Overview
What it does: YAYOI runs a global chain of teishoku Japanese restaurants that offer traditional set meals served on a single tray. How the product works: Meals follow ichiju-sansai (one soup, three sides); in Japan customers often use ticketing for orders, while abroad they use table-side tablets to order, track progress, and pay, with fresh meals served together on a tray. How it differs from competitors: It combines a long history dating back to 1886 with adaptable dining formats and technology-enabled self-ordering, across 300+ outlets worldwide. Its goal: Make nutritionally balanced teishoku meals widely available through a scalable, authentic dining model with convenient, tech-assisted service.
