About the Chasen

Here's how to properly prepare your chasen (matcha whisk) before first use.

Before using your chasen for the first time, you should untangle it to loosen the fine bamboo bristles and allow it to swing freely when whisked. This will result in a creamy, fine-textured matcha foam.

1. Pour warm water into a bowl: Fill a matcha bowl or cup with warm (not boiling) water (approx. 70-80°C).

2. Soak the chasen for 10-15 minutes: Place the chasen completely in the water with the bristles facing down (the handle should remain dry). Let it soak for at least 10-15 minutes.

3. Bristles loosen: Soaking softens the bristles, allowing them to open slightly and assume their typical curved shape.

4. Gently shake: Remove the chasen from the water and shake it lightly over the bowl. Then you can begin preparing your matcha.

How to properly care for your chasen

Before preparation

Soak in warm water: Immerse the bristles of your chasen in approximately 70–80 °C warm water for 1–2 minutes.
This makes the bamboo soft and flexible, preventing it from breaking when struck.

Soaking helps the chasen retain its natural curved shape → for extra creamy foam.

After preparation

Clean with water only: Rinse the chasen with warm water immediately after use. Do not use dish soap, as this dries out the bamboo and can leave residue.

Shake gently: Carefully remove excess water without bending the bristles.

To dry properly: Place the chasen with the bristles facing upwards or on a chasen holder (kusenaoshi), so that it dries evenly and retains its shape.

Store in a well-ventilated place: Keep it in a dry, well-ventilated area. Do not store in closed containers, as this can lead to mold.
