Title: The Ultimate Guide to Folding the Ryujin 3.5: Updated Tutorial & Tips

Origami Ryujin 35 — Evolution, Significance, and the Art of Complexity

The Ryujin 3.5 — often stylized as Ryujin 35 to denote its lineage and the approximate crease count many folders use — is one of the most celebrated contemporary origami models. Designed by Satoshi Kamiya in 2006 and iteratively refined by countless folders, the Ryujin family blends mythology, technical rigor, and aesthetic subtlety. An essay on the Ryujin 35 must address its origins, structure, cultural resonance, and the broader implications for origami as both craft and artform.

Origins and Designer Intent Satoshi Kamiya, a Japanese origami designer noted for his intricate, lifelike creatures, conceived the Ryujin as an interpretation of the dragon—an archetypal figure in East Asian mythos symbolizing power, wisdom, and natural forces. Kamiya’s Ryujin models are not simple stylized dragons; they are attempts to render musculature, scales, horns, and expressive poses out of a single uncut square of paper. The Ryujin 3.5 (or Ryujin 35 in casual shorthand) represents an intersection of refinement and accessibility within Kamiya’s oeuvre: less forbidding than his most extreme works but still demanding advanced technique and planning.

Structural Complexity and Design Principles At its core, the Ryujin 35 showcases principles common to high-end figurative origami: efficient paper allocation, hierarchical flap division, and controlled layering. To achieve a dragon’s limbs, tail, mane, and myriad scales, the designer must map a complex tree of limbs onto the square paper’s geometry. This process—known as “circle-packing” or “flap-allocation” in modern mathematical origami—balances competing needs: long, narrow flaps for limbs and tail; many small flaps or pleats for scales; and a central mass for body and head. The Ryujin 35’s crease pattern embodies that balance, often combining sink folds, multiple reverse folds, and closed/open sinks to funnel paper where detail is needed without creating unusable bulk.

Aesthetics: Realism and Stylization What sets the Ryujin apart is its ability to suggest organic anatomy while retaining the abstract purity of folded paper. Scales are typically rendered by repeated pleating or tessellated crimping along the tail and body; horns and claws arise from tapered, well-executed folds that preserve sharp points. Successful folders aim for a sense of motion—an S-curve tail, a poised head, dynamic wings (if present)—so the model reads not as a static assembly of creases but as a creature caught mid-action. Paper choice and finishing (wet-folding, careful shaping) play significant roles in translating the crease plan into lifelike texture and stance.

Cultural and Community Impact The Ryujin models have become touchstones within the origami community. They are often used as benchmarks of technical ability: folding a convincing Ryujin signals mastery of advanced techniques like closed-sinks, multiple-layer management, and careful shaping. Tutorials, diagrams, and video walkthroughs for Ryujin variants have proliferated online, creating shared vocabulary and technique among folders worldwide. Moreover, the model has inspired derivative works—simplifications for intermediate folders, hyper-detailed versions for the hyper-ambitious, and hybrid designs that combine Ryujin elements with other creatures. This dialog between designer intent and community innovation is characteristic of contemporary origami’s living tradition.

Pedagogy and the Role of Tutorials The Ryujin 35 occupies an important pedagogical niche. It requires folders to synthesize many advanced skills, making it an excellent project for structured study: crease pattern reading, pre-creasing strategy, layer management, and shaping. Modern tutorials range from annotated crease patterns to step-by-step photo guides and time-lapse videos; each format supports different learning styles. Importantly, effective instruction on the Ryujin emphasizes not only how to make each fold but why: where the paper must remain thin, where to hide bulk, and how small adjustments in pre-creasing affect final proportions.

Materiality: Paper and Technique Choosing paper for Ryujin 35 is a study in tradeoffs. Thin, strong papers (e.g., unryu, tissue-foil, or high-quality kami variants) allow complex crease networks without excessive bulk; prepared papers (tissue-foil laminated to non-woven tissue) enable bold shaping and durable hold. Wet-folding can soften edges and lend a sculptural, muscular look but risks losing fine points. Many folders use larger squares (e.g., 50–70 cm) to allocate more paper per limb, yielding cleaner details. The Ryujin’s demands thus push practitioners to explore materials and finishing techniques, advancing the craft as a whole.

