If you’ve ever played kendama for a while, you’ve probably experienced the frustration of a frayed, twisted, or even broken string. Whether it’s from too many whirlwind tricks, tangled messes, or just everyday wear and tear, a bad string can ruin your flow. But don’t worry—fixing a kendama string is easier than you think.

I’ve been playing kendama for years, and I remember the first time my string snapped mid-trick. It was during a practice session with friends, and I had no idea how to replace it. After fumbling through a few failed attempts, I finally figured it out. Now, I can swap out a string in minutes, and I want to help you do the same.

Why Do Kendama Strings Wear Out?

Before diving into the fix, it’s important to understand why kendama strings get damaged in the first place. This can help you extend the life of your next string.

Common Reasons for String Damage:

• Friction and tension – The string constantly rubs against the tama (ball) and ken (handle), wearing it down.
• Knot slippage – If the knot at the tama or ken isn’t secure, it can loosen, causing unnecessary stress on the string.
• Overuse and tricks – Advanced moves like whirlwind, lunar flips, and juggles put extra strain on the string.
• Tangles and twists – If the string gets tangled, it can develop weak spots, making it more likely to break.
• Cheap strings – Some kendamas come with lower-quality strings that fray or snap more quickly.

Now that you know what causes string problems, let’s get into how to fix them.

Step 1: Gather Your Tools

Before you start, make sure you have everything you need:

• A replacement string (usually 50–70 cm long)
• A stringing tool (a small wire loop that helps thread the string through the tama)
• A pair of scissors (for trimming excess string)
• Tape (optional, to secure knots)

Most kendamas come with a spare string and a stringing tool. If you don’t have one, you can make your own by bending a thin wire into a loop.

Step 2: Remove the Old String

If your string is still attached but needs replacing, follow these steps:

• Untie the knot at the tama and remove any washers or spacers.
• Pull the string through the tama hole (you might need to wiggle it a bit if it’s tight).
• Unthread the string from the ken, making sure to note how it was originally looped.

If the string is broken, simply pull out the remaining pieces.

Step 3: Thread the New String

This is where things get tricky if you’ve never done it before, but with practice, it becomes second nature.

How to Thread the String Through the Tama:

• Use the stringing tool – Insert the wire loop through the tama hole.
• Slide the string through the loop – Pull it through gently until the string comes out the other side.
• Make sure it’s centered – Both ends should be roughly equal in length.

How to Attach the String to the Ken:

• Loop the string through the ken hole – The string should go through the hole near the spike.
• Adjust the length – Most players prefer a string length between 50–70 cm, depending on personal preference.
• Tie a secure knot – A double or triple knot works best to keep it from slipping.
• Check for tangles – Make sure the string flows smoothly without twists.

Step 4: Secure the Knot and Adjust the String

Now that the string is in place, it’s time to make sure everything is set correctly.

• Test the knot – Give it a gentle tug to ensure it won’t come undone.
• Check the string length – Too short, and tricks become harder; too long, and it gets tangled.
• Spin the tama – Make sure the string moves freely without kinks.

If the string feels off, adjust the knot or length before playing.

Step 5: Playtest and Fine-Tune

Before jumping into your usual tricks, take a few minutes to test the setup:

• Do a few basic tricks – Try a simple lighthouse or big cup catch to see if the string moves smoothly.
• Check for snags – If the string catches anywhere, it might be too tight or twisted.
• Make final adjustments – If needed, re-tie the knot or tweak the length.

Once everything feels right, you’re good to go!

Bonus: Tips to Extend the Life of Your Kendama String

Now that you’ve fixed your kendama string, here’s how to keep it in good shape for as long as possible:

• Use high-quality strings – Some brands offer thicker, more durable strings.
• Avoid excessive twisting – If the string starts coiling up, let the tama spin freely to reset it.
• Store your kendama properly – Keep it in a cool, dry place to prevent unnecessary wear.
• Check for fraying regularly – If you notice small frays, replace the string before it snaps mid-game.

Fixing a kendama string might seem like a small task, but it makes a huge difference in your gameplay. I remember the first time I struggled to change mine, and I know how frustrating it can be when your tricks are thrown off by a bad string. But once you get the hang of it, it becomes second nature—just like landing your favorite trick.

Now that you know how to replace a kendama string, you can get back to honing your skills without any interruptions. So go ahead, fix that string, and keep playing!
