The guarantor requirement is the first serious obstacle most foreigners encounter when trying to rent an apartment in Japan. The traditional system required a 連帯保証人 — a joint guarantor who is a Japanese national, has a stable income, and is willing to be personally liable for your rent if you default or cause damage. Most foreigners arriving in Japan know precisely zero Japanese nationals well enough to ask this of them. The good news is that the system has fundamentally changed in the past decade, and navigating it as a foreigner is more straightforward than the older guides suggest — if you understand which tools are actually available.
Why the Traditional Guarantor System Is Mostly Gone
Since the 2020 amendment to Japan's Civil Code, guarantor company (保証会社) usage has become standard practice for new rental contracts across Japan, not just for foreign tenants. Most landlords and management companies now require a guarantor company rather than a personal guarantor, regardless of whether the applicant is Japanese or foreign. This means foreigners are no longer uniquely disadvantaged by the guarantor requirement — the playing field has leveled, at least on this particular point. The remaining challenge is the income history requirement and the general wariness some individual landlords retain about foreign tenants.
Solution 1: Guarantor Companies That Serve Foreign Residents
The majority of rental listings in Japan now require a guarantor company. Several of them specifically accommodate foreign applicants:
Global Trust Networks (GTN) operates one of the most foreigner-friendly guarantor services in Japan. They accept applicants with Japanese residence cards regardless of nationality, with no requirement for Japanese income history or Japanese credit history. GTN also functions as a real estate portal specifically for foreign residents, sometimes bundling the guarantor service with the lease itself. Their English-language support is reliable.
LEONET is one of Japan's larger guarantor companies and accepts foreign tenants in a significant portion of the buildings they cover. Acceptance rates depend on the individual landlord's contract with LEONET and the specific property.
Cosmos Initia (associated with the Daiwa House group) covers a large number of properties and has processes for foreign applicants with Japanese income documentation.
Standard cost: Guarantor fees typically run 0.5x to 1x the monthly rent as an upfront fee at the time of contract signing, plus an annual renewal fee of ¥10,000-20,000 in subsequent years. On a ¥70,000/month apartment, expect ¥35,000-70,000 upfront for the guarantor service, then ¥15,000-20,000 annually.
Solution 2: Foreign-Friendly Real Estate Agencies
Working with an agency that has experience placing foreign residents dramatically increases your acceptance rate. These agencies know which landlords will consider foreign applicants, how to present your application, and which properties to filter out before you waste time visiting them.
Sakura House has been operating foreigner-oriented share housing and apartments in greater Tokyo for decades. Their inventory leans toward share houses and furnished apartments, which is appropriate for people arriving without furniture. English application support is standard.
Fontaine specializes in furnished apartments and monthly mansion rentals for foreigners in Tokyo and Chiba-area markets. Useful for the transition period before a long-term lease.
Able (エイブル) is a mainstream Japanese real estate chain with dedicated foreigner consultation services at select branches. The Akihabara and Shinjuku branches are particularly experienced with foreign applicants, and some Chiba branches (notably in Funabashi and Chiba City) have staff who handle foreign applications regularly.
Century 21 international desks: Several Century 21 franchise offices in the greater Tokyo area have international service desks staffed with multilingual agents. Quality varies by location — checking reviews specific to the branch is worthwhile.

Solution 3: Monthly Mansions for the First One to Two Months
If you need to secure a place to live before completing your ward office registration or before you have enough Japanese administrative documents assembled for a long-term lease, monthly mansions (マンスリーマンション) are the right bridge solution.
Monthly mansions are fully furnished, utilities-included apartments rented on monthly terms with no key money, no deposit, and no guarantor requirement. They accept foreign residents upon presentation of a passport and, where applicable, a zairyu card. Cost runs ¥60,000-120,000 per month for a one-room studio in the Chiba-to-central-Tokyo corridor. Operators like Monthly Mansion Tokyo, Sakura House, and Leopalace 21 have inventory across the Chiba area.
The trade-off is cost per month relative to long-term rentals, and the lack of a permanent address for purposes like bank account opening (though most monthly mansions will confirm in writing that you are a resident, which many banks accept for account applications).
