The PCST Symposium 2025, held in Tokyo from 11–13 November, marked the first PCST-related event hosted in Japan. The symposium explored the strategic development of science communication in Asia, focusing on education and training, as well as public engagement. Navigating challenges such as linguistic diversity, limited professional development, and underrepresentation in Western discourse, Asian science communicators are harnessing new platforms and networks to expand local engagement and international impact through culturally rooted narratives.
