Hiroshi Yajima is a Japanese furniture designer associated with quiet, functional forms, natural timber, and refined detailing. His work reflects a contemporary Japanese approach to furniture. It is restrained in appearance, practical in use, and attentive to the tactile qualities of wood.
Among his best-known works is the FORMS collection for Nissin Furniture Crafters, also known as Nissin Mokkou. The collection includes chairs, stools, armchairs, sofas, and barstools. All are characterised by rounded surfaces, slim profiles, and a careful balance between lightness and structural clarity.
Forms Stackable Stool
The Forms Stackable Stool demonstrates Yajima’s ability to turn a modest object into a refined design statement. Its circular seat, compact proportions, and timber construction give it an informal warmth. At the same time, its stackable structure makes it useful in homes, cafés, studios, and hospitality interiors.
The stool’s appeal lies in its combination of visual softness and practical storage. Its rounded seat reduces the visual weight of the object. Meanwhile, the stackable frame allows multiple stools to be stored vertically without dominating a room. This is a particularly Japanese solution. It is simple, space-conscious, and elegant without being decorative for its own sake.
Notable Designs
- Forms Stackable Chair: A solid wood and veneer plywood chair with a rounded seat and stacking capacity. Its practical form makes it suitable for both residential and commercial settings.
- Forms Stackable Stool: A compact stool with a circular seat, designed for vertical stacking and space-saving storage.
- Forms Arm Chair: A timber-framed armchair with a wide, thin seat back, designed to provide support without unnecessary bulk.
- Forms DC Sofa: A sofa design combining timber structure with fabric or leather upholstery, extending the language of the FORMS collection into lounge furniture.
Collaboration with Nissin Furniture Crafters
Yajima’s work is closely connected with Nissin Furniture Crafters, a Japanese manufacturer based in Hida Takayama, Gifu, an area long associated with skilled woodworking. Founded in 1946, Nissin Mokkou developed a design language that combines the craft traditions of Hida with the clean lines of Scandinavian modern furniture.
This partnership helps explain the quiet strength of the FORMS collection. The furniture is not minimal in the sense of being cold or severe. Instead, it is warm, tactile, and resolved through proportion, joinery, and material discipline.
Design Philosophy
Yajima’s design philosophy can be understood through three recurring principles: simplicity, utility, and material honesty. His furniture avoids excessive ornament, but it is not anonymous. The rounded seats, slim backs, and carefully proportioned frames create a sense of softness within a disciplined modern structure.
The FORMS collection also reflects a broader tradition in Japanese design where restraint is not merely aesthetic, but ethical. Objects are expected to serve daily life, respect space, and age gracefully. Wood is not disguised; its grain, tone, and touch become part of the experience of the furniture.
Why It Matters
The Forms Stackable Stool is a small object, but it captures many of the concerns central to contemporary furniture design. These include compact living, flexible interiors, sustainable material choices, and the continuing value of craft. Its success lies in being useful without appearing utilitarian, and refined without becoming precious.
For those interested in contemporary Japanese furniture, Hiroshi Yajima’s work offers a clear example of how modern design can remain warm, human, and materially grounded.
