Motoichi Ohtsu was born in Yokohama, Japan in 1950.

In 1978, he was appointed a Research Associate, and in 1982, he became an Associate professor at the Tokyo Institute of Technology. From 1986 to 1987, while on leave from the Tokyo Institute of Technology, he joined the Crawford Hill Laboratory, AT&T Bell Laboratories, Holmdel, NJ. In 1991, he became a Professor at the Tokyo Institute of Technology. In 2004, he moved to the University of Tokyo as a professor.

He has been the leader of the “Photon Control” project (1993-1998: the Kanagawa Academy of Science and Technology, Kanagawa, Japan), the “Localized Photon” project (1998-2003: ERATO [Exploratory Research for Advanced Technology], JST[Japan Science and Technology Agency], Japan), “Terabyte Optical Storage Technology” project (2002-2006: NEDO [New Energy and Industrial Technology Development Organization], Japan), and “Near field optical lithography system” project (2004-2006: Ministry of Education, Japan). He is concurrently the leader of the “Nanophotonics” team (2003-prsent: SORST [Solution Oriented Research for Science and Technology], JST, Japan), “Innovative Nanophotonics Components Development” project (2006-present: NEDO, Japan), and “Nanophotonics Total Expansion: Industry-University Cooperation and Human Resource Development” project (2006-present: NEDO, Japan).


He received the B.E., M. E., and Dr. E. degrees in electronics engineering from the Tokyo Institute of Technology, Tokyo, Japan, in 1973, 1975, and 1978, respectively.
