About “3D Embroidery Sayoko”
3D Embroidery Sayoko is an embroidered art form that weaves life with thread, transcending the flat surface to achieve sculptural, three-dimensional expression.
Through 3D Embroidery Sayoko, Sayoko Kitai creates lifelike embroidered works inspired by nature— insects, animals, and plants—faithfully capturing their vitality and presence.
Self-taught in embroidery, she made her first public submission in 1991 to the National Embroidery Competition organized by The Mainichi Newspapers. Her tapestry My Dream Room, in which furniture, plants, and birds were all expressed entirely through three-dimensional embroidery, received the Grand Prize.
Following this achievement, she pursued an idea long considered impossible in conventional embroidery: creating works that are as beautifully finished on the reverse side as on the front. This led to the development of her original technique, Double-Sided 3D Embroidery, in which stitching the front simultaneously completes the reverse. The technique was officially trademarked in 1999.
Deeply inspired by the beauty of natural forms, she has devoted particular focus to butterflies, conducting extensive research into the shape, movement, and texture of their wings. By adjusting thread tension and needle angle stitch by stitch, and by using single strands of ultra-fine threads—thinner than cotton—as well as platinum and pure gold threads, she successfully reproduces the delicacy, brilliance, and even the opening and closing motion of butterfly wings.
This resulted in the establishment of her signature three-dimensional embroidered butterfly brooches, fully sculptural works that can be appreciated from all 360 degrees.
By combining this embroidery technique with her own innovative wire techniques, she creates works whose wing shapes can be freely adjusted, giving them an appearance as if they were truly alive.
Jewelry created through 3D Embroidery Sayoko is both wearable art and art to be displayed and enjoyed in the home.
In 2018, following a solo exhibition in Nihonbashi, she met the late Yumi Katsura. In 2019, her 3D embroidered works were featured in dresses for the Paris and Tokyo Collections.
In 2022, a platinum butterfly brooch received the Iron Award in the Jewelry Category at a prestigious international design award in Italy.
In 2023, she was honored as a Distinguished Craftsman of Chiba Prefecture.
In 2024, she received the National Distinguished Craftsman Award (Modern Master Craftsman of Japan).
In 2025, she was awarded the Yellow Ribbon Medal in recognition of her decades of research, creation, the establishment of original techniques, and her outstanding achievements. She was granted the honor of an audience with His Majesty the Emperor at the Imperial Palace.
Weaving life with thread, transcending the flat plane into three dimensions, and giving form to emotion.
3D Embroidery Sayoko will continue to explore the limitless possibilities of embroidery.
