In April 2021, the Okinawa Environmental Research Support Section (OERSS) was renamed the Environmental Science Section. The section itself was established in 2019 as an independent function of the OKEON Chiramori Project with the goal of maintaining and promoting OIST's Okinawa terrestrial field research and community network in a more sustainable and stable manner.

Our goal is to carry out environmental research and education to ultimately contribute to the sustainable development of Okinawa by leveraging the local relationships, environmental monitoring networks, and experienced support teams developed by the OKEON Churamori Project.