Documents Required for a Long-Term Lease Application
Landlords and guarantor companies will typically request:
- Passport (copy)
- Zairyu card (copy, front and back)
- Employment contract or letter from employer (showing position, contract type, and monthly income)
- Three months of recent payslips, or a tax certificate if employed for at least one year in Japan
- Bank statement from your Japanese bank account (if you have one — not always required at the earliest stage)
- NHI card or company health insurance card (confirms legal resident status)
If you are a newly arrived foreign resident with no Japanese income history, some guarantor companies will accept an employer guarantee letter or sponsor letter in lieu of payslips. GTN specifically has application paths for new arrivals.
The Full Cost of Moving Into an Apartment
This is where Japan's rental market surprises most foreigners. The initial outlay for a standard unfurnished apartment lease is substantial:
- Deposit (敷金, shikikin): 1-2 months' rent, held as security and partially returned when you move out (deductions for cleaning and repairs vary significantly)
- Key money (礼金, reikin): 0-1 months' rent, paid to the landlord as a gift with no expectation of return — many newer listings, particularly in suburban Chiba, charge zero key money
- Agency fee (仲介手数料): 1 month's rent plus 10% consumption tax, paid to the real estate agency
- Guarantor fee: 0.5-1x month's rent (see above)
- First month's rent: Usually pro-rated based on move-in date
- Fire insurance (火災保険): Required by most contracts; typically ¥15,000-20,000 for a two-year policy
Total initial cost on a ¥70,000/month apartment: roughly ¥280,000-420,000 depending on the key money situation and guarantor fee rate. This 4-6x monthly rent upfront cost is why monthly mansions or guesthouses for the first month make financial sense — they allow you time to save and assemble the funds for a proper lease rather than arriving cash-strapped at signing.
Chiba-Specific Advantages for Foreign Renters
The Chiba rental market is meaningfully more accessible for foreign residents than central Tokyo. Several factors combine:
Higher landlord acceptance rates: Competition for apartments in suburban Chiba is lower than in Tokyo's inner wards. Landlords in Funabashi, Matsudo, Ichikawa, and Chiba City are less likely to reject a well-documented foreign applicant outright because they have fewer alternative applicants. In high-demand central Tokyo neighborhoods, landlords with ten interested applicants can afford to be selective about nationality.
More zero-key-money listings: The 礼金 (key money) system has faded faster in suburban markets. A significant proportion of Chiba rental listings now show 礼金ゼロ, which meaningfully reduces initial outlay.
Larger units at lower rents: The cost-of-living difference between Chiba and Tokyo is covered in detail in the complete cost of living guide for Japan. The practical effect for renters is that your budget buys more space in Chiba, and the lower rent reduces the absolute cost of the security deposit and agency fee even when the ratio is the same.
The expat relocation guide for Chiba covers neighborhood-level specifics, including which areas have the highest concentration of foreign-friendly landlords and which train lines give you the best access to Tokyo.
Red Flags in Rental Contracts
A few contract terms worth scrutinizing:
- Restoration to original condition clauses (原状回復): MLIT guidelines and established dispute resolution practice hold that ordinary wear and tear is the landlord's responsibility. Contracts that try to make tenants responsible for carpet replacement, wall repainting from normal use, or other ordinary aging costs go beyond what this guidance supports. Foreign tenants are sometimes presented with one-sided restoration clauses that would not hold up in dispute proceedings — knowing this gives you negotiating room.
- Renewal fees to the agency (更新事務手数料): Some agencies charge a renewal fee of 0.5-1x month's rent every two years at contract renewal. This is separate from the guarantor's annual renewal fee and is neither universal nor legally required. Some agencies waive it on request.
- No-subletting clauses: Standard and non-negotiable. Do not try to Airbnb your apartment — the penalties are severe.
Bottom Line
Finding an apartment in Japan as a foreigner without a Japanese guarantor is a solved problem in 2026. Guarantor companies — GTN and LEONET being the most foreigner-accessible — handle what a personal guarantor used to, and working with foreign-friendly agencies filters out the landlords who would have rejected you regardless. The real challenge is the upfront cash requirement: 4-6 months' rent is a significant sum, and arriving with that capital assembled, along with your passport, zairyu card, employment documentation, and income proof, puts you in a strong position. Chiba's suburban market makes the process somewhat easier than Tokyo, with higher acceptance rates and more zero-key-money inventory across the board.
