Reiji Hiramatsu was born in 1941 (Showa 16) in Tokyo. The work that he displayed in the Seiryu-sha Exhibition in 1960 was awarded the Spring Exhibition Award and Honorable Mention. He received first prize for his painting in the 10th Edition of the Yamatane Museum of Art Awards Exhibition in 1988. In 1984, he participated in the formation of Yoko no Kai — a joint effort founded with the goal of exhibiting freely from the constraints of organizations — where he would go on to present his works for a decade. He assumed the role of professor at Tama Art University from 1994-2005. The year 2006 saw the opening of the Reiji Hiramatsu Hall at the Yugawara Art Museum, becoming a permanent location to exhibit his works. In 2013, the Giverny Museum of Impressionisms in France hosted a solo exhibition of Hiramatsu’s works, with the exhibition traveling to the Museum of Asian Art in Berlin the following year. He is currently a trustee for the Nihon Bijutsuka Renmei (Japan Artists Association) and Japan Arts Council and is an associate professor at Juntendo University.
