Datadog, Inc., a leading provider of AI-powered observability and security platforms, announced that JR West IT Solutions (J-WITS) has adopted Datadog to enhance the operation of its infrastructure supporting critical services, including “JR Odekake Net,” a comprehensive portal site for railway and tourism information operated by JR West. By utilizing Datadog, J-WITS is supporting the stable operation of public infrastructure services, improving service levels, increasing operational efficiency, and optimizing costs.
J-WITS, as an IT specialist group within the JR West Group, is broadly involved in the design and development of systems that support the safe and stable transportation of railways, as well as systems that support the operations of each JR West Group company, and the development of information infrastructure that supports them. The company has been promoting the development of infrastructure and the modernization of systems, and has adopted Datadog as the foundation that supports the digitalization of the group.
Masahiro Sekifuji, Group Manager of the e-Business Systems I Group, IT Business Solutions Department, Customer Solutions Division, stated: “We introduced Datadog because we encountered challenges when the maintenance service for our self-hosted monitoring software, which we had been using for over 10 years, ended. These challenges included the reliance on individual expertise for creating monitoring scripts, the occurrence of false positives, and the difficulty of sharing monitoring results among team members.”

To address these challenges, we began using Datadog for external monitoring in February 2024. This made it easy to create and share monitoring flows, eliminated reliance on specific individuals for monitoring settings, and expanded the number of people capable of handling monitoring from 2-3 to 15. Furthermore, it has contributed to the stabilization and sophistication of system operations by making it easier to investigate false positives and enabling rapid incident response.
“Because it’s GUI-based, even members who aren’t used to writing scripts can easily use it, and the members’ evaluations during testing were excellent. In addition, Datadog’s pricing model, which is based on the number of records processed rather than the number of users, offered a cost advantage when considering that many users would be using it,” says Sekifuji.
Around the same time, JR West was planning to gradually migrate some of the systems of its comprehensive railway and tourism information portal site, “JR Odekake Net,” from on-premises to AWS. The plan was to modernize the system primarily using serverless architecture to increase its agility. Accordingly, it was decided that the AWS environment would also be monitored by Datadog, and cloud monitoring began in September 2025, coinciding with the launch of the new system on AWS.
” With APM (Application Performance Monitoring), we can now visualize operational data such as logs and metrics across the board, allowing us to quickly grasp the overall status of our services. This supports stable service operation by minimizing delays and failures even during periods of high access, and by providing users with uninterrupted information on various services. Furthermore, we can now accurately report service downtime and impacts to management in the event of a failure, enabling accurate and rapid service improvements and strengthening the overall operational structure of the organization, including improved collaboration between departments. In addition, when Amazon S3 usage costs soared due to a large number of LIST requests, we were able to analyze the request content with APM to identify the cause, modify the API retrieval method, and reduce S3 usage costs by approximately 20%. It also contributed to optimizing AWS Lambda performance during the development phase,” says Haruyuki Hasegawa, Senior Infrastructure Engineer, e-Business Systems I Group, IT Business Solutions Department, Customer Solutions Division, describing the effects of the implementation.
Going forward, we will accelerate incident response and reduce operational workload by utilizing Datadog’s AI agent ” Bits AI SRE, ” and we will also work on automating monitoring using on-call and workflow automation to achieve more advanced system management and troubleshooting. Furthermore, we plan to strengthen our collaboration with JR West, which has adopted Datadog, through regularly held information exchange meetings and other means, thereby further increasing the level of utilization, providing more robust support for public infrastructure services, and further improving service levels.
Kenichi Moriya, Solution Engineering Director at Datadog Japan, stated: “We are delighted that JR West IT Solutions has adopted Datadog to maintain the quality of railway services, which require high real-time information such as operational data, where even slight delays have a significant impact, and where stable operation is essential even during periods of high access. We are honored that Datadog has contributed to simplifying complex operations, enabling rapid troubleshooting, and reducing usage costs as the company’s internal infrastructure operations have changed significantly with the system refresh. Moving forward, we will continue to support the stable maintenance of public services that are vital to society by utilizing AI for automation and expanding the scope of use.”
