Professor Tatsuhiko Kodama is the head of the Radioisotope Center at the University of Tokyo. On July 27, he appeared as a witness to give testimony to the Committee on Welfare and Labor in Japan's Lower House in the Diet.
This English-subtitled version of his brilliant speech, which was originally uploaded on my now-extinct YouTube channel, has been widely viewed (more than 60,000 views), translated into German and French, and has inspired many people. This speech made Prof. Kodama famous almost overnight.
