Japanese exchange operator Japan Exchange Group (JPX) said its AI initiatives have reduced employee workloads by an average of approximately 12 working hours per month, citing an internal survey published on April 28.
The figure comes from a progress update on JPX’s Medium-Term Management Plan 2027, which launched in FY2025 and positions AI as a core management initiative. JPX operates the Tokyo Stock Exchange, Osaka Exchange, and Tokyo Commodity Exchange.
The productivity gains stem from a combination of internally developed generative AI applications and general-purpose tools such as Microsoft 365 Copilot, supported by a company-wide AI Promotion & Communication Committee chaired by Group CEO Yamaji Hiromi.
Investor tools and disclosure support
JPX’s AI rollout extends beyond internal efficiency. The exchange group has launched or expanded several investor-facing services that use generative AI: JPX Market Explorer provides multilingual financial information on listed companies; JPxData Portal uses AI to tag and categorize disclosure documents so users can search by product or service name; and J-LENS, which launched in beta in December 2025, offers natural-language search across disclosure filings.
JPX said usage of these services has “steadily increased” since launch and exceeded initial expectations.
The group is also planning a new AI-powered service linked to TDnet, its disclosure platform, designed to help listed companies prepare and create disclosure documents.
Self-regulatory unit Japan Exchange Regulation has used AI in market surveillance since 2018 to investigate unfair trading practices including market manipulation. AI-based scoring lets staff concentrate on higher-level analysis. JPX said AI is now also being applied to fraud-risk assessment for listing applicants and compliance reviews of listed companies and securities firms.
“JPX has positioned AI not only as a way to improve operational efficiency but also as a foundational element for enhancing the quality of operations and generating new value,” Yamaji said.
