The Yukawa Institute for Theoretical Physics (基礎物理学研究所 kiso butsurigaku kenkyūsho?) is a research institute in the field of theoretical physics, attached to Kyoto University in Japan. It was inaugurated in 1952.
While the center is often referred to as "YITP", this can be confusing as YITP also stands for the C. N. Yang Institute for Theoretical Physics at Stony Brook University in the United States.
In 1949, Japanese theoretical physicist Hideki Yukawa was awarded the Nobel Prize in Physics. He became the first Japanese citizen to receive the Nobel Prize. To commemorate this historic event, the president of Kyoto University immediately proposed to create a memorial hall on campus for Yukawa. In 1950, the Science Council of Japan unanimously resolved a request to the central government to allocate a special funding for the promotion of research in theoretical physics. Enthusiastic discussions among Japanese physicists followed in support for the idea of creating a new institution, similar to the Niels Bohr Institute in Copenhagen or the Institute for Advanced Study in Princeton, New Jersey.
