The guarantor office is currently accepting applications by post (online application beforehand) . However, you can consult us in person at our office if you are in a hurry. Please contact us by Email in advance if you would like to visit the office in person.
Almost all apartment leases in Japan require a guarantor (rentai hoshonin), a person who co-signs the lease to share liability (jointly and severally) with the tenant for any debts to the lessor. Generally, Japanese students ask a family member (parent, sibling, etc.) to serve in this role, but since international students often do not have someone who they can ask to be a guarantor, the University of Tokyo may act as your guarantor if you meet certain eligibility requirements.
【Regarding the renewal of your lease contract】You need to reapply for the University Guarantor System again when you renew the lease contract. Please note that your guarantee is NOT automatically updated.
Applications take around 7 days to process.
Apply at least two weeks before your planned move-in date.
■ Eligibility Requirements
(1) Must Enroll at the University of Tokyo as an undergraduate, graduate or research student; also prospective students to enroll into the University of Tokyo who require the guarantor service in order to commute to campus before school starts.
