In 1988, he joined the Central Research Laboratory of ASAHI KASEI CORPORATION, where he worked on the development of ternary permanent magnet materials, thin-film solar cells and wide-band-gap semiconductors materials.
In 1999, he became an Associate Professor of the Kochi University of Technology (KUT) in Kochi, in 2002, he became a Professor and the Head of Materials Design Center, Research Institute of KUT (KUT_MADEC) in 2004.
His research interests focus on nanotechnology, optoelectronic thin films and devices made from wide-band-gap semiconductors such as ZnO.
He is a member of the Japan Society of Applied Physics of Japan and Society for Information Display (SID). He has been the supervisor of several National Projects. He won a prize by the Ministry of Education, Culture, Sports, Science and Technology for his work on ZnO-based Transparent Conductive Oxides (TCO)
films for use in Liquid Crystal Display (LCD)-TV and thin-film solar cells in 2011.
