Untitled

Sadamasa Motonaga's Untitled (1965) exemplifies the spontaneity and expression characteristic of Art informel. As a key figure in postwar Japanese abstract art, Motonaga’s work reflects a dynamic, energetic style rooted in abstract expression. The piece employs gestural techniques and textured surfaces, emphasizing materiality and process over representational detail. Its title, Untitled, invites viewers to engage with the artwork purely through its form, gesture, and texture, embodying the core principles of Art informel—a focus on spontaneity, improvisation, and the raw act of creation.
