WHirotugu Akaike was a Japanese statistician. In the early 1970s, he formulated the Akaike information criterion (AIC). AIC is now widely used for model selection, which is commonly the most difficult aspect of statistical inference; additionally, AIC is the basis of a paradigm for the foundations of statistics. Akaike also made major contributions to the study of time series. As well, he had a large role in the general development of statistics in Japan.

WToshiyuki Kobayashi is a Japanese mathematician known for his original work in the field of Lie theory, and in particular for the theory of discontinuous groups (lattice in Lie groups) and the application of geometric analysis to representation theory. He was a major developer in particular of the theory of discontinuous groups for non-Riemannian homogeneous spaces and the theory of discrete breaking symmetry in unitary representation theory.

WNarutaka Ozawa is a Japanese mathematician, known for his work in operator algebras and discrete groups. He has been a professor at Kyoto University since 2013. He earned a bachelor's degree in mathematics in 1997 from the University of Tokyo and a Ph.D. in mathematics in 2000 from the same institution. One year later he received a Ph.D. in mathematics from Texas A&M University. He was selected for one of the prestigious Sloan Research Fellowships in 2005 and was an invited speaker at the 2006 ICM in Madrid. He has won numerous prizes including the Mathematical Society of Japan (MSJ) Spring Prize and the Japan Society for the Promotion of Science (JSPS) Prize.
