The Matcha Tea Ritual with the Bamboo Chasen for Matcha: Its History, How to Use It and How to Choose the Best One (Complete Guide)

Few things are as simple—and as powerful—as whisking a good matcha tea with a chasen. It's a small gesture, but it holds a centuries-old tradition, impeccable aesthetics, and the ability to transform a green powder into a beverage capable of pausing, even if only for a moment, amidst the chaos of the day.

If you've made it this far, you probably already know: preparing matcha without a chasen is like trying to dance flamenco without heels. You could do it… but it wouldn't have the same rhythm, the same grace, or the same soul.

In this definitive guide you will learn:

  • What is a chasen and why is it essential?

  • What is it really for?

  • How many bristles should it have and how to choose yours

  • How to use it to get the perfect foam

  • How to care for it and make it last

  • Its history and symbolism in the tea ceremony

  • A selection of the best chasen bags on the market with space for photos

  • And how does all this fit into the Matcha Zen experience?

Let's take it one step at a time.

What is a bamboo chasen and why is it so important?

The chasen is the traditional Japanese whisk for preparing matcha tea. It is handmade from a single piece of bamboo, precisely carved into a fan of very fine prongs. Unlike a metal whisk, the chasen doesn't aim to "stir" the tea; it aims to aerate and transform it .

Its main mission:

  • Dissolve the matcha without lumps

  • Incorporate air to generate a fine and stable foam.

  • release the umami nuances

  • turn the preparation into a small ritual

At Matcha Zen, we always maintain that preparing matcha is not just mixing water with a powder: it's about attending to a detail that attends to you. And the chasen is the tool that unlocks that experience.

The number of bristles on the chasen: why it matters (much more than it seems)

Here's one of the most poorly explained secrets in the world of matcha. If you've ever wondered why some whisks create more foam, others whisk thicker, and still others feel as smooth as a brush, the answer lies in the number of wires.

Chasen with 60–80 bristles (stiffer, traditional style)

  • Ideal for koicha , thick matcha.

  • Dense mix, little foam.

  • Recommended for those who follow more traditional ceremonies.

  • Perfect if you're looking for depth rather than foam.

Chasen with 80–100 bristles (the most balanced)

  • The “all-terrain” option.

  • They work wonderfully for usucha (standard matcha).

  • Fine foam, pleasant texture.

  • Great option for beginners and for everyday use.

Chasen with 100–120 bristles (more flexible and foamy)

  • Smooth whipping, more abundant foam.

  • Ideal for those looking for a creamy texture.

  • Very good for matcha latte style (although not essential).

Chasen with 120–160 bristles (professional premium level)

  • Extremely thin.

  • They generate a spectacular, soft and shiny microfoam.

  • Preferred by experts and lovers of "matcha-cloud".

  • They require a slightly more controlled shake.

Easy rule for choosing based on your goal:

  • More bristles → more foam

  • Fewer bristles → more control and density

If you're preparing 100% authentic ceremonial matcha, one with 80 to 100 bristles is perfect.
If you're looking for Instagram-worthy photos or super creamy lather, aim for 120 bristles or more .

How to use a chasen like a matcha master

Forget the circular shake. Matcha isn't stirred; it's awakened.

Steps for a perfect smoothie:

  1. Preheat the bowl and the chasen
    Pour hot water on and leave for a few seconds.
    Remove it and dry it.

  2. Sift the matcha
    1–2 grams is enough. The sieve prevents lumps and works wonders.

  3. Add hot water (70–80°C)
    Never boil it, or you'll ruin the flavor.

  4. Shake in the shape of a “W” or “M”
    Quick, firm, without fear.
    The goal is to incorporate air, not to make circles.

  5. For when you have fine foam
    Large bubbles should not be visible.
    Just one smooth, shiny, vibrant green coat.

When you do it right, the matcha almost seems to smile at you.

How to clean and properly maintain your chasen

The chasen is durable, yet delicate. The better you treat it, the more ceremonies it will accompany you through.

  • Wash it with water only. No soap.

  • Let it air dry.

  • If you have a chasen-kusenaoshi stand, even better.

  • Never store it damp.

  • Don't crush it or leave it inside the bowl.

With care, a chasen can last for months or even more than a year if you use it occasionally.

A journey to the past: the history of the chasen

The chasen has a history spanning over 700 years. It originated in Japan during the spread of Zen Buddhism. For monks, preparing matcha was a meditative act, a way to cultivate mindfulness in the present moment.

The chasen represented:

  • craft

  • harmony

  • nature

  • presence

Their manufacture remains entirely by hand. Traditional Japanese schools of artisans maintain techniques passed down from master to apprentice for centuries. Each chasen is unique; no two are alike.

This respect for craftsmanship connects directly with the Matcha Zen philosophy: small has power.

The role of the chasen in the tea ceremony

It's not just a tool. It's a symbol.

In the Japanese tea ceremony, the chasen represents:

  • purity

  • presence

  • dedication

  • beauty in simplicity

And its use creates the foam known as mochi , a symbol of perfection and harmony.
The whisking motion, smooth but determined, reflects the Zen attitude: light, focused, unhurried but steady.
