Ryota was born in Tokyo, Japan in 1981. He graduated from Soka University (Tokyo) in 2004 with a B.S. in Bioengineering. In 2009 he received his Ph.D. (Marine Science), also from Soka University. Ryota worked for Soka University as teaching staff from 2009-2012. By becoming interested in the deep-sea, he moved to JAMSTEC, the deep-sea research institution in Japan, as a postdoc researcher. Ryota started his work on coral reef ecology in the Scripps Institution of Oceanography in 2016, supported by the Japanese government.


My wife and I have 3 wonderful daughters.
