en.Wedoany.com Reported - Amazon Web Services Japan introduced multiple AI Agent application cases during the keynote speech at "AWS Summit Japan 2026." Akihiko Shirahata, Representative Executive Director and President of the company, revealed that after Blue Origin introduced 2,700 AI Agents, work that originally took several years was reduced to just a few days. Currently, approximately 70% of the company's employees are using AI Agents.
To enhance company-wide productivity, Sony has built an enterprise-level large language model (LLM), which has been used by over 65,000 people, processing 150,000 inference requests daily.
Dave Brown, Senior Vice President of AWS Compute, AI, and Services Infrastructure, emphasized in his speech that AI Agents are driving automation across a wide range of scenarios, including application development, customer service, and decision-making. He pointed out that unlike old-style AI assistants that can only answer human questions, AI Agents like Amazon Quick allow users to simply state the desired outcome, and the Agent autonomously fills the gaps between tools and executes tasks. Such Agents can perform cross-referencing reasoning across sources like email, Slack, documents, and data lakes, automatically completing decisions and document creation, thereby eliminating the need for manual information stitching.
Software development is one of the most prominent areas of automation application. A new method called "AI-Driven Development (AI DLC)" is fundamentally transforming the development cycle. Masashi Uta, Managing Executive Officer (CITO and CISO) of Tokio Marine & Nichido Fire Insurance, appeared as a guest and noted that the insurance business relies on over 800 systems, which severely constrains development speed, and AI DLC offers a breakthrough opportunity. From requirement definition to source code, all output materials required for development are generated by AI, while critical decisions are left to humans. This has accelerated the development speed of a certain business system by a factor of ten. Since the process from requirement definition to design and implementation flows smoothly, humans can focus on essential judgments. Prototyping that previously took six months when outsourced can now be completed in one day, and costs have been reduced from millions of yen to the daily usage fee of "kiro," an Agent-based development tool provided by AWS.
