Ways to connect to wifi in Japan

Use free wifi

Free wifi in Japan is very popular and easy to find. Shopping malls such as AEON, Don Quijote, or convenience stores such as 7-Eleven, Lawson all provide free wifi service to customers. However, this type of connection often has a limited time of use and unstable speed, especially during peak hours.

Use wifi transmitter

Pocket WiFi is a popular choice for tourists and foreigners in Japan. These devices allow high-speed internet connection to multiple devices at once. Pocket WiFi from carriers such as SoftBank, au, or Docomo offers stable speeds and wide coverage across the country.
