This analytical approach made him a central figure in the "origami sekkei" (technical origami) movement of the 1980s and 90s, alongside contemporaries like Robert Lang and Toshiyuki Meguro. This movement moved away from trial-and-error folding and toward "crease patterns"—blueprints of lines drawn on paper that dictate exactly where the folds should go.

In origami, a model is often judged by its "cleanliness"—how efficiently the paper is used. Maekawa is a master of efficiency. His style is often described as "demonstrative" or "structural." jun maekawa origami

Consider a single vertex where multiple creases intersect. For the paper to lie flat without self-intersecting, the sum of alternating angles must equal 180 degrees. By analyzing the angular order around the vertex, Maekawa proved that the total number of creases n must be even, and the parity constraint (M – V = ±2) must hold.

Maekawa is most famous for popularizing the use of —the complex web of lines visible when a folded model is unfolded—as a primary design tool. His most significant contribution to the scientific community is Maekawa’s Theorem , which deals with the "flat-foldability" of a model. The theorem states that at any given vertex in a flat-foldable pattern, the number of mountain and valley folds must always differ by exactly two. This fundamental rule allows artists to predict whether a complex design can actually be folded flat, providing a mathematical foundation for the intricate models seen today.
