JPX Market Innovation & Research, Inc. (JPXI), with the support of Amazon Web Services (AWS), is advancing its efforts to help Japan Exchange Group, Inc. (JPX) become a “global, comprehensive finance and information platform,” in line with JPX’s Medium-Term Management Plan.
JPXI has established J-WS, a common infrastructure platform for JPX, using AWS cloud technologies. This platform supports stable operation of the group’s data and digital businesses and aims to enhance both quality and functionality. As part of these improvements, JPXI plans to migrate the Timely Disclosure Network (TDnet)—a system essential for quickly transmitting material corporate information—to J-WS. The migration will improve TDnet’s stability, resilience, and cybersecurity by leveraging AWS’s Asia Pacific regions in Tokyo and Osaka alongside JPX’s existing business continuity systems.
The upgrade also includes enhancements to TDnet’s performance and capacity for handling disclosure materials. Fujitsu Limited is collaborating on these upgrades by contributing its technical expertise from previous work on TDnet. To assist companies facing increased workloads due to growing investor demands for disclosures, JPXI is implementing new services that use AWS generative AI to streamline the preparation of disclosure documents. A dedicated platform will connect exchanges with listed companies for secure information management and advanced support.
JPXI intends to further improve how disclosure data is transmitted and shared through APIs and other methods. These steps are expected to foster an ecosystem where financial institutions, vendors, and startups can collaborate using a unified data infrastructure.
To meet evolving market conditions and customer needs, JPXI has focused on developing timely financial services. With guidance from AWS engineering teams—including AWS Prototyping and Professional Services—JPXI has built internal development capabilities that have enabled rapid launches such as the Carbon Credit Market System with Hitachi Ltd., and J-LAKE, an integrated data services platform developed by JPXI engineers.
Using AWS digital technologies and analytics services, JPXI seeks to improve dissemination of information across markets. Over 3,900 companies are listed on JPX exchanges; each year they produce more than one million pages of disclosure materials covering financial as well as ESG-related topics. The J-LAKE system manages this data centrally using AI tools for sophisticated analysis.
A new feature combining J-LAKE with generative AI has been introduced on the JPxData Portal securities data platform to help users efficiently search disclosures and identify investment opportunities. Future updates will continue improving portal functionality using digital technologies.
Looking ahead, JPXI plans ongoing collaboration with AWS while exploring long-term cloud use for critical functions at JPX as it works toward becoming a global finance platform.
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 of 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.”
