It is interesting to see how citizen science in Japan is enacted and how the concept of citizen science is dependent to the social and cultural context. Also looking at it not only from a top-down perspective, where universities or organizations are involved, but also the bottom-up perspective that includes only those practices that are done by citizens alone opens up a new space. As I am currently engaging with research on air pollution in different sites, I could build from this text in considering the link between "citizen-driven approaches and institutional imparatives in the governance" (p. 7) of issues with air pollution.
