LINE is a messaging service that has approximately 83 million active users a month in Japan and is widely used by a wide range of age groups. By using LINE to deliver the contents of the “Notice of Electricity Charges” which is mailed by postcard every month, customer’s convenience will improve, and a monthly 50 yen discount will be applied to customer’s charge.
