Unit Polyhedron Origami—often referred to as modular origami —is the art of creating complex, multi-faceted geometric shapes by assembling multiple identical folded pieces of paper called "units". Unlike traditional origami, which typically uses a single sheet of paper, unit origami allows folders to construct larger, more stable 3D structures that often resemble regular polyhedra like cubes, octahedrons, and icosahedrons. The Master of the Craft: Tomoko Fuse

Building a unit polyhedron typically involves several distinct stages:

: A hallmark of her style is the use of "tabs" and "pockets" to lock units together without the need for adhesives.

The term is most closely associated with the work of Tomoko Fuse , a world-renowned origami artist whose book, Unit Polyhedron Origami, serves as a definitive guide for both beginners and experts. Fuse's designs are celebrated for their:
