Yoshitomo Saito was born in 1958 in Tokyo, Japan. He spent his first nineteen years of schooling period at the same educational institution called Jiyu-Gakuen (Freedom School) in Tokyo. This unusual mono-schooling experience at the small private Christian school naturally made a profound impact on him. One of the most significant impacts on the matter of artistic merit came from its visual cultural environment. Since this school is housed in the marvelous architecture by the renowned American architect Frank Lloyd Wright (built in 1921), and other newer structures by his direct disciples, Saito, from early age on, had to grow up surrounded by the strong taste of authentic Wright expressions. His interest in the world of independent artistic voices was nourished in this line of peculiarly unique esthetic environment.

Saito came to the United States in 1983 to study American studio glass art at the Penland School of Crafts in North Carolina. He then moved to the Bay Area to attend California College of the Arts in Oakland. At CCA, he studied glass under Marvin Lipofsky and sculpture under Dennis Leon and Linda Fleming. He began using bronze during this period and received his MFA in Sculpture in 1987.

In 2006, the artist moved to Colorado in search of new and affordable live and work situation to pursue the lifestyle of fully engaged independent artist. He now operates his private studio foundry at Ironton Studios. His work is represented by Haines Gallery in San Francisco and Michael Warren Contemporary in Denver.
