For those seeking English-language assistance during setup or usage, multilingual interfaces and customer interaction are provided through selected carriers.
What SIM Options Are Available for 5G in Japan?
Japan’s major carriers provide both physical SIM cards and eSIM solutions for 5G connectivity. Physical SIM cards remain widely available through carriers like NTT Docomo, au by KDDI, and SoftBank. eSIM technology is gaining traction, allowing users to activate service digitally without a physical card. Both options support full 5G capabilities across compatible devices and offer various data allowances.
How Does eSIM Compatibility Work with Japanese Networks?
Japanese carriers have embraced eSIM technology, making it easier for users with compatible devices to connect to 5G networks.

Can Unlocked Phones Access Japanese 5G Networks?
Most unlocked 5G phones can connect to Japanese networks, provided they support the appropriate frequency bands. However, users should verify their device’s compatibility with specific carriers, as some phones may require band support for n77, n78, or n257 frequencies commonly used in Japan. Additionally, phones must be officially certified for use in Japan through technical compliance certification.
