What Is Matcha? A Beginner’s Guide for Tokyo Travelers

You’re going to see the word matcha roughly four hundred times a day in Tokyo — on lattes, gelato, crepes, KitKats, and an entire green-tinted section of every souvenir shop. Before you spend your trip drinking it, it’s worth thirty seconds knowing what it actually is. It makes everything taste more interesting.

The short answer

Matcha is powdered green tea — but not just any green tea ground up. It’s made from tencha: tea leaves that are shade-grown for weeks before harvest, then steamed, dried, stripped of stems, and stone-milled into an ultrafine powder.

The crucial difference from every other tea: you don’t steep matcha and throw the leaves away. You whisk the powder into water and drink the entire leaf. That’s why matcha tastes stronger, hits differently, and costs more than a teabag ever will.

Why shade-growing matters

Covering the tea plants before harvest slows photosynthesis. The plant responds by producing more chlorophyll — that electric green color — and more of the amino acids that give matcha its signature umami: the savory, almost brothy depth underneath the bitterness. Sun-grown tea can’t fake this. If you’ve had “matcha” that tasted like grass clippings and regret, it probably wasn’t shade-grown tencha.

What does it taste like?

Real matcha is a stack of flavors in this order: vegetal green → savory umami → a clean bitterness → a sweet aftertaste that shows up a few seconds late. Milk mutes the bitterness and amplifies the sweetness, which is why the matcha latte conquered the world. Fruit does something even more interesting — the contrast trick we break down in our fruit matcha guide.

Usucha vs koicha (thin vs thick)

Traditional matcha comes two ways:

  • Usucha (“thin tea”) — matcha whisked briskly with more water into a light foam. Bright, fresh, approachable. This is the standard way to drink it, and what most café matcha is based on.
  • Koicha (“thick tea”) — roughly double the matcha and half the water, kneaded rather than whisked into something dense and almost syrupy. Intense, ceremonial, and only made with high-grade matcha. In Asakusa you can try the koicha style at specialist shops like Kaminari Issa.

Start with usucha or a latte. Graduate to koicha when you’re ready to meet matcha with its makeup off.

Does matcha have caffeine?

Yes — matcha is green tea, and because you consume the whole leaf, it delivers a solid, steady lift. Most people find it gentler and less spiky than coffee. If you’re jet-lagged, treat an afternoon matcha the way you’d treat an afternoon espresso and time it accordingly.

“Ceremonial grade” — a quick reality check

Here’s a secret the souvenir shops won’t volunteer: “ceremonial” and “culinary” are not official, regulated grades in Japan. They’re marketing shorthand invented for overseas buyers. Real quality comes from the harvest timing, the shading, the milling, and the region. The practical takeaway for a traveler: judge matcha by taste and color (vivid green, not olive), not by the fanciest word on the tin.

The best ways to try real matcha in Tokyo

Asakusa happens to be one of the densest matcha neighborhoods in the city. A quick starter path, easiest to hardest:

  1. Fruit matcha or a matcha latte — the friendliest entry point. See the best matcha latte in Asakusa (full disclosure: our own stand WOW!CHA is on that list, fruit matcha is our specialty).
  2. Matcha desserts — gelato, tiramisu, crepes: the 10 best near Senso-ji.
  3. A straight bowl of usucha — whisked in front of you at a specialist like Uji no Kura.
  4. Koicha — the deep end. You’ll know when you’re ready.
