Named in honor of the Nada Junior and Senior High School in Kobe, which is known as one of the most excellent high schools in Japan. The first discoverer teaches science, especially astronomy and geology, there. Established in 1927, the school has the mottoes “make good use of your energies” and “live and let live prosperously”. These are the same as the mottoes of Kodokan Judo Institute. “Nada” means “the sea that is difficult to cross”. (M 15091) _ _.
