Being connected to the internet is of great importance in Japan, especially for foreigners. You can use it to navigate the sometimes confusing public transport system, translate unknown words, and simply stay connected with your friends and family. With these convenient SIM cards, you can immediately get an internet connection.  This SIM card has high-speed internet access (4G LTE) and no data limits. It is available for a duration of either 8, 16, or 31 days. It works on the Docomo network, Japan’s biggest network provider. The SIM card connection covers 99% of Japan. It can be adjusted to fit as a nano, micro, or normal SIM card.  If you wish to pick up the SIM at a post office in the airport, please make sure to pick it up during the open hours of the post office. For post office collection, the staff will confirm the name on your passport and then give you the parcel.
