A New Era of Connectivity for Australian Japan-Bound Tourists

Melbourne, AUSTRALIA – November 07, 2025– RYSfly, a leading provider of digital travel connectivity solutions, today announced the launch of its Premium Japan eSIM service for Australian travelers, establishing a strategic partnership with KDDI, one of Japan’s premier telecommunications operators, utilizing the highly-rated au network.

The new offering is specifically designed to provide Australian tourists, business travelers, and digital nomads with a seamless, high-speed, and cost-effective mobile data experience from the moment they land in Japan, eliminating the hassle of traditional roaming or physical SIM card purchase.

Australian travelers to Japan can now enjoy direct access to the au network, known for its 5G coverage, delivering fast and reliable internet across major Japanese cities like Tokyo, Kyoto, and Osaka, as well as rural and regional areas.

It provides the quality and speed of a local Japanese SIM, combined with the simplicity and convenience of eSIM technology that Australian travelers expect.”
