Tsuji-Hongo IT Consulting Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, President & CEO: Ken Kuronita, hereinafter "ITC") has launched the "AI Utilization Project (TH-AI)," a business transformation project for the entire Tsuji-Hongo Group, including Tsuji-Hongo Tax Accounting Firm (Headquarters: Shinjuku-ku, Tokyo, Chairperson: Saeko Kuwaki, hereinafter "TH").
Through this project, ITC will build a next-generation operational foundation centered on generative AI, promoting efficiency and quality improvement in tax accounting operations.
■ Project Overview
The accounting and tax industry faces severe labor shortages while demanding high levels of expertise and accuracy. The following points have been significant obstacles to business reform:
- Individualization and black-boxing of knowledge: Concentration of specialized knowledge in specific personnel.
- Burden of auxiliary tasks: Pressure on working hours due to auxiliary tasks such as meeting minute creation, document transcription, and content organization.
- Technical challenges in AI utilization: Issues during generative AI utilization, such as reading complex paper documents and information inaccuracies (hallucinations).
To solve these challenges, ITC, in collaboration with TH, launched this project with the aim of building an integrated AI platform that simultaneously achieves on-site business improvement and overall company optimization. By matching on-site needs with the latest generative AI technology, we will proceed with verifying business improvement effects such as:
- Efficiency through automation: Automating routine document creation and information organization with AI, reducing staff workload.
- Improvement in declaration operations quality: Utilizing AI in declaration-related operations that require expertise and accuracy, building an environment that efficiently and effectively utilizes necessary information while suppressing variations in knowledge and judgment.
- Resolution of "black box" by building a data analysis platform: Developing a platform to accumulate and analyze daily business flows as data. AI will automatically extract bottlenecks, accelerating continuous business improvement (PDCA).
■ Future Outlook
The "Next-Generation Accounting Firm Model where AI and Specialists Coexist" achieved through this project is considered to have social significance beyond the Tsuji-Hongo Group from the following perspectives:
- Improvement of productivity and value provided to customers across the entire tax and accounting industry: By integrating the knowledge cultivated as the industry leader with AI, "manual work" that remains deeply rooted in the tax and accounting industry will be transformed into "value as a specialist." By having AI handle routine tasks, professionals can maximize the time they spend as "partners for management," thereby improving the value provided by accounting firms.
- Transformation of management and back-office operations for small and medium-sized enterprises (SMEs): Deploying Tsuji-Hongo's specialized knowledge and operational flow "templates" to the back offices of SMEs facing resource shortages. Promoting advanced management visualization and rapid decision-making, thereby supporting the autonomous growth of SMEs, which are the backbone of the Japanese economy, from the back office.
ITC aims to support the business transformation of the Tsuji-Hongo Group and establish an advanced model for generative AI utilization in the tax and accounting industry by connecting the insights gained through this project to the implementation and adoption phases.
