The chasen: everything you need to know about the matcha whisk
Partager
There's something almost meditative about the whisking motion. One hundred bamboo prongs, a Z-shaped movement, and the powder turns into foam. The chasen isn't just a tool — it's the heart of the ritual.
The chasen is the traditional whisk used for centuries to prepare matcha. Carved from a single piece of bamboo, it creates the emulsion that makes matcha smooth, frothy, and lump-free. No other tool truly replaces it.
What is a chasen?
A chasen is a bamboo whisk composed of many fine prongs (between 72 and 120 depending on the model) carved from a single piece of bamboo. This artisanal manufacturing dates back to the 15th century in the Takayama region of Nara Prefecture.
Each chasen is handcrafted. A good chasen produces a fine and stable foam in 20 to 30 seconds.
How many prongs: 72, 80, 100, 120?
- 72 prongs (Araho) — classic, sturdy. Ideal for beginners.
- 80 prongs (Kazuho) — good balance of sturdiness/fine foam.
- 100 prongs (Hyakuhondate) — very fine foam, recommended for usucha.
- 120 prongs and more — for connoisseurs. More fragile.
For everyday use, an 80-100 prong chasen is perfect.
Did you know?
The city of Takayama produces over 90% of the world's chasens. Artisans have passed down their technique since the 15th century, involving over 70 steps for a single whisk.
How to use the chasen
The movement: A quick Z or W motion, from right to left, scraping the bottom of the bowl. This movement creates a uniform emulsion and incorporates air for the foam.
Duration: 20 to 30 seconds for an usucha. The foam should be fine, persistent, and homogeneous.
Tip: Keep the chasen almost vertical, with the prongs well immersed. Dip it gently to avoid splashing.
Maintenance and lifespan
Before: Soak the prongs for 1-2 minutes in hot water to soften them. This prevents dry bamboo from breaking.
After: Rinse immediately with clear water. Never use soap. Air dry on a whisk holder to maintain its shape.
Lifespan: 2 to 6 months depending on frequency of use. When the prongs break or spread out, replace it.
Chasen or electric whisk?
An electric whisk is a good alternative for rushed mornings or cold lattes. But for a plain bowl of matcha, nothing replaces the chasen: the texture obtained is finer, more integrated. And the gesture is part of the ritual.
Frequently Asked Questions
Can the chasen be put in the dishwasher?
