Best guarantor companies for foreigners in Japan (2026): cost, screening, and language support compared
Compare major guarantor companies like GTN, Four Leaf, and Japan Safety by cost, approval rate, and multilingual support to find the best fit for foreign applicants.
Guide
1. What is a guarantor company and why do foreigners need one?
Japanese rental contracts typically require a guarantor (rentai hoshounin). Since most foreigners lack a Japanese guarantor, guarantor companies fill this gap. Initial fees range from 50% to 100% of monthly rent. With a valid residence status and stable income, most foreign residents can qualify.
2. Comparison of major guarantor companies
GTN specializes in foreign residents with 16-language support; initial fee from 50% of rent. Four Leaf accepts a wide range of visa types including technical interns. Japan Safety offers fast screening with same-day approval possible at 50%+ initial fee. JID provides monitoring services alongside rent guarantee. Casa has strong management company partnerships with high property coverage. Fees, annual renewals (around ¥10,000), and required documents vary by company.
3. Tips to improve your screening approval chances
To improve approval odds: (1) prepare residence card, passport, and 3 months of payslips or offer letter without gaps; (2) secure an emergency contact in Japan; (3) choose properties where rent is under one-third of monthly income; (4) keep inquiry and application details consistent. If you have credit card delinquency history, avoid credit-based guarantors and choose independent ones like GTN.
4. Checklist for choosing a guarantor company
When comparing properties, also check the guarantor company details: initial fee percentage, annual renewal cost, supported languages, required documents, screening timeline, and accepted visa types. Use Bridge Home Japan's guarantor-company theme search to find listings with clear guarantor company information.
Frequently asked questions
What should I do if a guarantor company rejects my application?
Rejection by one company does not mean all will reject you. Try switching from credit-based to independent guarantors like GTN, adding income proof, or changing your emergency contact. Ask your real estate agent for alternative guarantor company suggestions.
Do I pay guarantor fees every year?
Most guarantor companies charge an annual renewal fee (around ¥10,000) in addition to the initial fee. Some companies waive renewal fees, so confirm before signing.
Can technical interns use guarantor companies?
Yes, companies like Four Leaf and GTN accept technical interns. However, you may need cooperation documents from your supervising organization, so check in advance.
