Chashaku is a traditional Japanese tea scoop used for measuring and pouring Matcha powder into the teacup. In this article, we’ll explore the importance of this tool and offer some tips on its maintenance.
What is a Chashaku?
Made of bamboo, the Chashaku is a small and narrow scoop that is about half the size of a teaspoon. It is an essential tool used in Japanese tea ceremony to ensure the perfect amount of Matcha powder is added to the teacup. However, if you’re just enjoying Matcha casually, a teaspoon can function just as effectively.

Maintenance of the Chashaku
A Chashaku is a delicate item that can easily stain due to moisture. To clean the tool, wipe off any remaining Matcha powder with a tissue or cloth. Avoid washing it with water as much as possible. Similar to a Chasen (bamboo whisk), it is best to store the Chashaku in a cool and dry place away from direct sunlight and high humidity. Dishwashers and dryers should also be avoided as sudden changes in temperature and heat can crack the bamboo.
How to use a Chashaku
Using the Chashaku is straightforward. One scoop of Matcha powder using a Chashaku amounts to roughly one gram. Therefore, for an Usucha preparation, you would need 2 scoops of Matcha powder for 70 ml of water. For a Koicha preparation, you would need 4 scoops of Matcha powder for 30 ml of water.
The Importance of Chashaku
While a Chashaku may not be as essential as other tea tools such as the Chasen or Kyusu, it certainly adds to the overall Matcha experience. A quality Chashaku will come with a pleasant and elegant scent of a young bamboo, which complements the Matcha experience.
In conclusion, the Chashaku is an important tool for those practicing Japanese tea ceremony or those who simply enjoy Matcha tea. Proper maintenance of the Chashaku is crucial to ensure its longevity and to preserve its quality. With these tips in mind, you can enjoy a perfect cup of Matcha tea every time.
