This is the official website of the Coastal Biogeochemistry Laboratory at the University of Tokyo, managed by Toshihiro Miyajima (D.Sc.), Atmosphere and Ocean Research Institute at Kashiwa Campus. We have been working for about 25 years on the biogeochemistry and ecology of coastal marine ecosystems, focusing primarily on vegetated coastal habitats and coral reefs.
