JPX Market Innovation & Research, Inc. (JPXI) has announced progress in its efforts to transform Japan Exchange Group, Inc. (JPX) into a “global, comprehensive finance and information platform.” This initiative is supported by Amazon Web Services (AWS), as outlined in JPX’s Medium-Term Management Plan.
JPXI has built J-WS, JPX’s common infrastructure platform, on AWS. This move has improved the stability and functionality of the JPX Group’s data and digital businesses. The company plans to migrate the Timely Disclosure Network (TDnet), which distributes important corporate information to investors, onto J-WS. TDnet is considered essential for maintaining investor confidence and market fairness. The migration aims to strengthen system stability, resilience, and cybersecurity.
The new configuration will use both JPX’s existing Business Continuity Plan environment and AWS’s Asia Pacific regions in Tokyo and Osaka. This approach is expected to improve TDnet’s ability to withstand wide-area disasters.
To further support corporate disclosures, JPXI is working with Fujitsu Limited to upgrade TDnet’s infrastructure and performance. The upgrades will also introduce features that use AWS’s generative AI technology to help companies prepare disclosure materials more efficiently. Additionally, a dedicated platform will be provided for secure management of information between exchanges and listed companies.
JPXI intends to enhance the speed at which disclosure data is transmitted and improve its machine readability by sharing it through APIs with external platforms. This could foster collaboration among financial institutions, vendors, and startups using a shared data infrastructure.
In response to changing market conditions and customer needs, JPXI has developed digital talent within its organization with help from AWS engineering teams such as AWS Prototyping and Professional Services. These efforts have enabled rapid development of projects like the Carbon Credit Market System with Hitachi Ltd., as well as J-LAKE—an integrated data services platform created mainly by JPXI engineers.
To manage large volumes of financial and non-financial data from over 3,900 listed companies releasing more than one million pages of disclosure annually, JPXI uses AWS technologies for advanced analytics through platforms like J-LAKE. A new feature on the JPxData Portal combines this system with generative AI so users can search disclosure materials more efficiently.
Looking ahead, JPXI plans continued cooperation with AWS while exploring further cloud integration for critical functions at JPX.
Futagi Satoshi, President & CEO of JPX Market Innovation & Research, Inc., stated: “In its long-term vision ‘Target 2030,’ JPX expressed its intention to turn into a ‘global, comprehensive finance and information platform,’ and it has been working to enhance the appeal of Japan’s financial and capital markets as a whole. JPXI, whose role within the JPX Group is to spearhead the group’s next-generation data/digital businesses, has collaborated with AWS to build several new systems to support these businesses.
As a result, the ecosystem that JPX has developed using AWS’s solutions has been steadily expanding. Going forward, JPXI will continue to enlist the support of its powerful partner AWS to further rev up efforts to turn JPX into a ‘global, comprehensive finance and information platform.'”
Scott Mullins, Managing Director for Worldwide Financial Services at Amazon Web Services (AWS), commented: “By migrating its mission-critical TDnet system to AWS and using our cloud infrastructure across Tokyo and Osaka regions, JPX is improving resilience and stability while expanding access to Japan’s financial markets. AWS’s experience supporting financial institutions, combined with its advanced capabilities in Generative AI, machine learning, and high-performance computing enables JPX to deliver greater innovation through their data and digital initiatives. Together we’re working to make Japan’s capital markets more efficient and transparent.”
