Japan- renowned for its advanced technology and efficient systems– often surprises foreigners with unexpected bureaucratic hurdles; one of which is obtaining a mobile number! 

While mobile phones are ubiquitous in Japan, the process of acquiring a mobile number can be challenging for non-residents and even locals under certain circumstances. Adding to the complexity, a Japanese mobile number is often necessary to submit applications for essential services, such as renting an apartment 

Here’s a detailed look at why this process is so complex: 

 

1) Stringent Identification Requirements

Japan has strict laws regarding identity verification for financial services, as well as mobile contracts. This stems from the country’s efforts to curb illegal activities such as fraud, money laundering, and terrorism.  

To get a mobile number, you typically need: 

  • A valid Residence Card or a visa showing a sufficient length of stay. 
  • A Japanese bank account or credit card for billing purposes. 
  • Proof of address, such as a utility bill. 

For short-term visitors, who usually lack a Residence Card, obtaining a regular mobile number is nearly impossible. Instead, they are often limited to prepaid SIM cards or rental services. 

 

2) Language Barrier

While Japan has made strides in offering multilingual services in recent years, many mobile carriers primarily operate in Japanese. The application process, contracts, and customer support are often only available in Japanese. For those who don’t speak Japanese, this can make it difficult to navigate the system without assistance. 

 

3) Complex Contract Terms

Mobile phone contracts in Japan are notoriously intricate, with lengthy documents detailing terms, fees, and penalties. These contracts often include: 

  • Cancellation fees for early termination. 
  • Specific clauses for device financing. 
  • Requirements for a long-term commitment (usually two years). 

Understanding these terms is essential, but it sure can be daunting for anyone unfamiliar with Japanese contract norms. 

 

4) Limited Options for Foreigners

For short-term residents, options are limited to prepaid SIM cards, which often come with restrictions such as: 

  • No ability to make international calls. 
  • Limited data plans. 
  • No access to a Japanese phone number for SMS verification. 

While these prepaid options are convenient, they don’t offer the full functionality of a standard mobile plan, making them less suitable for long-term use.
