Apr. 28, 2026 JPX Progress of AI Utilization Under Medium-Term Management Plan 2027

Japan Exchange Group (“JPX”) aims to provide value that focuses on the specific needs of a diverse group of stakeholders that includes investors and listed companies, while ensuring the fairness and transparency of the market and continuously building markets that are stable and credible. Based on this approach, JPX has stated in the “Medium‑Term Management Plan 2027,” which commenced in FY2025, its policy of proactively utilizing AI and other advanced technologies, which it has positioned as one of the main management initiatives.

In this context, we would like to introduce JPX’s initiatives thus far regarding AI, as well as outline our future outlook.

1. Convey the Appeal of the Japanese Market—Supporting New Discoveries With AI

In addition to the fact that information on listed companies used for making investment decisions is primarily qualitative, the increasing volume and variety of information, combined with language barriers, has significantly increased the burden of searching for and understanding information for both domestic and overseas investors. As a result, it is becoming increasingly difficult to grasp all relevant information manually. To address these challenges, JPX will progressively roll out information provision services that utilize generative AI. By reducing barriers such as the increasing volume of information and differences in language, JPX is working to foster a market environment that is easier for market participants to understand, while also supporting the discovery of new investment opportunities. These new information provision services that utilize generative AI will continue to be expanded going forward. In addition, by incorporating AI‑driven development into the development process, JPX will continue to offer services while accelerating deployment to the production environment and, simultaneously, enhancing quality.

Examples of services that utilize generative AI

JPX Market Explorer

This service organizes and provides listed companies’ financial information and business overviews in an easy‑to‑understand, multilingual format, enabling market users in Japan and overseas to efficiently understand a wide range of stock information.

JPxData Portal

Using generative AI to analyze disclosure documents and earnings reports, this service assigns tags based on keywords and business details, allowing users to search for and compare companies based on services or product names even when the name of the company is not known.

J-LENS

This service offers an AI‑powered search function for disclosure documents, enabling users to retrieve the information they need using natural language queries.

Since the launch of the above services, they have attracted more interest than initially expected, and utilization has steadily increased. Actual access data and search trends indicate strong demand for information among market participants. Taking these usage patterns into account, JPX is continuously improving functionality and expanding content. Going forward, JPX aims to provide even more valuable information by making improvements based on users’ opinions and data.

Alongside these efforts to enhance the visibility of information related to listed companies through the utilization of generative AI, JPX is planning to offer a new service that utilizes AI and other technologies, as part of the related services of TDnet, which is currently undergoing renewal. This service is designed to support the tasks performed by listed companies throughout the entire process, including the preparation and creation of disclosure documents. Through this, JPX aims to support timely and easy‑to‑understand information disclosure and contribute to enhancing the transparency and credibility of the market as a whole.

2. Pursuit of a Safe Investment Environment—Enhancing Market Credibility With AI

Japan Exchange Regulation, whose mission is to ensure and enhance market fairness and credibility, has been utilizing AI in its market surveillance operations since 2018 to investigate unfair trading practices such as market manipulation. By referencing AI‑based scoring, staff are now able to focus on more advanced analysis and surveillance. In the use of AI for market surveillance operations, JPX continues to verify its accuracy and implement necessary improvements to ensure it remains adaptable to the ever-changing market environment. In light of factors such as recent advances in generative AI, JPX is promoting the utilization of AI across a wider range of operations and is working to enhance and improve efficiency of self-regulatory functions through cross-departmental AI utilization and other efforts.

In listing examination operations, AI is being used to enhance the collection and analysis of information related to fraud risks at initial listing applicants. In addition, for listed company compliance and trading participants examination and inspection operations, AI is increasingly being used to analyze compliance with laws, rules, and regulations by listed companies and securities firms.

In addition to these efforts, generative AI is actively being utilized to improve efficiency in day‑to‑day tasks such as document preparation and to facilitate the sharing of knowledge among staff across various operations. Through these, Japan Exchange Regulation is promoting the further advancement and deepening of its overall self‑regulatory functions to ensure and enhance market fairness and credibility.

3. JPX Evolving Together With AI—Organizational Integration and Human Resource Development

In addition to the initiatives described above, numerous AI‑related projects are underway at JPX. Supporting these projects is a company‑wide AI promotion framework launched in FY2025. Through the AI Promotion & Communication Committee, which comprises the Corporate Strategy Department; IT Planning Department; and IT Business Department and is chaired by CEO Yamaji, management reviews policies and priorities while promoting the utilization of AI across the organization. By appointing persons in charge of AI promotion in each department to coordinate their respective AI projects, JPX is promoting the utilization of AI at the operational level. The committee monitors and supports initiatives across departments, reports to management as appropriate, and works to promote these efforts throughout the organization.

Under this framework, JPX is developing an AI‑enabled working environment by providing employees with internally developed generative AI applications as well as general‑purpose tools such as Microsoft 365 Copilot, while also advancing human resource development initiatives. These efforts are working to foster an environment where employees can accumulate the skills and knowledge required to use AI effectively, allowing them to focus on work that provides even more value. An internal survey indicates that the use of AI has resulted in an average monthly reduction of approximately 12 working hours per employee, demonstrating that the promotion of AI utilization at JPX is making a substantive contribution to productivity improvement and the establishment of a foundation for value creation.

JPX will continue to advance operational reform and human resource development in an integrated manner through the use of AI, with the aim of enhancing its expertise and appeal as an organization responsible for operating market infrastructure with a high degree of public visibility.
