JPX Market Innovation & Research (JPXI), with the support of Amazon Web Services (AWS), has made significant progress towards Japan Exchange Group (JPX)’s goal of becoming a “global, comprehensive finance and information platform,” as outlined in its Medium-Term Management Plan.
JPXI has developed J-WS, JPX’s common infrastructure platform, on AWS.
The platform supports the stable operation of JPX Group’s data and digital services while improving operational quality and functionality through AWS’s advanced cloud technologies.
As part of its ongoing digital transformation, JPXI will migrate the Timely Disclosure Network (TDnet) to J-WS.
TDnet plays a critical role in transmitting material corporate information swiftly and accurately to the market and investors. By moving this semi-essential system, second only to JPX’s trading and clearing system, to J-WS, JPXI aims to enhance system stability, resilience, and cybersecurity.
The migration will incorporate a multi-layered redundant configuration utilising both JPX’s existing Business Continuity Plan (BCP) environment and AWS’s Asia Pacific (Tokyo) and Asia Pacific (Osaka) Regions, significantly strengthening resilience against large-scale disruptions.
JPXI is collaborating with Fujitsu Limited to upgrade TDnet’s infrastructure and functionality.
This includes improving performance and processing capacity for disclosure materials.
To support listed companies facing increasing disclosure requirements, JPXI is also developing a new service using AWS’s generative AI to assist in preparing disclosure documents.
Future plans include a dedicated platform to securely connect JPX’s exchanges and listed companies, facilitating seamless information management and enhanced support.
JPXI also plans to enhance the transmission speed and machine readability of disclosure data and make it accessible through APIs to external platforms.
This will help build an ecosystem where financial institutions, information vendors, and startups can collaborate to develop new value-added services using a common data infrastructure.
With support from the AWS engineering team, including AWS Prototyping and AWS Professional Services, JPXI has strengthened its internal development capabilities and nurtured digital talent.
This approach has enabled the rapid delivery of key projects, such as the Carbon Credit Market System, developed with Hitachi, and J-LAKE, JPX’s integrated data services platform.
JPXI has also utilised AWS’s data analytics tools to improve the way market information is disseminated.
Built on J-WS, J-LAKE consolidates JPX’s market and alternative data, enabling advanced analysis using AI, machine learning, and generative AI.
A new feature on the JPxData Portal now allows users to efficiently search for disclosure materials and identify investment opportunities.
Satoshi Futagi, President and CEO of JPX Market Innovation & Research, said:
“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 and digital businesses, has collaborated with AWS to build several new systems to support these businesses.”
Scott Mullins, Managing Director, Worldwide Financial Services at AWS, said:

“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.”
