His current interest is to search for new physics beyond the standard model in particle physics, by studying rare neutral kaon decays. He and his colleagues are now busy preparing for a new experiment for the J-PARC high intensity proton accelerator.

After receiving a PhD at Tokyo University, he became a postdoc at Fermilab in the U.S. and then a Wilson Fellow. After 7 years, he became an Associate Professor at Osaka University in 1992, and then a Professor in 2001. He was a cospokesperson for Fermilab KTeV-799 experiment, and is a spokesperson for J-PARC E14 experiment.
The only way to learn how to become a physicist and how to run experiments is by taking a responsibility of one of the detectors or projects. That is also the way to enjoy experiments.
