GRAND Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President & CEO: Hitoshi Sakagami / Mitsubishi Jisho Group), operator of the office building media platform 'GRAND', has launched a content partnership with Retty Inc. (Headquarters: Minato-ku, Tokyo; CEO: Masaya Hirano), operator of the real-name review-based gourmet information and reservation site 'Retty'. Starting in May 2026, area-specific gourmet content will be rolled out across major office districts in Tokyo, Yokohama, Kawasaki, Nagoya, and Osaka. The initiative will deliver localized gourmet information tailored to the office locations, enhancing the viewing experience on elevator digital signage for business professionals across 28,000 reachable tenant companies.

Background of the Partnership — Strengthening the 'Content Slot' Alongside Advertising

The office building media platform 'GRAND' has continuously enhanced the quality of viewing experiences for business professionals by curating dedicated content slots on elevator digital signage.

Through this collaboration with Retty, a real-name review-based gourmet information and reservation site, GRAND will now deliver dining content directly tied to business professionals’ everyday interests — such as 'lunch,' 'business dining,' and 'after-work gatherings' — within office environments. Daily practical information fosters habitual viewing, thereby improving media quality and increasing advertising value for advertisers.

Comment from Retty Representative

We are delighted that Retty’s area-specific gourmet information can now reach the many business professionals who pass through office buildings every day. We believe this partnership will naturally deliver highly trustworthy information — based on real-name reviews — at the very moment users are deciding where to eat for lunch or business dinners.

Comment from GRAND Representative

We have always aimed to deliver useful information during the time people spend in elevators. By integrating Retty’s area-specific gourmet videos into our content slots, we will now provide nearby, practical, and relevant dining suggestions right where users need them.

Value for Advertisers — Creative Excellence on a 'Watched Media'

Adding gourmet content to office building media creates practical daily value for viewers. The expected benefits include:

- Increased Exposure Frequency: Practical daily information fosters habitual viewing, transforming the screen into a 'watched media' - Improved Favorability & Recall: Enhanced recognition and positive sentiment toward ad creatives shown alongside content - Sustained Media Value: Strengthened credibility and trust in the media through enriched utility content
