If you are searching for an apartment in Japan, you have almost certainly run into the question of a family guarantor vs. guarantee company in Japan. Most landlords require one or the other before they hand over the keys — and choosing the wrong path can slow down your move or even cost you a rental application. The good news: once you understand how each option works, the right choice for most foreign residents becomes clear. We will walk you through both options honestly so you can move forward with confidence.
The Short Answer: Which Should Most Foreign Residents Choose?
For the majority of foreigners living in Japan, a guarantee company (hoshō gaisha) is the more practical and realistic choice. Finding a Japanese family member or permanent resident willing to act as guarantor is difficult for most newcomers, and many landlords now require a guarantee company regardless. That said, there are situations where a family guarantor still makes sense — read on to see which applies to you.
What Is a Family Guarantor in Japan?
A family guarantor (連帯保証人, rentai hoshōnin) is a person — usually a family member or close acquaintance — who legally agrees to pay your rent if you cannot. In Japan, this role carries serious legal weight. The guarantor is jointly liable, meaning the landlord can go directly to them for unpaid rent, repair costs, or other damages without first chasing you.
Who Qualifies as a Family Guarantor?
- Must be a resident of Japan (Japanese citizen or long-term visa holder with stable income)
- Must have a stable, verifiable income — landlords will check this
- Must provide identity documents, proof of income, and a personal seal (hanko) or signature
- Is typically a parent, sibling, or spouse living in Japan
Pros of Using a Family Guarantor
- No monthly or upfront fee — you pay nothing to a third party
- Can strengthen your application if the guarantor has strong financial credentials
- Some older landlords or smaller buildings still prefer or accept this arrangement
Cons of Using a Family Guarantor
- Most foreign residents simply do not have a qualifying family member in Japan
- Many landlords and property management companies now require a guarantee company regardless
- Puts significant financial and legal pressure on the person agreeing to guarantee — relationships can suffer if problems arise
- The paperwork process can be slower and more complicated
What Is a Guarantee Company in Japan?
A guarantee company (保証会社, hoshō gaisha) is a private business that acts as your guarantor for a fee. You pay them, they assure the landlord that rent will be covered if you default, and the landlord gets peace of mind. This system has become the standard across Japan, especially in larger cities, and many property management companies work exclusively with specific guarantee companies.
How Guarantee Companies Work for Foreign Residents
Some guarantee companies specialize in supporting foreign residents and accept applicants with shorter residency histories, non-Japanese names, or limited Japanese. Companies such as GTN (Global Trust Networks) are well known for this. Always confirm directly with the company whether they accept your visa type and nationality, as policies vary and change.
Typical Costs (Guide Only — Confirm with the Provider)
- Initial fee: Roughly 0.5 to 1 month's rent, paid at move-in (this is a general guide; amounts differ by company)
- Annual renewal fee: Often around 10,000 yen per year, though this varies widely
- Some companies charge a flat fee; others use a percentage-based model
Always ask your real estate agent for the exact fee schedule before signing anything, and check the guarantee company's official website for the latest figures.
Pros of Using a Guarantee Company
- No need to find a Japanese guarantor — ideal for most foreign residents
- Widely accepted (and often required) by landlords across Japan
- Some companies offer multilingual support, making the process far less stressful
- Faster application process in many cases
- Foreign-friendly companies can help even if your credit history in Japan is short
Cons of Using a Guarantee Company
- There is a cost — the initial fee and renewal fees add up over time
- If you miss rent, the company pays the landlord but then pursues you for repayment — it is not a free pass
- Not all guarantee companies accept all visa types; some may reject certain nationalities or short-stay visa holders
Family Guarantor vs. Guarantee Company: Side-by-Side Comparison
| Factor | Family Guarantor | Guarantee Company |
|---|---|---|
| Cost | Free (no fee to a third party) | Initial fee + annual renewal fee |
| Availability for foreigners | Difficult — need a qualifying resident in Japan | Widely available, including foreign-friendly options |
| Landlord acceptance | Declining — many now require a guarantee company | Standard and widely required |
| Application speed | Can be slower due to paperwork | Often faster and more streamlined |
| Language support | Depends on the guarantor | Some companies offer English or multilingual support |
| Risk to personal relationships | High — guarantor is jointly liable | None — commercial relationship only |
| Best for | Those with a willing, qualifying resident in Japan | Most foreign residents, especially newcomers |
How to Choose: A Simple Decision Guide
- Do you have a family member or close friend in Japan who has stable income, is a long-term resident, and is genuinely willing to take on legal liability? If yes, ask your real estate agent whether the landlord accepts personal guarantors — some still do.
- Is the landlord or management company requiring a specific guarantee company? In that case, the decision is made for you — use their preferred provider.
- Are you new to Japan or do you have a short residency history? A foreign-friendly guarantee company like GTN is likely your smoothest path.
- Are you worried about the cost? Factor the guarantee fee into your total move-in budget alongside the deposit and key money — it is a standard part of renting in Japan today.
Documents You Will Likely Need
Requirements differ between landlords and guarantee companies, but prepare these as a starting point:
- Residence card (Zairyu Card)
- Passport
- Proof of income (pay slips, employment certificate, or tax documents)
- Bank statements (some companies request these)
- Emergency contact details
If using a personal guarantor, they will need to submit their own income and identity documents as well. Always confirm the exact document list with your real estate agent or guarantee company early in the process.
Summary: Making the Right Choice for Your Situation
The family guarantor vs. guarantee company decision in Japan is not as complicated as it first seems. For most foreign residents — especially those who are new to Japan or do not have a qualifying guarantor already living here — a guarantee company is the practical, reliable, and widely accepted solution. Yes, it comes with a fee, but it removes a major barrier and keeps the rental process moving.
If you do have a trusted person in Japan who qualifies and is willing to take on the responsibility, it is worth asking your agent whether the landlord accepts personal guarantors — you may save on fees. But never pressure a friend or family member into this role lightly; the legal obligations are real and significant.
Take it one step at a time: talk to your real estate agent early, confirm what the landlord requires, and then gather your documents. Thousands of foreign residents successfully rent apartments in Japan every year — you can absolutely do this too.
