The Chasen is the essential tool for making a Matcha. It is most often seen in the Japanese Tea Ceremony, but it is perfectly acceptable to use anytime you are brewing Matcha. After you have added Matcha to the cup, you move the Chasen evenly back and forth as if you are drawing the letter "M". Whisk until the tea is a frothy emerald green liquid.
