He reportedly sent a message regarding his recommendation to all municipal government employees. The mayor is aiming to eliminate harassment and create open workplaces. Yokoyama asked civil workers to refer to him using "-san" instead of his title and commented, "When people refer to me using '-san', I don't feel bothered, and it makes it easier to speak."
