Ohba was born in Shizuoka Prefecture, Japan in 1981. He graduated from Kyoto University of Art and Design in 2005 (Mixed Media Course at Department of Fine and Applied Arts), and completed the master’s degree program in Oil Painting at the Fine Arts Department from Tokyo University of the Arts in 2007. Since his early works, he often creates light by incorporating polarized pearl, gold and holographic paint into his paintings. Throughout the history of painting, light expressions have been created by various attempts in bringing together color (CMY) and light (RGB), which have fundamentally different principles. Current trends in art, optical art and impressionism, for instance, are in fact addressing the issues of light and visual perceptions. Japanese arts and crafts techniques, such as gold foil leaf and raden (mother-of-pearl inlay), have brought direct light into artistic expression and is perhaps more advanced than Western art. Ohba inherits the idea of these techniques in utilizing light as an element and develops with an extremely contemporary approach. His works have been exhibited extensively in Japan and overseas, including “Parallel Histories: The Several Currents of Contemporary Art” (2020, Shizuoka Prefectural Museum of Art) and the “VOCA Exhibition - The Vision Of Contemporary Art 2011”, (The Ueno Royal Museum, Tokyo).. His works have been acquired by the JAL Sakura Lounge at the Haneda Airport, Japan, the Long Museum (Shanghai), and the Shizuoka Prefectural Museum of Art, etc. OHBA is currently taught as an associate professor at his alma mater, Kyoto University of Art.