The Ryujin and Origami’s Evolving Identity Beyond technical discussion, Ryujin 35 illustrates origami’s shifting identity: from traditional ceremonial practice to a contemporary design discipline informed by mathematics, computation, and global exchange. Designers now use algorithmic tools to simulate circle-packing and plan crease patterns; folders exchange discoveries on forums and social media; and exhibitions treat complex origami as fine art. The Ryujin sits at this nexus—deeply rooted in myth and paper tradition, yet emblematic of forward-looking craftsmanship.

Challenges and Criticisms Some critics argue that ultra-complex models like the Ryujin prioritize technical virtuosity over expressive clarity—a display of difficulty rather than distilled design. Others counter that the challenge is intrinsic to realizing certain aesthetic goals: intricate anatomy simply requires intricate paper allocation. There is also an accessibility concern: extreme complexity can create high barriers for newcomers. The community has responded by producing tiered tutorials, simplified variants, and collaborative learning spaces to keep the field inclusive.

Conclusion The Ryujin 35 is more than a demanding folding pattern; it is a cultural artifact of modern origami—where mythology, mathematics, material science, and community converge. Its elegant combination of structure and expressiveness makes it a landmark model that encourages technical growth, creative adaptation, and deeper appreciation of what can be coaxed from a single square of paper. Whether approached as a personal challenge, a teaching piece, or a study in design, the Ryujin invites folders to engage with origami’s most compelling possibilities: transforming the flat into the living, the simple square into a vessel of narrative and form.

Phase 3: The Scales (The "Reverse" Technique)

This is the most time-consuming part of the tutorial. The dragon’s body is covered in individual scales formed by reverse folds.

The Updated Strategy: Old tutorials often fold the scales one by one as you shape the body. The updated, cleaner method is:

1. Pre-crease the Scales: Fold the "fish scale" creases into the strip of paper that will become the body before you collapse the base.
2. Accordion Fold: Create the accordion structure for the body first.
3. Crimp and Shape: Use the pre-creased lines to pop the scales out. This results in sharper, more uniform scales and prevents the paper from tearing under stress.

Final Rating: ⭐⭐⭐⭐ (4/5)

One star removed for the lack of shaping instructions and high entry barrier. But as a technical achievement, it’s a 5/5. If you’re ready to suffer beautifully, go for it. If not, try Kamiya’s Phoenix 3.5 or Wizard first.

Folding the Ryujin 3.5 by Satoshi Kamiya is widely considered one of the most difficult challenges in the world of origami. Because it is a "super complex" model that can take a month to complete, there is no single "updated" tutorial that covers every step in a standard 10-minute format. Instead, most folders rely on a combination of community-developed guides, lessons from experts like Daniel Brown, and specific module tutorials. Core Phases of Folding Ryujin 3.5

Most updated tutorials break the process into these critical sections:

Preparation & Paper Choice: Use a square of paper at least 1.5 to 2 meters per side. Specialty papers like "Origamido" or treated tissue-foil are often recommended for their strength and thinness.

Pre-creasing: This is the most time-consuming stage, involving the creation of thousands of intersecting grid lines for the scales and transition units.

Scaling (The "Blighters"): The model features over 2,000 scales. Tutorials often focus on "fast methods" for shaping these using tools like toothpicks or mechanical pencils to poke and tuck the paper into curves.

Transition Units: Specialized folds that transform wide pleats into the smaller ones required for the legs and head.

Collapsing: Bringing the pre-creased paper into its final 3D form. Key tutorials focus on the most difficult collapses:

The Head: Often done as a live "head collapse" demonstration because of its complexity.

The Legs: Requires precise mountain and valley folds to connect diagonal creases.

The Neck Twist: Considered the third most difficult step, where the base of the head must be flipped over at the neck. Where to Find Guides & Diagrams
