The Chasen, Evolving
In our last article, we traced the chasen back to its origins from a small village in Nara to the tea rooms of Japan and explored the rituals and reverence that have surrounded this tool for over 500 years.
But the chasen’s story does not end there. Today, it is changing.
For 500 years, the chasen looked more or less the same. Recently, that has begun to change.
As matcha has found new audiences around the world, new variations of the chasen have emerged to meet different needs and lifestyles. Some are practical innovations; others are quietly radical reinterpretations of a centuries-old form.
Silicone chasen is a particularly practical option for matcha lattes and milk-based drinks. Unlike bamboo, silicone can be thoroughly washed with soap and hot water, making it easier to manage the residue from milk, syrups, or other ingredients without risk of cross-contamination or deterioration.
Electric chasen do the whisking at the press of a button, making matcha more accessible for those with limited hand mobility or simply less time.
Mug-sized chasen are designed for the proportions of a Western mug rather than a traditional tea bowl, meeting people where they already are in their kitchens.
Automated matcha machines handle the entire process from powder to cup, increasingly common in both cafés and home settings.
And then there is this: Suikaen (翠華園), one of Takayama’s oldest and most respected chasen workshops, recently began attaching small, flower-shaped charms to their whisks. The gesture is deliberate. Their message to customers is simple: matcha is for everyone, and the chasen should feel like a welcome part of daily life, not an intimidating object reserved for formal occasions.
There are paper chasens that are perhaps the most unexpected innovation of all. Compared to bamboo, which requires careful maintenance and proper drying conditions, the paper chasen is remarkably low-effort. The intention behind it mirrors that of Suikaen’s flower-charm whisk: matcha should be something anyone can enjoy, any day, without ceremony or fuss.
Tradition does not have to mean rigidity. These evolutions are honest responses to real needs, and in many ways they carry the same spirit as the original craft: bringing good matcha to more people.
A Tool the World Is Watching
Born from a single stalk of bamboo. Shaped by hands that took a decade to learn their craft. Used with care and intention in the tea ceremony. And when its work is finally done, honored with a ritual farewell. That is the chasen in its truest form.
And now, this same tool has found its way onto café counters around the world. Carried by the wave of the global matcha boom, the chasen is being seen by more people than ever before in its 500-year history. For many in the tea world, this is something they genuinely hoped for. The chasen, and the culture it represents, reaching new hands and new places.
Yet the spread has exceeded what most could have imagined. And here is a quiet irony: while matcha culture has exploded globally, interest in the tea ceremony within Japan itself has not grown at the same pace. The chasen is becoming more visible abroad even as the tradition it comes from faces its own quiet challenges at home.
And slowly, a question has begun to take shape. As the chasen travels further from its origins, what becomes of the spirit it was made to carry? Is this really how things should go?
In 2025, a video posted by an American matcha startup went viral for all the wrong reasons. The founder, making the case for his product, called traditional matcha tools unnecessary clutter and swept a chasen and tea bowl from a table with his arm. A tool that practitioners handle with quiet reverence had been called garbage, on camera, for the world to see.
The chasen is spreading across the world. But that does not mean it is being understood, or cared for, in the way it deserves. These two things are not the same, and they are not happening together.
So what is actually going on in cafés around the world? And how should we think about it? That is the conversation for the next article.
