Launch of New Service "Mirror Advertising" Actual "Mirror Advertising" installed at Myoho-yu (Toshima-ku) Our company has newly started handling "Mirror Advertising," an offline advertising service that utilizes the mirror space in bathrooms, in addition to our "Furo Vision" digital signage for hot bath facilities. Mirror Advertising is a traditional advertising method that displays advertisements around the mirrors in the washing areas of public baths and hot bath facilities. It can be used as an advertising medium that naturally catches the eye during washing and shampooing. Conventional mirror advertising involved embedding advertisements directly into the mirrors themselves, which presented inconveniences such as differing specifications for each facility, the need for construction, and limited replacement periods. Our "Mirror Advertising" has been updated to unify specifications for each facility (297mm x 100mm) by attaching acrylic plates to existing mirrors, making it possible to easily change advertising content. This allows hot bath facilities to utilize their bathroom space as a new revenue opportunity without significant capital investment or operational burden. For advertisers, it enables more local advertising, delivering information naturally to residents within the来店圏 (customer reach area). Please refer below for a list of participating facilities. List of Participating Facilities 3 months, 6 months, 12 months 1 sheet (male or female bath only): 7,500 yen/month (excl. tax) Male and female set (1 sheet each): 10,000 yen/month (excl. tax) *Separately, an acrylic plate production fee of 10,000 yen (excl. tax) is required per sheet. *If displayed for 12 months, a discount equivalent to 2 months' display fee will be applied.
