He earned his M.Sc. and Ph.D. degrees in condensed matter physics from Tohoku University in Sendai, Japan in 1992 and 1997, respectively. From 1996 to 1999, he worked at the National Research Institute in Inorganic Materials in Tsukuba, Japan. Starting in 1999, he served as a post-doctoral researcher in the Applied Physics Department and later as a physicist at the Stanford Linear Accelerator Center at Stanford University in CA, USA.

In 2003, he joined the National Metrology Institute of Japan (NMIJ) at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan. His work at AIST/NMIJ focuses on metrological applications of the quantum Hall effect, the Josephson effect, and the single electron tunneling effect. Over the years, he has held various positions within NMIJ/AIST, including section chiefs, division head, and group leaders in the fields of electricity and magnetism. Since 2017, he has held the position of Prime Senior Researcher, overseeing new and young researchers at NMIJ. His primary research interests revolve around condensed matter and material physics and their applications in metrology. He is a member of IEEE, JSAP, and IEEJ.

He has contributed to several international and national scientific organizations, serving as the Chair of the Technical Committee on Electricity and Magnetism (TCEM) of the Asia Pacific Metrology Program (APMP) from 2012 to 2015, a Member-at-Large of the CPEM Executive Committee from 2012 to 2020, the Acting Member of the Board of the Tokyo Branch of the Institute of Electrical Engineers of Japan (IEEJ) from 2013 to 2015, and the Chair (domestic) of IEC TC 85 from 2013 to 2016, among others. He also served as a technical advisor of the National Institute of Technology and Evaluation (NITE) of Japan and participated in laboratory assessments, including peer review assessments of other national metrology institutes as a technical assessor or an expert about two to three times per year.

He has encouraged his team members, as well as himself, to collaborate with industry and international counterparts. He has successfully operated or co-operated in over 10 research projects with them. Additionally, he has authored and co-authored over 100 peer-reviewed scientific articles, with more than 10 of them being co-authored with researchers and engineers from industry partners.

AIST has initiated a new quantum project called G-QuAT (Global Research and Development Center for Business by Quantum-AI Technology). This initiative aims to accelerate joint research in quantum-AI computers and quantum sensors with industry and public partner institutions, both domestically and internationally.
