TOKIUM Inc. (Headquarters: Chuo-ku, Tokyo; CEO: Kenichi Kurosaki; hereinafter 'TOKIUM'), provider of the Accounting AI Agent, announced that the first book by its CEO Kenichi Kurosaki, 'Accounting AI Agent: Work Runs Smoothly with a Digital Workforce' (CrossMedia Publishing), has been slated for a reprint.
This book secured the #1 spot in Amazon's Best Sellers ranking in both the Tax & Accounting and Industrial Research Reference/White Paper categories. It also claimed the #1 weekly ranking at Maruzen Marunouchi Main Store and Yurindo Atre Ebisu Store. Fueled by growing expectations for AI agents to combat the shrinking workforce, a reprint was decided just three weeks after launch.
## Book Overview
It is estimated that Japan will face a labor shortage equivalent to 3.84 million people by 2035 (Persol Research Institute and Chuo University, 'Future Estimate of the Labor Market 2035'). In response to this challenge, this book outlines a path to utilizing AI as an autonomously operating 'digital workforce'.
Based on the practical knowledge the author has accumulated over 13 years of automating accounting tasks, the book explains everything from designing AI implementations to organizational transformation. Additionally, it systematically unveils 'micro-task decomposition', a workflow design method cultivated by TOKIUM in its development field. This method of breaking down complex operations into minimal units to clearly separate tasks handled by AI from those managed by humans can be applied not only to accounting but to all back-office operations.
