Forty years after Yukawa predicted the existence of mesons, experimental research activities with the use of mesons were started in Japan. Particles of the "second generation," which have nothing to do with the structure of ordinary materials, such as muons, K mesons, and other exotic particles have been exploited as unique probes to study new constituents of matter.
