In the real estate and human resources service sectors, labor shortages, task individualization, and increased burden of document creation and aggregation are progressing, making on-site business improvement a management challenge.
Meanwhile, while corporate utilization of generative AI is expanding, mainly in auxiliary areas such as email, meeting minutes, and document creation, the challenge remains that "we don't know how to apply it to our department's operations."
Comix Inc. (Headquarters: Maruyama-cho, Shibuya-ku, Tokyo; Representative Director: Akihiro Suzuki) is continuously providing customized generative AI utilization support for five departments—General Affairs, Recruitment, Sales, Finance, and Education—to a client company operating in real estate and human resources services, ongoing for 10 months.
■ Background and Challenges
According to the Ministry of Internal Affairs and Communications' "2025 Information and Communications White Paper," the percentage of Japanese companies using generative AI for some kind of work is 55.2%, and the percentage using it for auxiliary tasks such as email, meeting minutes, and document creation is 47.3%. On the other hand, the most common concern during introduction is "not knowing how to effectively utilize it," and generative AI is transitioning from the recognition and trial stage to the practical implementation stage.
Even at the client company being supported this time, each department faced challenges such as "I'm interested in AI, but I don't know how to apply it to my work" and "Company-wide uniform training doesn't lead to daily business improvements." Therefore, the company introduced Comix's "Generative AI Utilization Support" as hands-on assistance to design utilization themes according to departmental business challenges and integrate them into practical operations.
■ Services Provided
1) Department-specific one-on-one generative AI utilization support
Comix's generative AI utilization support is not general group training; instead, CIO Go Hashimoto conducts one-on-one online interviews with each person in charge to design and implement utilization methods tailored to each individual's business challenges.
In the support, based on a business challenge questionnaire for the target individuals, the type of work, working hours, and degree of individualization are organized. Then, AI experts select utilization themes, and in individual interviews, they concretize prompts, business flows, and points of caution during operation. Furthermore, monthly regular reports are made to the management, establishing a system to connect on-site initiatives to management decisions.
2) Continuous hands-on support for 10 months for 8 people in 5 departments
This support has been ongoing from the initial kickoff in July 2025 to April 2026, with a total of 34 online interviews conducted for 8 people across 5 departments. The focus is not merely on explaining how to use it, but on integrating generative AI into the practical work of each person in charge.
■ Main utilization themes in 5 departments
In the General Affairs Department, efforts are being made to support account management, loaner item management, anomaly detection of attendance data, internal FAQs, and creation of internal system operation guides. The main themes are streamlining application processing concentrated at the beginning and end of the month, and inquiry response.
In the Recruitment Department, support is provided for creating job postings and scout messages for different media, creating meeting minutes for recruitment interviews, creating handover documents for the next selection stage, measuring the effectiveness of recruitment data, and creating SNS and public relations content. Emphasis is placed on creating texts tailored to multiple media and standardizing information sharing after interviews.
In the Sales Department, progress is being made in creating negotiation materials and proposals, analyzing sales performance, market research, and competitor analysis. In the Finance Department, efforts include creating B/S and P/L reports, fund forecasting, AI proposals for journal entries, and multilingual communication support. In the Education Department, progress is being made in creating training content, preparation materials for interviews, considering AI for PowerPoint proofreading, and designing a company-wide AI literacy improvement program.

■ Features and Strengths
- Design that breaks down operations by department: According to the business characteristics of General Affairs, Recruitment, Sales, Finance, and Education, efforts are prioritized from tasks where reduction effects are easily achieved.
- Direct hands-on support by CIO: Beyond just introducing AI tools, practical flows, prompts, and operational rules are individually designed.
- Monthly reporting to management: Visualizes the on-site utilization status, preventing it from ending in individual trial and error, and transforming it into decision-making material for company-wide deployment.
- On-site introduction of the latest tools: In April 2026, hands-on support was provided for about 60 minutes, from setting up Claude Code to authenticating the Google Apps Script integration tool "Clasp."
■ Estimated Effects
This support estimates that work hours can be reduced by 80-95% for meeting minute creation, 65-70% for data analysis and aggregation, 70% for job posting and scout message creation, 75% for inquiry response, 60% for financial report creation, and 40-55% for sales material creation, based on business challenge questionnaires and interviews with each department.
These are estimated values based on Comix's AI utilization questionnaire analysis, and moving forward, reduction times and utilization frequency will be based on actual operational data.
