Around 1962, Kazuo Shiraga, Senkichiro's classmate at the Kyoto City Specialist School of Painting, now known as Kyoto City University of Arts, and an eventual member of the avant-garde Gutai group, inspired Nasaka to submit her art to the 15th Ashiya City Exhibition in 1962.
Nasaka was first involved with the Gutai group in 1962 at the Gutai Pinacotheca, which is an exhibition space in Nakanoshima, Osaka.
