Why Is a Mobile Phone Number Necessary for Rental Contracts in Japan?
When applying for a rental contract in Japan, having a Japanese mobile phone number is often a mandatory requirement. For those residing in Japan, obtaining a mobile number is usually straightforward, and most people already have one. However, for individuals living outside Japan or those with foreign citizenship, the lack of a Japanese mobile phone number can pose significant challenges in securing a rental property.
In this article, we will explore why a Japanese mobile number is necessary, the situations where it’s required, and how to address this need if you don’t currently have one.
Why Is a Mobile Number Important?
A mobile phone number is a required field on rental application forms in Japan. Here’s why it holds such importance:
- Identity Verification During Screening Before proceeding with a rental contract, applicants go through a screening process involving rent guarantee companies or credit card companies. As part of this process, a mobile phone number is essential for direct communication to verify the applicant’s identity.
- Communication With Property Management Property management companies or landlords need a reliable way to contact tenants for emergencies or other matters. Without a mobile phone number, applications may be rejected outright.
- Expanded Property Options Having a mobile phone number increases the range of properties available to you. For foreign nationals, the presence of a mobile number can be a decisive factor in whether certain properties accept their application.
When Else Is a Mobile Number Required?
Beyond the application process, a mobile phone number is also necessary in the following scenarios:
- Applying for Fire or Home Insurance
Many rental contracts require tenants to obtain insurance, and a mobile number is needed for this application. - Registering for 24-Hour Assistance Services
Services for security or equipment troubleshooting also require a mobile phone number for registration.
These examples show that a mobile number is more than just a contact detail—it’s an integral part of the rental process in Japan.
How to Obtain a Mobile Phone Number
If you need to acquire a Japanese mobile number, there are several ways to do so:
- Visit a Mobile Carrier Store
Major carriers like NTT Docomo, AU, and SoftBank, as well as budget SIM providers like Rakuten Mobile and UQ Mobile, offer services at physical stores. Bring the required documents, and you can often obtain a number on the same day. - Apply Online
Many providers now allow online applications, making the process faster and more convenient for busy individuals. - Use eSIM Services
An eSIM allows you to activate a mobile number without a physical SIM card. While not all eSIM services are available to overseas residents, it’s worth checking with compatible providers. - Purchase a Prepaid SIM
For short-term use, prepaid SIM cards available at convenience stores or airports can be a viable option. These require no pre-screening and are ready for immediate use.
