Many business people stay in Japan for extended periods due to projects or business trips. Additionally, there is a growing number of students who come for short-term studies to learn Japanese or participate in cultural exchange programs. Recently, due to the influence of digital nomad visas, more people are staying in Japan for over a month. However, for such people, the SIM cards or eSIMs available at Japanese airports often fall short in terms of usage period and data capacity. Many end up buying multiple SIM cards or replacing their eSIMs each time they run out of data to ensure uninterrupted communication during their stay. That can be a bit of a hassle, right? Given the increase in people staying for about three months, dedicated eSIMs and SIM cards are now available.
In Japan, the sale of SIM cards or eSIMs with local phone numbers is restricted to residents. This is due to stringent security requirements. However, anyone can purchase data-only eSIMs and SIM cards. If you wish to make calls during your stay in Japan, consider using communication apps like Skype or obtaining an IP phone number.
When considering the best SIM card or eSIM plan for those staying in Japan for about three months, the key is a plan that allows for smooth communication in Japan with just a one-time setup.
To achieve this, the following are essential:
The SIM cards and eSIMs sold at airports are often designed for usage periods of about 30 days, making them unsuitable for those planning to stay longer in Japan. However, data-only SIM cards and eSIMs that can be used for over 90 days are also available. The plans introduced below are products we offer, prepared in response to inquiries from those needing a SIM card or eSIM plan for a roughly three-month stay. They are widely used by business travelers and short-term students.
Services offering SIM cards or eSIMs for periods exceeding 30 days are mostly available through online shops. Please refer to the products introduced here to find a plan that suits your needs.
