How To Make A Origami Ninja Star

Origami Shuriken: The Basic Fold

The thing most people call a ninja star is technically a shuriken. The folding method I use comes from a 1970s Japanese origami book that hasn't been reprinted since 1982. It takes about three minutes once you know the sequence. The first time through, plan on seven. Start with a square of paper. Standard origamikami is eight inches, but I usually cut ordinary printer paper to about six inches because it's lighter and flies better. Thicker paper creases too hard and throws off the balance.

How To Make A Origami Ninja Star From a Single Square

Fold the square in half diagonally, then in half again. You should have a small triangle with four layers. Unfold everything so the paper lies flat with both diagonal creases visible. Now fold each corner into the center point. You'll have a smaller square made of eight triangular flaps. Flip it over. Fold the top corner down to make a triangle, then unfold it. Do the same for the bottom corner. Crease both ways. Take the left corner and fold it inward. The right corner goes the same direction. You're creating the basic diamond shape that all the outer points will emerge from. Press the folds flat with your thumbnail.

Here's where beginners mess up. The paper wants to spring open at this stage. Hold the shape firmly against the table and reinforce every crease. I learned this the hard way when a cheap notebook paper shuriken came apart mid-throw during a school pickup line. Flip the paper over again. Each corner now has two loose flaps pointing outward. Starting from any corner, fold one flap up and over, then tuck the tip underneath the central pocket. Repeat for all four corners. The points should lock into place without glue or tape.

The Throwing Problem Nobody Talks About

A properly folded shuriken with 120 gsm paper cuts through air at roughly forty miles per hour if your wrist snaps correctly. The issue is the release. Most people throw it like a frisbee, which makes it wobble and drop short. You need to let it roll off your thumb and forefinger, not push from the palm. I spent six months trying to get consistent rotation before someone pointed out that my paper weight was wrong. Standard copy paper at twenty pounds gives you about twelve feet of stable flight before the points start fluttering. Switch to fifty pounds and you're looking at twenty-five to thirty feet with decent form. The real trick is the catch. Fold each point flat against the body after throwing. This stabilizes the flight path but makes it harder to spin on impact. For practice, leave the points slightly curled so they catch air differently. You'll see the difference immediately.

Common Mistakes and Why Your Shuriken Falls Apart

Three things go wrong. First, the center pocket isn't tight enough, which means the points slip loose on impact. Second, the diagonal creases aren't sharp, causing asymmetrical flight. Third, and this one surprised me for years, the paper grain direction matters more than anyone admits. Folding against the grain creates micro-tears that weaken the structure after about eight throws. I discovered this when my shuriken started losing points during a weekend tournament in my parents' backyard. The workaround was simple: fold with the grain, not against it. Hold the paper up to a light bulb and watch the shadows. The lines running vertically are the grain. Align your creases parallel to those lines. Another issue is point length. Longer points spin faster but create more drag. Shorter points are more stable but don't look as aggressive. The sweet spot is about three-quarters of an inch from the center pocket to each tip. Anything longer and you're fighting aerodynamics.

Advanced Variations and When They Actually Help

Six-point shuriken exists but requires a different base fold. The math doesn't work as cleanly, and most tutorials online skip the geometry. It takes about twice as long to fold and flies worse for beginners. Don't bother until you can throw the four-point version consistently for fifteen feet. The curved-point variant, which some people claim spins better in wind, actually creates more turbulence. I tested this with a household fan on the lowest setting. The data wasn't promising. Stick with flat points unless you're displaying the folded piece rather than using it.

Storage and Longevity

A finished shuriken stored in a ziplock bag with a silica packet lasts about two years before the paper yellows and the creases weaken. Keep it flat, not stacked. Pressure from other objects causes the points to bend over time. I learned this from experience when my collection from college started developing permanent curl. The solution was to store each piece individually in archival paper sleeves. They cost about four cents each in bulk, but the original creases stay crisp for decades.
