TSUMIKI by Kengo Kuma — 7 Pieces

A little architecture, shaped by your imagination. Designed by renowned Japanese architect Kengo Kuma, TSUMIKI transforms a simple set of wooden blocks into an ever-changing sculpture for your home. Stack, balance, and rearrange the 7 pieces to create an airy tower, a miniature pavilion, or a composition entirely your own.

Meaning “wooden blocks” in Japanese, TSUMIKI invites open-ended exploration. Display a creation on a shelf or desk, then take it apart and begin again. It is a thoughtful gift for architecture and design lovers, or anyone who enjoys making something with their hands.

Architecture in its simplest form

Inspired by the coniferous cedar trees from which they are made, the triangular forms leave openings for light and air to pass through. Each arrangement explores the relationship between structure and space. For Kuma, the connection is personal: hours spent playing alone with wooden blocks as a child helped inspire his path into architecture.

Japanese cedar, carefully crafted

The blocks are made from unfinished sugi (Japanese cedar) grown in Morotsuka, Miyazaki Prefecture, home to a more trees forest. The cedar comes from FSC®-certified forests managed with environmental, social, and economic sustainability in mind, and the packaging carries the FSC® mark.

The precisely calculated forms require delicate, accurate craftsmanship that cannot be achieved through machine production alone. Each piece is carefully made by hand, bringing together the natural warmth of wood and the care of its maker.

About more trees design

Established in 2010, more trees design connects cities and forests through objects made with Japanese timber and regional craftsmanship. Working with leading designers and local communities, the brand develops products that celebrate the texture and warmth of wood while encouraging the use of domestic timber.

The brand grew out of more trees, the forest conservation organization founded in 2007 by musician Ryuichi Sakamoto. Guided by the idea of “more trees,” the organization supports forest regeneration through thinning projects in Japan and tree planting overseas. A portion of product sales is donated to more trees to support its forest conservation work.
