Amazon Web Services (AWS) has announced its support for JPX Market Innovation & Research, aiming to advance the Japan Exchange Group's (JPX) objective of becoming a global finance and information platform. This collaboration is set to enhance market infrastructure, data systems, and disclosure technology.
According to JPX’s official news release, JPXI—JPX’s data and digital arm—is partnering with AWS to accelerate JPX’s long-term "Target 2030" vision. The collaboration aims to boost the international appeal and competitiveness of Japan’s financial instruments markets while strengthening technological capabilities. It also outlines multi-track work across infrastructure, disclosure, and data services that underpin JPX’s modernization agenda.
The press release further states that JPXI has developed J-WS—JPX’s common infrastructure platform—on AWS to operate JPX Group’s data/digital businesses with enhanced stability and functionality. It adds that the mission-critical Timely Disclosure Network (TDnet) will migrate to J-WS, adopting redundant architecture across AWS Asia Pacific (Tokyo) and Asia Pacific (Osaka) Regions. This move aims to increase resilience against wide-area disasters and bolster cybersecurity. The document emphasizes TDnet’s importance as a semi-essential system—second only to trading and clearing—highlighting the significance of moving disclosures onto AWS-backed infrastructure.
Finextra reports that the AWS-backed program includes upgrading TDnet’s performance and capacity while incorporating features using AWS generative AI to assist issuers in preparing disclosure materials. The report notes JPXI's plan to improve transmission speed and machine readability of disclosure data, distributing it via APIs to support a broader ecosystem of institutions, data vendors, and startups. These steps align with rapid development and launch of key projects such as JPX’s Carbon Credit Market System and the integrated data platform J-LAKE.
