菊計数：自然の数式、花の芸術

Where the elegance of floral design meets the precision of mathematics.

The Kiku Keisū Philosophy

At Kiku Keisū, we believe nature is the ultimate artist and mathematician. From the Fibonacci sequence in a sunflower's seeds to the fractal geometry of a fern, every petal and leaf tells a story of elegant order. Our mission is to bridge the worlds of botanical art and mathematical principles, creating arrangements and educational experiences that celebrate the profound, hidden patterns of the natural world. We aim to inspire wonder and a deeper appreciation for the intricate design woven into the fabric of existence.

Through our creations and workshops, we illuminate the 'Ma' (間) – the intentional use of empty space in Japanese aesthetics – and apply mathematical precision to achieve balance and harmony, ensuring each piece is a reflection of nature's inherent wisdom and beauty.
