JPX Market Innovation & Research, Inc. (JPXI) is advancing its efforts to transform the Japan Exchange Group, Inc. (JPX) into a “global, comprehensive finance and information platform” with support from Amazon Web Services (AWS). This initiative aligns with JPX’s Medium-Term Management Plan and aims to enhance the competitiveness of Japan’s financial markets.
A central part of these efforts has been building J-WS, JPX’s common infrastructure platform, on AWS. This move has improved operational quality and functionality for JPX Group’s data and digital businesses by leveraging AWS’s cloud technology expertise.
JPXI announced it will migrate the Timely Disclosure Network (TDnet)—a key system for transmitting material corporate information—to J-WS. TDnet plays an essential role in maintaining investor confidence by ensuring timely disclosure of information. The migration is expected to strengthen stability, resilience, and cybersecurity for TDnet through a redundant configuration that includes both JPX’s Business Continuity Plan environment and AWS’s Tokyo and Osaka regions.
The upgrade plan also involves working with Fujitsu Limited to improve TDnet’s performance and capacity for processing disclosures. New features will utilize AWS generative AI technology to assist companies in preparing disclosure materials. JPXI plans to offer a secure platform connecting exchanges directly with listed companies, enabling advanced support and integrated management of disclosure processes.
Further enhancements include increasing the speed and machine readability of disclosure data while sharing it via APIs with external platforms. This is intended to help financial institutions, vendors, and startups collaborate using shared infrastructure for developing new services.
With guidance from AWS engineering teams—including Prototyping and Professional Services—JPXI has focused on cultivating digital talent internally. These developments have contributed to launching projects like the Carbon Credit Market System (with Hitachi) and J-LAKE, an integrated data services platform developed mainly by JPXI engineers.
To address growing volumes of information—over 1 million pages annually from more than 3,900 listed companies—JPXI uses J-LAKE on J-WS for centralized market data management and analysis using AI technologies. A new feature on the JPxData Portal combines generative AI with J-LAKE to help users efficiently search disclosures and identify investment opportunities.
Looking ahead, JPXI plans further collaboration with AWS as it explores expanded cloud use across critical functions while pursuing its goal of establishing JPX as a global finance hub.
Futagi Satoshi, President & CEO of JPX Market Innovation & Research, Inc., commented: “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), stated: “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.”
