Origami Ryujin 3.5 Tutorial May 2026

The origami internet is littered with half-finished Ryujin 3.5s. The completion rate is estimated at less than 5% for first-time attempts. To finish it is to understand Kamiya’s genius: the realization that the crease pattern is not a set of instructions, but a physics equation. The dragon exists inherently in the grid; you are simply reminding the paper of its shape.

When you finally place the last scale, curl the last claw, and mount the 1.5-meter creature on a wooden plaque, you will not feel joy. You will feel quiet exhaustion. And then you will look at the pile of failed attempts in the corner, and you will fold a crane to honor the paper you sacrificed.

Final Note: There is no tutorial for the Ryujin 3.5 that holds your hand. There are only forums, crease patterns, and the silent rage of a Sunday afternoon. Good luck. You will need a bigger sheet of paper.

Completing the Ryujin 3.5 is an exhausting ordeal that can take anywhere from 15 to 30 hours depending on your skill level. You will encounter frustration. You will likely rip a scale or two. But when you hold the finished model—a majestic, serpentine dragon with a saw-toothed belly and sweeping horns—you will have achieved something permanent.

The tutorial is a map, but the journey is yours alone. Approach the paper with respect

The Ryujin 3.5 (Dragon God), designed by Satoshi Kamiya, is widely considered one of the most complex origami models ever created, often taking master folders anywhere from 60 to over 200 hours to complete. Because it is a "Super Complex" model, there are no traditional step-by-step diagrams; instead, it is folded from a Crease Pattern (CP). Essential Preparations

Paper Size: A square sheet of at least 1.5 to 2 meters per side is recommended. While a 1-meter square is possible, the thousands of scales become nearly impossible to fold at that scale.

Paper Type: You need extremely thin but strong paper, such as Wenzhou, Single Tissue, or O-Gami. Many folders treat the paper with methylcellulose (MC) to add crispness and strength.

Time Commitment: Expect to spend roughly one month on the project. The Folding Process

The process is generally divided into four major phases: Pre-creasing, Collapsing, Connecting, and Shaping. 1. Pre-creasing (The Foundation)

This is the most time-consuming phase, where you mark every single line from the Crease Pattern onto your paper.

Grid System: Most of the model is based on a dense grid (often or higher). origami ryujin 3.5 tutorial

Scale Pre-creasing: You must pre-crease over 2,000 scales. A common technique involves initiating the scale folds by establishing initial lines and then using a time-lapse-like repetition to finish the body.

Leg and Foot Units: Detailed work is required to pre-crease the leg scales and underbelly pleats. 2. The Collapse

Once pre-creased, you must "collapse" the paper, turning the flat sheet into a 3D form. Ryujin 3.5 FULL HEAD COLLAPSE Tutorial [Satoshi Kamiya] #8

The Ryujin 3.5, designed by Satoshi Kamiya, is widely considered one of the most complex origami models ever created, often taking master folders over a month to complete from a single sheet of paper. There is no single "all-in-one" video for this model; instead, the process is broken down into highly technical stages: preparation, pre-creasing, and specific section collapses like the scales, head, and legs. 1. Preparation & Materials

Success with the Ryujin 3.5 begins with selecting the right paper. For a successful fold, experts recommend:

Paper Type: Use very thin, strong paper like double tissue or sketching paper under 60gsm.

Size: A square of at least 1.5 meters (150cm) per side is recommended, though some attempt it with 1.2 meters.

Grid: You must first divide the paper into a massive 96x96 grid.

Tools: Keep small clips and a pointy tool (like a toothpick or X-Acto knife) ready for shaping the thousands of scales. 2. Pre-Creasing (The Foundation)

This stage involves marking every single fold before the final "collapse."

Scales & Legs: You will need to pre-crease the complex diamond patterns for the leg scales and feet. The origami internet is littered with half-finished Ryujin 3

Checkpoints: Many folders follow FoldingPhoenix's multi-part series which covers pre-creasing the scales in meticulous detail. 3. The Collapse (Assembly)

Once the paper is fully pre-creased, you begin the "collapse," where the flat sheet starts taking its 3D dragon form:

The paper was no longer just a square; it was a battlefield of pre-creases. For three days, Kenji had lived within the grid of a 64x64 division

To fold the Dragon God was to dance with madness. The tutorial sat open on his screen, a silent witness to the carnage of crumpled foil-paper in the corner of the room. The Trial of the Scales The true test began with the

: Every pinch-fold was a prayer. His vision blurred as he moved through the repetitive "molecule" of the scales, a process that takes most folders over 40 hours just to pre-crease. The Collapse

: Then came the "collapse." This is the moment where the flat paper must suddenly become three-dimensional. It is the most common point of failure. One wrong tug, and the structural integrity of the dragon’s core would tear. The Spirit of the Fold : He remembered the tutorial’s warning: “Do not rush the transition.”

The Ryujin 3.5 isn't just a model; it's a test of whether you can respect the paper's limits. The Awakening As the sun rose on the fifth day, Kenji performed the final . He dampened the paper slightly—a technique called wet-folding —to give the dragon its lifelike curves.

The head, with its intricate horns and whiskers, finally emerged from the chaotic mess of pleats. The Ryujin 3.5 stood on his desk, three feet of coiled, mythical power, its scales catching the morning light like armor. He hadn't just followed a tutorial; he had survived a rite of passage. breakdown of the specific paper types recommended for a model as complex as the Ryujin?

Fold the paper into 80ths. You cannot measure this with a ruler; you must fold using reference points. Completing the Ryujin 3

Once the scales are done, the "flat folding" stage concludes, and the "3D shaping" begins. The tutorial will guide you through the collapse—folding the head, the horns, the wings, and the tail.

Satoshi Kamiya published the diagrams for the Ryujin 3.5 in his book, Works of Satoshi Kamiya 2: 2002–2009. However, calling them "diagrams" is generous. The model is so complex that the instructions are often just reference points.

Why is it so hard?

Most "tutorials" you find online are not full step-by-step guides; they are crease pattern (CP) walkthroughs. If you want to fold Ryujin 3.5, you must learn how to read a Crease Pattern.
