Upsell Technologies Inc. (Headquarters: Toshima-ku, Tokyo; CEO & Group Chairman: Ryota Takahashi / CFO: Masaki Ehara) announces that its AI operator "miraio," co-developed and operated with pluszero Inc. (Headquarters: Setagaya-ku, Tokyo; Chairman & CEO: Yoshiyuki Koshiro / President & COO: Ryota Mori), will be launched at two "Kakurean Shinobuya" restaurants operated by Horii Food Service Co., Ltd. (Headquarters: Mito, Ibaraki; President: Akihisa Fujita) starting Monday, May 18, 2026. This initiative aims to streamline reservation processes for restaurants, promote AI in store operations, address labor shortages, and enhance user convenience. ■ Introduction to "Kakurean Shinobuya" "Kakurean Shinobuya" is a restaurant brand known for its private "Wa" (Japanese-style) spaces with all private rooms. As part of the brand's operational DX, the "miraio" AI operator has been introduced. This allows store staff to reduce interruptions from phone calls and focus more on providing detailed hospitality to customers. ■ Implementation Details - Brand: "Kakurean Shinobuya" - Stores: Warabi Station East Exit store, Yashio Station Front store - Start Date: From Monday, May 18, 2026 ■ Background and Benefits To address severe labor shortages in the food service industry, "miraio for restaurants" offers a solution. It provides 24/7 automated responses for reservations, changes, and cancellations, preventing lost opportunities. By leveraging pluszero's patented "AEI" technology to suppress hallucinations, it ensures accurate and reliable responses. This reduces staff burden and allows them to focus on in-person customer service. ■ Features and Future Outlook The "miraio" AI operator can handle reservation changes/cancellations, automatically check and respond to availability based on date and number of people, and flexibly handle conversations that deviate from the standard script. We will continue to strongly support the sequential expansion of implementation across Horii Food Servi
