Osaka University Yukawa Memorial conducts a variety of activities in support of people aspiring to tackle new areas of learning.


Hideki Yukawa was engaged in research in physics as a lecturer and assistant professor at the School of Science of former Osaka Imperial University from 1933 to 1939. In 1934, Yukawa announced a breakthrough paper and presented his idea that the pi meson (pion) mediates nuclear forces that bind the protons and neutrons in the nucleus at the center of the atom. The meson whose existence was predicted by Yukawa was discovered in 1947. In December 1949, Hideki Yukawa was awarded the Nobel Prize in physics. Osaka University Yukawa Memorial was established in 1953 in honor of his research achievements at Osaka University. Yukawa Memorial has been serving its purpose successfully thanks to the support and efforts of many people including the successive generations of Osaka University President.
