Hitachi AI Lifts Domestic IT Service Productivity 10%
Summary
Hitachi says AI improved domestic IT service productivity by 10%, expanding delivery capacity, but its revenue and profit impact remains unquantified.
Hitachi, Ltd. (HTHIF) said on its July 29, 2026 quarterly earnings call that AI improved productivity in domestic IT service delivery by 10%. The company has not disclosed the calculation method, the number of projects covered, or the revenue or profit attributable to the application.[1]
Hitachi provides digital systems and IT services to enterprise customers, generating revenue through system development, integration, and subsequent operations. Its domestic IT service teams use this AI application in customer-project development and delivery, particularly for labor-intensive coding and testing. People remain responsible for architecture, design, project management, and decisions about where AI is used. The application therefore affects core delivery capacity rather than a peripheral support function.[2]
From development tasks to delivery capacity
Hitachi's disclosures show the application's scope and business objective becoming clearer. On April 27, 2026, the company said AI was being used for coding and testing in domestic system-development projects and had produced an average 10% improvement in production efficiency. On July 29, 2026, Hitachi described the same application in the broader context of domestic IT service delivery and said the goal was to serve more customer demand with limited IT resources. The teams, work, and reported result are consistent across the two disclosures. The achieved improvement remained 10%, while the application evolved from a tool for specific development tasks into a lever for managing service-delivery capacity.[1][2]
What Hitachi's 10% productivity gain means
The latest figure represents the productivity improvement achieved with AI in domestic IT service delivery as of the end of FY25. Management also set an internal target of 30% for FY27, while calling that goal ambitious and saying how much could be achieved was still unclear.[1]
Hitachi did not disclose the 10% figure's baseline, denominator, measurement method, or number of projects covered. It therefore cannot be interpreted directly as a 10% reduction in labor hours or used to infer an equivalent change in revenue, profit, or headcount.
The potential financial path remains unquantified
The business path from higher productivity is greater service capacity. Hitachi said AI-driven productivity could allow its constrained IT resources to meet more customer demand. If that additional capacity converts into more projects, it could increase revenue and reduce the labor required per project, supporting DSS operating profit. Project demand, pricing, staffing, project management, and other business changes can also affect the outcome, however, and the company has not isolated this application's contribution to DSS operating profit.[1]
What is confirmed is that AI is being used in Hitachi's domestic IT service delivery workflow and has produced the productivity improvement reported by management. What remains unknown is the number of projects covered and the incremental revenue or operating profit generated by AI-assisted projects compared with other projects.

Original: So as of the end of 25, 10% of the productivity improvement was achieved. So we're trying to push this number up. So for the next year, FY27, this number goes up to 30% from 10%. So that's the internal target.
Translation: As of the end of FY25, productivity improvement had reached 10%. We are working to increase it further; for the next year, FY27, the internal target rises from 10% to 30%.
