About Spiral of Life Glass Tableware
In a fusion of mathematical structure and kinetic art, the Spiral of Life project presents a new direction for Kiriko glassware. This work captures the organic fluctuation of nature within a glass medium. The development originated from a collaboration between the designer and Ree, a paint dancer. By translating Fibonacci sequences into movement, Ree provided the conceptual framework for the design. Through 8 to 13 and 13 to 21 spiral ratios, the artisan connects traditional craft with biomathematics. The resulting harmony offers a rhythmic experience reflecting the natural pulse of the world.

Interviews
Design Interview
What is the main principle, idea and inspiration behind your design?
The main inspiration is the relationship between the sun and the sunflower, specifically the Fibonacci spiral found in nature. The breakthrough came when I watched my daughter Ree, a paint dancer, physically manifest this sequence by synchronizing her movements with Fibonacci numbers. Seeing this inspired me to transpose this blend of mathematical law and organic asymmetry onto Kiriko glass.
What has been your main focus in designing this work? Especially what did you want to achieve?
My main focus was on expressing an organic fluctuation that resists simple geometric repetition, even while following strict mathematical laws. Instead of relying on traditional Kiriko grids, I aimed to recreate a living trajectory by maintaining the Fibonacci count while manually adjusting each cut.
What are your future plans for this award winning design?
The design is currently being applied for registration and will receive copyright protection for registered designs in Japan in December 2027. Following that, in line with KJ studio's mission, I plan to expand this beautiful design across items like wine glasses, soba cups, and rock glasses to enrich users' daily lives.
Behind the Design
Press Kit
Credits, team members and technical details provided by the designer.
- Unique Properties
- Fibonacci spirals follow strict mathematical laws yet appear organic and asymmetrical, resisting simple geometric repetition. Traditional Kiriko requires precise vertical and horizontal guidelines before cutting; however, standard grids cannot capture this natural fluctuation while ensuring reproducibility. To solve this, I developed a hybrid approach: maintaining the Fibonacci count with guidelines while manually adjusting each cut to ensure a smooth, living trajectory.
- Dimensions & Packaging
- The product dimensions are as follows: The rock glass is 77mm in diameter and 92mm in height, as shown in the main image. In optional image #1, the wine glass is 58mm in diameter and 150mm in height. In optional image #2, the soba cups are 81mm in diameter and 62mm in height. In optional image #3, the sake cup is 60mm in diameter and 60mm in height. Finally, the top views of the sake cup and soba cup filled with water are shown in optional image #4.

- Production Technology
- The double-layered glassware is carefully ground and polished by hand using Japanese Kiriko cut glass technology.
- Design Challenge
- Through rigorous prototyping, I established a specialized system. Smaller vessels like sake cups use an 8 to 13 spiral ratio, while larger items like wine and rock glasses employ a 13 to 21 ratio to maintain proportion. For vessels with decorative bases, such as a soba cup, I meticulously integrated an 8 to 13 spiral on the bottom to enhance aesthetic coherence. This precise scaling was essential to capturing the Spiral of Life across the entire collection.
- Research
- A true Fibonacci spiral requires clockwise and counterclockwise counts to be adjacent numbers in the sequence. To ensure visual balance and mathematical integrity, I conducted extensive research to determine the optimal pairings, such as 8 to 13 or 13 to 21, based on specific glass diameters and curvatures. This study ensured that the mathematical beauty remains consistent.
- Inspiration
- I initially struggled to translate the relationship between the sun and the sunflower into glass. The breakthrough came via my daughter Ree, an artist and paint dancer, who shared my fascination with the sunflower Fibonacci spiral. This pattern blends mathematical law with organic asymmetry. Ree physicalized this sequence by synchronizing her leg drawn spiral counts with Fibonacci numbers. Witnessing this kinetic manifestation inspired me to transpose these complex spirals onto Kiriko glass.
- Project Duration
- The project started in December 2025 in Tokushima, Japan, and finished in February 2026.
- Operation Flow
- The streamline motifs are executed with wide-angle V cuts. When viewed from the side, patterns on the far surface refract through the front, creating complex layered intersections that evoke the mystery of life. From a top-down perspective, the precise Fibonacci sequence achieves a profound, harmonious balance. The design invokes a rhythmic and engaging experience, mimicking a living pulse. This interaction between light and geometry brings dynamic vitality to the glassware.
- Patents
- The design is being applied for design registration and will receive copyright protection for registered designs in December 2026 in Japan.

To demonstrate the rhythmic harmony and life-like pulse of the design, the video showcases the glassware in rotation. This highlights how the patterns shift and intersect dynamically as the perspective changes, illustrating the Spiral of Life concept through the interaction of light, shadow, and the intricate Kiriko hand cuts.
