This report presents findings from the OpenTelemetry Japanese Community Survey, conducted to understand the current landscape of OTel awareness, adoption, and community engagement among developers and engineers in Japan. The survey targeted practitioners across roles such as development, SRE, DevOps, and Platform Engineering, distributed through CNCF community channels and Japanese social platforms like X (formerly Twitter), Qiita, and Zenn. The goal was to develop data-driven strategies that can meaningfully grow OTel usage and engagement within Japan’s tech ecosystem.
