AI Perfectly Replicates Professional Hygiene Management Honed at Kameda Medical Center: AI Cleaning Shift Management App "SOZY," Which Analyzes Dirt from Site Photos to Optimize Staffing, to Launch on May 19, 2026

Busy Bee Inc. (HQ: Tokyo, hereinafter "our company") and Prana Inc. (CEO: Tadao Matsumoto) have systematized the advanced hygiene management methods Mr. Matsumoto cultivated in the environmental services department of Kameda Medical Center. They have co-developed the AI hygiene management and cleaning shift optimization platform "SOZY" (https://sozy.info/), which will be available starting Tuesday, May 19, 2026. ■ Background: Digitizing the "Intuition and Experience" of the Cleaning Industry to Address Labor Shortages The cleaning and hygiene management industry faces significant challenges, including severe labor shortages and a reliance on the knowledge of veteran staff, leading to a "personalization of skills." Our company has developed a solution that allows anyone to achieve expert-level hygiene management by having AI learn the expertise of Mr. Tadao Matsumoto, a leading figure in hospital cleaning in Japan from Kameda Medical Center and a consultant for numerous medical institutions. Professional techniques honed at Kameda Medical Center, reproduced by AI. ■ Three Innovative Features of "SOZY" 1. AI Dirt Cause Analysis Engine Simply by taking a photo of the site, the AI instantly identifies the type of dirt, its cause, and the optimal removal method. It provides precise instructions based on Mr. Matsumoto's 40 years of professional know-how. 2. Weekly Hygiene Analysis Report It analyzes trends in dirt occurrence on a weekly basis from accumulated image data, enabling a shift from reactive cleaning to data-driven "preventive cleaning." 3. Intelligent Shift Allocation Based on the analyzed dirt load status, it automatically assigns staff with the optimal skills to the appropriate locations, maximizing on-site operational efficiency. ■ Implementation Record and Future Development Implementation has already been decided for Kameda Medical Center, which boasts one of Japan's highest medical standards. It will be sequentially rolled out to large-scale medical institutions such as national and prefectural hospitals where Mr. Matsumoto consults. Furthermore, by applying the high-precision analysis logic cultivated in medical settings, we will accelerate expansion into a wide range of building maintenance areas, including office buildings and rental housing. We have already received many inquiries from major companies in various industries and plan to proceed with proof-of-concept experiments and implementations sequentially. ■ Co-developer: Mr. Tadao Matsumoto Profile Mr. Tadao Matsumoto, Manager of Environmental Services Dept. at Kameda Medical Center / CEO of Prana Inc.
