Labour shortages are the number one issue that needs to be address, Lawson President Sadanobu Takemasu said at a news conference on Wednesday. "We aim for stores with the highest growth potential in the world," he added. KDDI will provide technical support for the project while leveraging Lawson's stores to expand its customer base. It will also renew its subscription services next month to distribute coupons that can be used at Lawson stores.
