When first arriving in Japan, choosing major carriers like Softbank, au, or Docomo can present several challenges for foreign residents. These companies typically require a minimum visa period of 2 years and impose 2-year contract obligations. If you need to cancel your service before the 2-year period ends, you’ll face hefty cancellation fees. Additionally, monthly fees from these major carriers are extremely expensive.

On the other hand, by choosing budget SIM cards with no minimum contract periods, you can easily obtain mobile service at much more affordable rates, even if your visa is valid for less than 2 years.

This comprehensive guide introduces the best mobile carriers and value plans specifically designed for foreigners living in Japan, along with essential tips to increase your application approval chances.

Types of SIM Cards Available in Japan

Japan offers three main types of SIM cards: “Data Only,” “Data + SMS,” and “Data + Voice Calls.”

InternetSMSVoice Calls
Data + Voice Calls
Data + SMS
Data Only

Since phone numbers are required for most official procedures in Japan, we strongly recommend choosing “Data + Voice Calls” SIM cards that include internet, SMS, and voice calling capabilities. This guide focuses exclusively on “Data + Voice Calls” SIM card pricing plans.

Essential Tips to Increase SIM Card Application Approval

1- Choose Credit Card Payment

SIM card providers offer various payment methods including credit card payments, automatic bank transfers, and convenience store bill payments. Selecting credit card payment significantly increases your chances of SIM card application approval.

When you first arrive in Japan, the possibility of obtaining a credit card domestically is extremely low. Therefore, bringing a credit card issued in your home country will make life easier until you can obtain a Japanese credit card.

If you have a stable income and have been in Japan for more than 3 months, you can also apply for Rakuten’s credit card (Rakuten Card). International students with income from part-time jobs or scholarships are also eligible to apply, so please check it out.

2- Apply for SIM Card Only

Many Japanese carriers offer smartphone bundles with SIM cards, available for purchase through lump-sum or installment payments. However, newcomers to Japan attempting to purchase smartphones through installment plans may face reduced approval chances.

Using credit card installment payments has a slightly higher approval rate than bank transfers. However, if you want to obtain a SIM card with minimal hassle, we recommend either paying for smartphones upfront or applying for SIM cards only.

3- Hold a Visa Valid for 2+ Years

Your visa duration is a crucial factor in SIM card application approval. Some carriers don’t accept applications from individuals without visas valid for at least 2 years. The SIM card companies recommended in this guide generally don’t impose visa period restrictions.

Required Documents for SIM Card Applications

While requirements vary by carrier, you’ll typically need:

Required documents for SIM card applications
  • Residence Card (Zairyu Card)
  • Passport
  • Credit card, debit card, or bank cash card
  • Personal seal (Inkan)

JEC’s SIM Card Recommendations

When obtaining a SIM card from mobile carriers immediately upon arriving in Japan, you may face difficulties if your Japanese isn’t sufficient or due to visa period constraints (if you have a visa shorter than 1 year). Therefore, we recommend initially avoiding complex procedures and purchasing from SIM card companies like Sakura Mobile, even if slightly more expensive, to choose a suitable plan and start using services. You can receive SIM cards at the airport upon arrival, and payments can be made via credit card/debit card or Smart Pit card (cash payment at convenience stores).

After several months of getting accustomed to life in Japan and reaching a sufficient level of Japanese, you can apply online and obtain SIM cards from the budget SIM card companies introduced above.
