Sakamoto paints in sections, without making preliminary sketches on the canvas. She believes that “every move is a turning point” in the painting process. In principle, she does not go back to a previous section, but completes the work piece by piece. Under this rule, distortion naturally occurs in the painting space as the plastic elements proliferate on the canvas. Sakamoto's most famous work is a distorted space covered with tiles, a characteristic element of her early paintings, in which women who look like her alter egos are portrayed. In recent years, Sakamoto has been deepening her approach to painting in a more theoretical manner, with particular attention to the figurative experiments on form production by various artists in the past.
Sakamoto graduated from Aichi Prefectural University of the Arts with a MFA and a DFA in Oil Painting.
