When preparing to study in Japan at a university, language school, or specialized training college (vocational school), international students encounter two distinct guarantor requirements: a financial guarantor for the visa application and a housing guarantor or rental guarantor company when signing an apartment lease. To obtain a Certificate of Eligibility (COE) for a student visa, applicants must prove financial viability of at least 3,500,000 yen, which can be backed by a sponsor such as a parent. For private housing, options include institutional schemes like JEES Comprehensive Renters' Insurance or commercial rental guarantor companies. Always confirm specific requirements with official university and government sources.
What is a financial guarantor for a Japanese student visa?
To obtain a student visa to enter Japan, foreign nationals residing outside the country must first obtain a Certificate of Eligibility (COE) issued by the Japanese Immigration Bureau (TUJ Visa Guide). As part of this application, students are required to demonstrate proof of financial viability totaling 3,500,000 yen or more (or the equivalent in foreign currency).
Financial documents must be dated within the last three months and show the actual source of the funds. Acceptable proof includes:
- Bank statements
- Scholarship award letters
- Retirement account statements showing cash or loan availability
- U.S. financial aid award letters or loan approvals
- GI Bill Certificate of Eligibility
If a student cannot show the required 3,500,000 yen under their own name, a financial guarantor—such as a parent or relative—can submit financial proof on their behalf along with a signed Letter of Sponsorship.
Along with financial proof, applicants must upload a headshot photo taken within the last three months (4 cm high by 3 cm wide, or 2 inches by 2 inches, with a plain white or off-white background) and clear passport copies. Passport holders from the Philippines, Nepal, and Viet Nam must also complete the Japan Pre-Entry Tuberculosis Screening (JPETS) at a designated panel clinic and submit a TB Clearance Certificate by the COE application deadline.
What is the COE timeline and visa processing routine?
Planning around the official immigration timeline helps ensure a smooth arrival:
- COE Application & Processing: The educational institution submits the COE application to the Immigration Bureau on the student's behalf. Issuance generally takes 6 to 8 weeks. Since March 17, 2023, the Immigration Bureau issues COEs via email, allowing applicants to present a printed copy or digital email when applying for their visa or entering Japan (MOFA Visa FAQ).
- Embassy Visa Application: After receiving the COE, the applicant submits their visa application to the Japanese Embassy or Consulate in their home country or country of residence. Standard processing takes 5 working days from the day after acceptance.
- Visa Validity and Arrival: A single-entry student visa is valid for 3 months from its issue date. Students may enter Japan up to 21 days before the first day of classes, and a residence card is issued upon arrival at the airport.
- Reapplication Restrictions: If a visa application is rejected, consulates will not accept a new application for the same purpose within 6 months unless personal circumstances change significantly or humanitarian reasons apply.
How does the housing guarantor system work in Japan?
Many newcomers stay in a furnished monthly apartment first while organizing their long-term living arrangements. When securing a standard private apartment lease in Japan, landlords usually require a joint surety (guarantor) to cover unpaid rent or property damage. International students without family in Japan can utilize student-focused guarantor systems (Tohoku University Guarantor System).
Commercial Rental Guarantor Companies
Real estate agencies frequently connect international tenants with commercial rental guarantor companies. These companies charge a guarantee fee typically ranging from 50% to 100% of the monthly rent upon signing the initial contract, with a recurring fee due upon contract renewal.
JEES Comprehensive Renters' Insurance (Ryuhosho)
International students enrolled in eligible institutions—including universities, junior colleges, technical colleges, special courses at professional training colleges, and approved Japanese language schools—can utilize the Comprehensive Renters' Insurance for Foreign Students Studying in Japan (Ryuhosho) (JEES Comprehensive Renters' Insurance).
- Joint Surety Role: Under Ryuhosho, the student's school, a faculty member (such as the director of the International Student Center), or a local international exchange association acts as the joint surety. The school must participate as a partner school, which requires a ¥50,000 registration fee.
- Guarantor Protection: The system operates a Guarantors' Protection Fund that reimburses the joint surety up to ¥300,000 for unpaid rent (up to 3 months) or restoration costs (up to ¥100,000) if the lease is canceled and the accommodation is surrendered.
- Insurance Coverage: Includes tenant liability insurance up to ¥50 million per accident for damage caused by fire, explosion, or water leakage to lower floors, plus up to ¥2.4 million for disability resulting from an accident.
- Fee Structure: Premiums and fund contributions cost ¥4,000 for 1 year (¥2,500 insurance + ¥1,500 fund), ¥8,000 for 2 years, or ¥2,000 for a 6-month extension.
Some institutional support plans, such as the Sumuraku Plan introduced in January 2025, offer 24/7 multilingual emergency call centers and require specialized coverage like Inbound Futai Gakuso (10,000,000 yen tenant liability). If a student moves out or terminates their housing guarantor plan with more than 1 month of remaining coverage, a partial premium refund can be requested, which takes 1 to 2 months to process into a Japanese bank account.
Finding a place to stay
Arranging housing requires careful timing during your transition to Japan. While waiting for your COE and visa processing—which takes between 6 to 8 weeks for the COE plus 5 working days for the visa—it is wise to research accommodation options. After your visa is confirmed, you should secure temporary lodging before arriving in Japan. OHAYO Stay offers furnished monthly apartments and rooms in Tokyo; most homes have a minimum stay of 30 nights (shown on each listing). No guarantor, no key money and no agency fee; booking is online with a passport or ID and a credit card. The monthly price includes electricity, gas, water and Wi-Fi. Having guaranteed housing ready upon arrival lets you settle in smoothly before classes begin.
