KDDI will expand the lineup of the online version of the data-only eSIM offered to international visitors to Japan, from March 25, 2026, based on customer usage trends. Two new plans designed for longer stays will be introduced: “Unlimited Data - 5 Days”* and “Unlimited Data - 7 Days”*.
In addition, the service will be provided in the format of a promotion code, with the starting date set by choice of the customers, enabling data usage to start at the timing needed during their stay in Japan.
With Japan SIM, customers can apply online for a data connection from overseas and download the built-in eSIM (embedded SIM) profile to their device in advance of their visit to Japan, allowing them to seamlessly use povo2.0 connectivity immediately after arriving in Japan.
Through providing Japan SIM, KDDI will continue supporting visitors to Japan to enjoy a comfortable and fulfilling stay.
