Matsumoto emigrated from Fukuoka, Japan to Melbourne in the mid-1980s, where she began working at an art restoration and framing business in Collingwood. Until her disappearance in 1999, she is known to have produced dozens of forged oil paintings, focussing particularly on the Australian Impressionist Frederick McCubbin. While not all of these were successful a significant number are known to have been certified as authentic and entered into circulation on the art market, as well as the collections of various major institutions such as the National Gallery of Australia and the National Gallery of Victoria.
Matsumoto’s history and activities have been the focus of artist Amy Stuart’s research since 2019.
