After studying art colleges, Senkichiro Nasaka enters the Kyoto City Painting University: encounters Kazuo Shiraga who is in the same class. Nasaka makes a career switch from Japanese painting to Oil painting in 1960s. It is until in 1965 that Nasaka presents his work to the 15th Gutai Art Echibition and becomes member of Gutai Art Association subsequently. During his Gutai period, there is a great change in the style from tableaux works influenced by Art Informel to hardedge imagery such as light art and kinetic art, which becomes representative style of the later Gutai. At Guggenheim Museum’s retrospective exhibition Gutai: Splendid Playground in 2013, Nasaka reproduces his past work made of aluminum tubes, which are running across the whole exhibition space like a scaffold. Nevertheless, the works from his early period of Gutai, characterized by nuanced marriage of various colors are particularly in high demand among collectors.
