Field of Research

He is widely known for his achievement on the production and characterization of endohedral metallofullerenes and novel　carbon nanotube materials. His research team has been produced, purified and characterized more than 70 endohedral metallofullerenes. His research team recently synthesized the first single-wall carbon nanotubes with metallofullerenes encapsulated inside the nanotubes, which was reported in Phys.Rev.Lett. and Science in 2000 and Nature in 2002. Totally, he has published over 380 original and peer-reviewed scientific papers including approximately 200 in the top physics and chemistry journals , and more than 50 review papers in journals and books. He has also presented a lot of invited lectures/seminars and conference talks. He is also the members of Japan Chemical Society, Japan Physical Society, Japan Mass Spectrometry Society, Materials Research Society (U.S.A.), Electrochemical Society (U.S.A.), American Association for the Advancement of Science (U.S.A.), and serves as referees in many international journals in physics, chemistry, materials science and engineering.
