Gourmet Review Platform 'Retty' and Office Building Media 'GRAND' Partner to Launch Location-Based Gourmet Content in Major Business Districts

Retty, Inc. (Headquarters: Minato-ku, Tokyo; CEO: Masaya Hirano), operator of Retty—a real-name review-based gourmet information and reservation platform—announces a content partnership with GRAND, Inc. (Headquarters: Shinjuku-ku, Tokyo; President & CEO: Hitoshi Sakagami), operator of the office building media network 'GRAND'. Starting in May 2026, location-specific gourmet video content has been rolled out across major office districts in Tokyo, Yokohama, Kawasaki, Nagoya, and Osaka. The full-scale multi-region rollout is now underway, delivering Retty’s curated gourmet information via GRAND’s network to business professionals across 28,000 tenant companies, tailored to their immediate office locations.

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

GRAND’s office building media network enhances the viewing experience for business professionals by programming dedicated content slots alongside traditional advertising on elevator digital signage.

Through this collaboration with Retty, GRAND enables the delivery of relevant, everyday dining information—directly tied to 'lunch,' 'business meals,' and 'after-work gatherings'—within office environments.
