How our guarantee service works
We examine your application for the guarantee service.
Please make the necessary arrangements with a real estate company in advance.
1. Application for guarantee
[Tenant → Real estate company]
Contact a real estate company that handles Nihon Safety’s guarantee system. Please submit the specified application and necessary documents.
* Remember: The documents you submit will not be returned.
2. Acceptance and examination
[Real estate company → Nihon Safety]
We review the contents of your application, confirm details, and decide whether to provide the guarantee.
3. Notice of examination results
[Nihon Safety → Real estate company → Tenant]
After we examine the application, the real estate company will notify the tenant of the results of our decision.
*Your application may be rejected on the basis of the information it contains.
4. Contract
[Real estate management company ←→ Tenant]
When your application is accepted, you will be asked to enter a guarantee consignment contract. Sign and seal the contract, and pay the guarantee charge*1.
The guarantee period is two years*2. If you continue renting over a long term, the guarantee period will have to be renewed every two years. You will have to pay a safety fee for each renewal.
