Origami - Ryujin

The defining feature of the Ryujin is its dorsal and ventral scales. From a topological perspective, the paper is a continuous surface (genus 0: a disk). To create scales, Kamiya employs a . Each scale is an isosceles right triangle of paper that is folded to stand perpendicular to the body’s spine.

2,000+ individual scales that cover the body in a meticulously shaped texture.

The Ryujin is exclusively a model. Unlike 22.5-degree origami (which uses diagonal folds), box pleating relies on a grid of perpendicular lines (usually a 48x48 or 96x96 division). This grid allows for parallel, repeating structures—essential for scales. The scales are formed by a cascade of "sink folds" arranged in staggered rows, similar to a staggered array in crystallography. The defining feature of the Ryujin is its

For centuries, origami was bound by the restriction of a single, uncut square of paper. Traditional models (cranes, frogs, lilies) utilized fewer than 30 steps. In the late 20th century, masters like Akira Yoshizawa and Robert Lang broke this barrier by introducing wet-folding and computational design. However, the (2005) stands as a singularity in this trajectory. With over 1,000 steps requiring hundreds of hours of labor, it depicts a Japanese dragon (Ryujin) with individual scales, horns, claws, and a sinuous body. This paper argues that the Ryujin’s significance lies in its solution to a specific geometric paradox: how to generate infinite surface detail (scales) from a finite, continuous medium (paper). Each scale is an isosceles right triangle of
