing; some companies bill annual renewal fees directly to you afterward
- If denied, your agent may try a different guarantor company for the same or a different property — some companies are more accommodating to foreign residents than others
Guarantor vs Emergency Contact — Don't Confuse These
| Guarantor (保証人/保証会社) | Emergency Contact (緊急連絡先) | |
|---|---|---|
| Financial liability? | Yes — covers unpaid rent/damages if you default | No — just a contact point |
| Who can be one? | A guarantor company (usual), or occasionally a qualifying individual | Almost anyone — friend, colleague, employer |
| Cost? | Yes, typically 0.5–1x rent + possible annual fees | No |
📋 Common Scenarios
This is the standard case guarantor companies exist for. Work with a real estate agent experienced with foreign tenants; they'll handle the guarantor company application as part of the normal process. Budget the guarantor fee (roughly 0.5–1x rent) into your move-in costs alongside deposit, key money, and agent fees.
This combination has become more common, especially in central Tokyo. If you don't have a personal co-signer option, ask your agent for properties marked "guarantor not required" (保証人不要) or consider shared housing (シェアハウス), which often skips the guarantor requirement entirely.
Similar to bank accounts and credit cards, some guarantor companies are more cautious with short remaining visa periods. If declined by one company, your agent may be able to try another that's more accommodating — this is a normal part of the process, not a sign of a fundamental problem.
🚫 Common Mistakes
This is rarely the case anymore — guarantor companies have largely replaced personal guarantors for foreign renters.
These have very different implications. An emergency contact takes on no financial responsibility and can usually be a friend or colleague.
This fee is in addition to deposit, key money, and agent fees — factor it into your total move-in budget from the start.
