Matcha Scoop (Chashaku)
A chashaku is the slim bamboo scoop you see resting across the rim of a tea caddy. It looks decorative and it is, but it is also a measuring device with a surprisingly consistent capacity: one scoop is about one gram of matcha. That single number is why the tool survived five centuries essentially unchanged, and why every traditional matcha recipe is written in scoops rather than spoons.
The short answer
A chashaku holds roughly 1 gram of matcha per scoop, so usucha takes two scoops (2g) and koicha takes three to four (3–4g). A level teaspoon holds about 1.5g and a heaped one about 2.5g, which is why teaspoon measurements vary so much. Chashaku are carved from a single piece of bamboo, cost $5–40, and must never be washed with water.
What it is
A scoop carved from a single piece of bamboo, typically 18cm long and about 1cm wide, with a slight curve at the working end and a node (fushi) partway down the shaft. There is no bowl in the spoon sense — the curve is shallow and holds a small heap of powder rather than a measured volume.
Why it matters
Matcha doses are small and the difference between 2g and 3g is the difference between a balanced bowl and a bitter one. A chashaku gives you a repeatable unit without a scale, and unlike a metal spoon it does not conduct heat, does not scratch a lacquered caddy, and does not carry detergent residue into the powder.
What to look for
Single-piece bamboo construction
The whole scoop — handle, node and curve — should be carved from one continuous piece of bamboo, steam-bent at the tip. Two-part scoops with a glued or pinned head exist at the very cheap end and fail at the joint. You can usually see the grain running unbroken through the curve in a decent product photo.
Bamboo type
White bamboo (susudake) is the standard and the cheapest. Smoked bamboo (susutake, aged in farmhouse rafters for decades) is darker, denser and considerably more expensive. Black bamboo (kurodake) and purple (shichiku) are used for higher-end pieces. For measuring matcha, all of them perform identically — this is an aesthetic decision, not a functional one.
Node position
Traditional chashaku have the node roughly in the middle of the shaft. Nodeless scoops (a single smooth length) are a distinct and older style used in some schools. Node position affects nothing about how much matcha you scoop; it affects price and formality.
Curve depth
A shallow, even curve delivers a consistent scoop. Very flat scoops under-deliver and you end up taking three where two is written; overly deep ones are usually poorly steamed and crack along the bend within a year.
Finish quality
Run your eye along the edges in the photos. Clean, smooth cuts with no splinters or tool marks indicate hand-finishing. Rough edges catch powder and make the scoop harder to wipe clean.
Whether it comes with a tube
Higher-end chashaku ship in a bamboo tube (tsutsu), often signed and named by the maker. This is a collector's feature and adds significantly to the price. It protects the scoop in storage but has no bearing on daily use.
How long it lasts
Years to decades, provided it never gets wet. A chashaku has no moving parts and no consumable element — the only thing that kills one is water. Bamboo swells when wet and dries unevenly, which cracks the steam-bent curve and can grow mould inside the grain. A dry-wiped chashaku will outlast every other tool on your tray.
Brands and origins to know
Names you'll encounter while shopping. We don't sell any of these — this is a neutral overview of who makes what.
Takayama workshops
Takayama, Nara, Japan
The same bamboo district that makes chasen also produces most quality chashaku. Expect $20–40 for a clean, hand-finished white bamboo scoop.
Ippodo and Marukyu Koyamaen retail scoops
Kyoto, Japan
The Kyoto tea houses sell own-branded chashaku alongside their matcha. Reliable quality at $15–30 and a straightforward way to buy one you can trust.
Named artisan chashaku
Various, Japan
Carved and signed by a named maker, sometimes by a tea master, and sold in an inscribed tube. $100 to well over $1,000. Bought as objects, not as measuring tools.
Generic bamboo scoops
China, Taiwan
The $5 scoop included in almost every starter set. Function is fine — it measures a gram like any other. Edges are rougher and the curve is less even.
Care
- Never wash it. No water, no soap, no dishwasher. This is the single rule that matters.
- Wipe with a dry cloth or a dry paper towel after each use. Residual matcha oil is not a problem; moisture is.
- Store flat and dry, out of direct sunlight. Sun bleaches bamboo and dries out the bend.
- Keep it away from steam — resting it across a hot kettle or a fresh bowl will do slow damage.
- If it does get wet, dry it immediately with a cloth and leave it flat in still air for a day.
Common mistakes
- Washing it, which is how most chashaku die. Bamboo swells, dries unevenly, and cracks at the curve.
- Assuming one chashaku scoop equals one teaspoon. A scoop is about 1g; a heaped teaspoon is closer to 2.5g.
- Storing it in a drawer with wet utensils, where it absorbs ambient moisture.
- Using it to scoop from a tin you keep in the fridge without letting the tin come to room temperature — condensation gets on the bamboo.
- Buying an expensive signed piece for daily use. Everyday scooping does not benefit from it.

Frequently asked
How many grams is one chashaku scoop of matcha?
About 1 gram. The traditional measure is two scoops for usucha (thin matcha), which gives roughly 2g, and three to four scoops for koicha (thick matcha), giving 3–4g. Scoop capacity varies slightly with the depth of the curve, so if you are being precise, weigh two scoops once on a 0.1g scale and calibrate to your own chashaku.
How much is a chashaku compared to a teaspoon?
One chashaku scoop of about 1g is roughly two-thirds of a level teaspoon, which holds around 1.5g of matcha. A heaped teaspoon holds closer to 2.5g. This is why recipes written in teaspoons produce such variable results — the difference between a level and a heaped teaspoon is a full gram, enough to turn a balanced bowl bitter.
Can you wash a chashaku?
No. Water is the only thing that reliably destroys a chashaku. Bamboo absorbs moisture and swells, then dries unevenly and cracks along the steam-bent curve, and trapped moisture inside the grain can grow mould. Wipe it with a dry cloth after each use — matcha powder is dry and leaves no residue that needs washing off.
Do I need a chashaku or can I use a teaspoon?
A teaspoon works, but it is less consistent. The chashaku's advantage is a repeatable one-gram unit and the fact that bamboo carries no detergent residue and does not scratch a lacquered caddy. If you already own a 0.1g digital scale, that beats both for accuracy. If you do not, a chashaku is the cheapest way to get consistent doses.
What is a chashaku made of?
A single piece of bamboo, carved and steam-bent at the tip. White bamboo (susudake) is standard; smoked bamboo (susutake), black bamboo (kurodake) and purple bamboo (shichiku) are used for higher-end pieces. Some modern scoops are made from wood, metal or plastic, which function adequately but lack bamboo's neutrality and traditional association.
