Shizuoka Green Tea: How to Brew Sencha, Gyokuro & Genmaicha
Japan's green teas don't all taste alike, and the differences begin in the field and the steam room — not just the cup. This guide covers three Shizuoka green teas — deep-steamed sencha, shade-grown gyokuro, and toasted matcha genmaicha. You'll learn what makes each one distinct and exactly how to brew it — the water temperature, the amount of leaf, and the steeping time that let each tea show its best side.
All three come from Shizuoka, two of them from the hills of the Shimada–Yuhi district above the Ōi River. Here's how to tell them apart, and how to make each one well.
Why Shizuoka?
Shizuoka has been the heartland of Japanese tea for generations. The prefecture runs from coastal plains up into misty mountain valleys, and that spread of elevation and climate is why one region can produce everyday sencha, refined gyokuro, and much in between. More on Japan's tea regions →
Shizuoka has long been Japan's leading green-tea region and remains one of its two largest, alongside Kagoshima. It is especially known for high-grade first-flush leaf and for the wide range of tea styles grown across the prefecture.
Our sencha and the base for our genmaicha come from the Shimada–Yuhi district, upstream of the Ōi River, where a wide day-to-night temperature swing slows the leaf and concentrates its sweetness. Shimada also happens to be one of the towns credited with the birth of deep-steamed tea — which brings us to the first cup.
Fukamushi sencha: deep-steamed, everyday green
Every green tea is steamed soon after picking to stop the leaf from oxidizing. Fukamushi (深蒸し, "deep-steamed") simply means the leaf is steamed longer than usual.
Fukamushi sencha is steamed two to three times longer than ordinary sencha — roughly one to three minutes instead of 30–40 seconds. The extra steaming breaks the leaf into a finer cut, so it brews quickly into a cloudy, deep-green cup that is sweet and low in astringency. The style emerged in Shizuoka Prefecture in the 1960s, with several towns — Shimada among them — named in its origin. More on fukamushicha →
In the cup it's forgiving and fast: rounded, gently sweet, ready in about thirty seconds. Because the cut is fine, a kyusu with a good fine-mesh strainer matters — a coarse strainer lets too much sediment through.
How to brew: 4 g leaf · 70 °C (158 °F) · 180 ml · 30 seconds. Re-steep two or three times, shortening each infusion.
Gyokuro: shade-grown, slow and sweet
Gyokuro is the special-occasion tea of the three — grown differently, and brewed differently.
Gyokuro (玉露, "jade dew") is shaded from the sun for about twenty days before harvest. Deprived of light, the leaf holds onto the amino acid L-theanine instead of turning it into the catechins that make tea astringent — and the tongue reads that theanine as umami and sweetness. It is brewed cool, around 50–60 °C, in small volumes. More on gyokuro →
The result is a low, slow, almost broth-like cup: thick, mellow, and meant to be savored in a few small sips. The leaves re-steep generously, and the tender spent leaves are traditionally eaten with a dash of ponzu.
One honest note: this is Shizuoka gyokuro. Most of Japan's famous gyokuro comes from Yame in Fukuoka and Uji in Kyoto; Shizuoka gyokuro is its own thing, and we'd rather tell you where it's actually from than borrow another region's name.
How to brew: 4 g leaf · 50–60 °C (122–140 °F) · 60 ml · 2 minutes. Re-steep two or three times, raising the temperature slightly each round.
Matcha genmaicha: toasted rice and a lift of matcha
If gyokuro asks you to slow down, genmaicha is the opposite — the comfortable, all-day cup.
Genmaicha blends green tea with toasted brown rice; some grains puff like popcorn as they roast, which is where the tea's nutty, toasty aroma comes from. This one adds a dusting of bright matcha, which deepens the color and rounds out the flavor. Brewed hot and fast, it's warm, gentle, and low in bitterness — an easy place to start.
One clarification worth making: this is a leaf tea you steep, not a ceremonial matcha you whisk. The matcha here is a small blend-in, not a bowl of usucha.
How to brew: 4 g leaf · 90 °C (194 °F) · 180 ml · 30 seconds. Re-steep once or twice.
Brewing cheat-sheet
| Tea | Leaf | Water temp | Water | Time |
|---|---|---|---|---|
| Fukamushi sencha | 4 g | 70 °C / 158 °F | 180 ml | 30 sec |
| Gyokuro | 4 g | 50–60 °C / 122–140 °F | 60 ml | 2 min |
| Matcha genmaicha | 4 g | 90 °C / 194 °F | 180 ml | 30 sec |
The pattern to remember: the more delicate and umami-driven the tea, the cooler the water. Boiling water scorches sweet, shaded leaf; a gentler pour draws out sweetness instead of bitterness.
What to brew it in
A kyusu — a side-handle Japanese teapot with a built-in strainer — is the one tool that makes all three teas easier. Fukamushi sencha especially wants a fine mesh, because its fine leaf particles slip through a coarse strainer. For gyokuro, small cups and small pours suit its concentrated style.

FAQ
What is deep-steamed (fukamushi) sencha?
Fukamushi sencha is a Japanese green tea steamed two to three times longer than ordinary sencha — about one to three minutes instead of 30–40 seconds. The longer steam breaks the leaf into a finer cut, producing a cloudy, deep-green infusion that brews fast and tastes sweet and mild, with little astringency. The style developed in Shizuoka Prefecture in the 1960s.
What water temperature should I use for Japanese green tea?
It depends on the tea. Everyday sencha and genmaicha are brewed hot, around 70–90 °C. Shaded teas like gyokuro are brewed much cooler, around 50–60 °C, to draw out sweetness rather than bitterness. As a rule, the more delicate and umami-rich the leaf, the cooler the water — boiling water tends to scorch fine green tea.
What's the difference between gyokuro and sencha?
Both are Japanese green teas made by similar steaming methods, but sencha is grown in full sun while gyokuro is shaded for about twenty days before harvest. The shading raises the leaf's L-theanine, giving gyokuro more umami and sweetness and less astringency. Gyokuro is brewed cooler and in smaller volumes, and is generally more concentrated.
Is matcha genmaicha the same as matcha?
No. Matcha is finely ground green tea whisked into water and drunk whole. Genmaicha is a leaf tea — green tea blended with toasted brown rice — that you steep and strain. "Matcha genmaicha" simply adds a little matcha powder to the blend for color and flavor; it's still steeped like ordinary tea, not whisked.
Does Japanese green tea have caffeine?
Yes. Green tea naturally contains caffeine, and the amount varies by type and brewing. Shaded teas such as gyokuro tend to be higher in caffeine than everyday sencha, while genmaicha — cut with toasted rice — is usually on the lower side. Cooler, shorter infusions extract less caffeine than long, hot ones.
How should I store loose-leaf green tea?
Keep green tea sealed in an airtight container away from light, heat, moisture, and strong odors, which it absorbs easily. Reseal after each use and drink it within a month or two of opening for the freshest flavor and color. Green tea doesn't improve with age — fresher is better.
