The current status of major facilities for positron production in Japan and China, as well as recent progress on their applications, are reported. Emerging measurement techniques and their applications including an idea for future collaborations are also discussed. All speakers are invited from the organizer, and the session is held under the auspices of the organizing committee of JWPS2019.
