Brief Introduction:
Takaaki Kajita is a Japanese physicist and a professor at the Institute for Cosmic Ray Research, University of Tokyo. In the early 1990s, he led Japan–U.S. collaboration in the construction of the Super-Kamiokande detector. Completed in 1995, the facility contains a 50,000-ton water tank and brought together about one hundred leading researchers. Through precise observations of atmospheric neutrinos, the research team provided the first compelling evidence of neutrino oscillations, demonstrating that neutrinos have mass and overturning the assumption of zero neutrino mass in the Standard Model of particle physics. This groundbreaking achievement earned Professor Kajita the 2015 Nobel Prize in Physics.
Over the years, Prof. Kajita has continued his research in neutrinos and gravitational waves. Such research relies heavily on large-scale and highly sophisticated experimental facilities. From construction to data analysis, these endeavors require extensive international collaboration. These experiences have led him to recognize that scientific cooperation across national and cultural boundaries not only advances academic research and expands scientific achievements, but also serves as an important force in promoting international understanding and world peace.
