At the heart of this will be the expansion of KDDI's existing digital loyalty programme, au Smart-Pass Premium, which includes digital streaming entertainment and books, shopping coupons, partner discounts and other offers for a monthly fee of 548 yen ($3.67). (Note au is the brand used by KDDI for its consumer services.) For the green element, KDDI plans to contribute towards and enhance Lawson's existing "environmental vision", which includes the use of solar panels at stores and a reduction in the use of plastics to improve efficiencies and reduce the carbon footprint of the shop network. KDDI noted that it is "expanding into a wide range of business areas", such as "banking, insurance, education, travel, and delivery services", in addition to communications services. "Additionally, KDDI operates one of Japan's largest subscription services – au Smart-Pass Premium – with over 13 million users," it added.
