Different Types of SIM Cards and eSIMs Available

Prepaid SIM Cards

These SIM cards offer a fixed amount of data and a predetermined duration, making them an excellent choice for tourists. They provide flexibility and cater to both data-only and voice/data usage preferences.

Long-Term SIM Cards

If you’re planning an extended visit to Japan, long-term SIM cards with monthly plans can offer cost-effective solutions. Some of these plans provide unlimited data and calls within Japan for a fixed monthly fee.

For travelers planning to explore both Japan and other countries, you’ll find SIM cards and eSIMs designed for international use. These versatile options ensure you stay connected not only within Japan but also during your travels abroad.

Coverage and Data Options

  • Network Coverage: While Japan enjoys excellent network coverage, it’s essential to identify the mobile network(s) your selected SIM card or eSIM operates on. Major carriers include NTT Docomo, SoftBank, and KDDI au. Research the coverage and reliability of the carrier to ensure a strong signal in your desired locations, whether you’re in urban areas or rural regions.
