ARCRA Inc. is a software development company with strengths in image recognition, natural language processing, agent AI, and AI implementation consulting. Since last fiscal year, the company has been selected for Ehime Prefecture’s public proposal program, Triangle Ehime 2.0, and has been working to promote digital transformation in the regional industry of pearl quality assessment. Building on last year’s successful work in judging six quality criteria, this fiscal year ARCRA will promote the development and social implementation of an initial commercial version designed to reduce pearl rough sorting time by 50% through real-world operation at four businesses in Ehime Prefecture. Triangle Ehime received approximately 1,500 applications nationwide over the four years from fiscal 2022 to fiscal 2025. Following the screening of fiscal 2026 continuing projects, 16 projects, including ARCRA’s, were selected. Development Background: The Technology Transfer Barrier Facing Traditional Industries Ehime Prefecture’s pearl industry boasts one of Japan’s highest production volumes, but it faces a shortage of successors and an aging workforce of skilled artisans. Pearl quality assessment, including luster, nacre thickness, and color, depends on tacit knowledge built through many years of experience. Training a fully skilled artisan requires a significant amount of time. ARCRA is quantifying this “artisan’s eye” through AI image analysis technology. By digitizing evaluation standards that had depended on individual expertise, the company aims not only to support skill transfer, but also to reduce the burden on production sites and strengthen the competitiveness of the entire production region. Three Key Points of This Fiscal Year’s Project First, the system will evolve into AI that can be used on-site. Following the success of last year’s verification, the system will be introduced at four local businesses engaged in actual pearl farming and processing. ARCRA will optimize every
