Jun Maekawa [updated]

Maekawa frequently employs precise, sometimes challenging, squash folds and reverse folds to achieve his detailed shapes.

This theorem is critical because it dictates what local fold patterns are physically possible. For example, if a vertex has four creases (a common occurrence), the only possible mountain-valley assignments that satisfy the theorem are 3 mountains/1 valley or 3 valleys/1 mountain. This simple rule prevents impossible folding configurations and is a foundational axiom used in computational origami and foldability algorithms. jun maekawa

Jun Maekawa may not be a household name, but his influence is rippling through the world of sustainable design. By weaving together material science, energy systems, and human‑centric design, he demonstrates that architecture can be an active participant in healing the planet—rather than a passive consumer of its resources. At any interior vertex of a flat-folded crease

At any interior vertex of a flat-folded crease pattern, the number of mountain folds (M) and valley folds (V) must differ by exactly 2. and human‑centric design
