Unique Properties
Reinterpreting "KUMIHIMO" from the Edo period-a Japanese historical era (1603-1867), this bag features durability and flexibility through braiding. Minimalist design highlights the pure beauty of the technique. The structure symbolizes "MUSUBI," a concept signifying both physical links and spiritual bonds in Japanese. By joining leather parts with these cords, the design reflects this spirituality, delivering traditional beauty to daily life.
Dimensions & Packaging
Size: H 210 × W 190 × D 150 mm

Production Technology
A work filled with our workshop's craftsmanship.
Consisting of 20 precision leather parts, this bag uses hidden stitching and manual thread finishing to highlight the KUMIHIMO's beauty. Edge-painting on all 100 holes ensures both friction reduction and beauty. The cords were made by the craftsperson Ryuta Fukuda. The fusion of Tsuchiya Kaban’s leather craft and Fukuda’s expertise breathes soul into every detail, embodying the value of traditional craft.
Design Challenge
The challenge of this project was to integrate traditional Kumihimo into a daily bag, balancing harmony with leather and functional beauty. To resolve this, we adjusted the placement of parts by hand in millimeter increments. We strictly managed sewing precision and repeatedly verified knot types and hardware shapes. As a result, we realized a design that fits modern lifestyles, harmonizing two distinct products into a single craft.
Research
Integrating traditional design into modern life.
By researching Kimono culture and modern bag usage, we identified "functionality, tactile feel, and visual balance" as key elements for daily integration. Through three prototyping rounds, we refined leather selection, hardware shape, and braiding to harmonize tradition with modern utility. This research-driven design creates a product ideal for daily use, effectively reaching audiences unfamiliar with traditional crafts.
Inspiration
A bag reinterpreting Japanese tradition for modern life.
This work reconstructs Kimono culture's beauty into a functional bag, harmonizing traditional aesthetics with daily life. Instead of applying crafts as they are, we refined the design to blend into modern wardrobes, removing the distance felt toward traditional crafts. By integrating "KUMIHIMO" into the structure, we aimed to make craftsmanship feel accessible through a modern appeal that invites people to pick it up and experience it.
Project Duration
Started in June 2022 at Tsuchiya Kaban in Tokyo. Mass production was completed at the Tsuchiya Kaban workshop in January 2024, marking the end of the project. It is currently not for sale.
Operation Flow
A versatile bag designed for diverse styles and occasions.
This piece accents casual attire and functions as a sophisticated party bag for formal events. When paired with Kimono, it creates a modern look; its minimal yet deep design enhances any style. It offers two carrying options: a casual, relaxed style like a drawstring bag, and an elegant style using the original metal handle inspired by "Chagama" (a tea ceremony kettle), adding a unique touch to your movements.
