Where Color Becomes Time
Otsuki Yosuke
Otsuki Yosuke is a leading figure in contemporary Japanese glass art, known for his distinctive approach to multilayered glass that fuses technical precision with deeply personal memory. Working between craft and sculpture, he creates works in which color is never merely decorative, but a vessel for time itself. His works invite viewers into a slow unfolding of perception, where surface and depth continuously negotiate with one another.
The Architecture of Color
At the core of Otsuki’s practice is what he calls a “combination of techniques.” Rather than relying on a single specialization, he brings together blowing, casting, cutting, and polishing—disciplines that are usually separated into different hands.
This integrated approach led him to develop his signature multilayered glass, in which sheets of colored glass are fused, ground, and reassembled through repeated firing. The process is slow and exacting: each piece may take up to two years, shaped entirely by hand from concept to final surface. The result is not a static form, but a structural field where geometry, transparency, and depth fluidly interact.
Color in Motion, Memory in Form
Otsuki refers to his works as “Memories of Colors,” a title that reflects both their physical construction and their conceptual grounding. These pieces translate personal experience into chromatic sequences, where gradients echo moments of passage, return, and reflection.
In recent years, he has expanded his approach from horizontal layering—like geological strata—to vertical compositions that shift with the viewer’s movement, creating what he describes as a cinematic experience. As light travels through these layered surfaces, color appears to breathe and dissolve, revealing a quiet instability that is central to his vision: glass as something not fixed, but continuously unfolding in time.
Biography
Otsuki Yosuke was born in 1972 in Yokohama, Japan. He graduated in 1997 from the 3D Design Department (now Department of Ceramic, Glass, and Metal Works) Glass Program, Tama Art University. Since 1997, Otsuki has exhibited widely across Japan in both solo and group exhibitions, steadily establishing his practice within contemporary Japanese glass art.
His work has received numerous awards and critical recognition. Major honors include the Grand Prize at the 40th Kanagawa Prefectural Art Exhibition (2004), the Japan Kogei Association Prize at the 27th Traditional Kogei Craft Exhibition (2019), and the Minister of Education, Culture, Sports, Science and Technology Award at the 28th Traditional Kogei Craft Exhibition (2021). In 2020, one of his Memories of Colors works was selected for the 66th Japan Traditional Kōgei Exhibition and acquired by the Imperial Household Agency.
