The Tea Industry Word That's Been Hiding in Plain Sight

What's going on

Every spring in Japan, the tea world enters its most anticipated stretch of the year: shincha season. Shincha — the year's first tea harvest — is prized for its freshness, sweetness, and vivid color. Think of it as the Beaujolais Nouveau of the tea calendar, an occasion that serious tea lovers look forward to for months.

A tea shop shared a photo of freshly brewed shincha and invited followers to admire its clarity and suishoku. The word they used, written as 水色, is a standard term in the tea trade — it refers to the color of the brewed liquid itself. But most Japanese readers don't work in the tea industry. To them, those two characters have one obvious reading: mizuiro, meaning light blue.

The replies arrived swiftly. Most were some variation of "that tea looks green to me." A few readers quietly began to wonder if something had gone wrong with their vision. The shop's follow-up clarification set things straight — and sent a lot of people to reconsider a word they'd technically seen many times before.

Look!! This crystal-clear suishoku. Shincha season only comes once a year — live to a hundred and you get it a hundred times at most. Drink it, taste it, let it move you.

見て‼︎この澄んで濁りのない水色。100年生きても100回しか経験できない新茶シーズン。飲んで味わい心を動かし楽しんだもの勝ちです。

Our shincha is coming in little by little — come experience flavors that only exist this year.

少しずつ新茶が仕上がってきてますので2026年しか味わえない旬の香味を体験してみてください。

Looks green to me

緑茶色に見える

Ok I’m having a minor crisis — am I colorblind? Because that tea looks completely green to me, not blue at all

ちょっと今自分が色盲になってる可能性出てきて頭の震えが止まらないんですが、このお茶って水色なんでしょうか？私には緑茶色に見えてるんですが

Didn’t expect so many people to see this post, and we’ve been getting a lot of questions about the word 水色. In the tea industry, it’s read as suishoku, not mizuiro — it refers to the color of the brewed liquid. We use it so naturally that it took someone pointing it out to make us realize: yeah, that’s not obvious at all‼︎

思いがけず多くの方にご覧いただき、「水色」という表現についてさまざまなお声をいただきました。茶業界では「水色」は「みずいろ」ではなく「すいしょく」と読み、抽出したお茶の液体の色を表す言葉として使われています。当たり前に使っていたけど言っていただき確かにな‼︎と思いました。

The word 水色 has two completely separate lives in Japanese. In everyday usage it’s read mizuiro, meaning a soft sky-blue color. In the tea world — and across other beverage trades including black tea and Chinese tea — the same characters are read suishoku, simply meaning “the color of the brewed liquid.” Same kanji, same written form, different reading, different meaning.

What a beautiful word

綺麗な言葉だな

Oh thank goodness, what a relief — I’d been quietly worrying I might be going colorblind from staring at my phone too much 😅

なるほど早とちりで安心しましたケータイの見過ぎで視力が落ちたりしたので「そろそろ色盲かな？」と常々不安になってた物で

Finally, the suishoku mystery from Kemono Tea Time (a manga series about tea) is solved

やっと、けものティータイムの水色の謎がとけた

I only knew suishoku from Kemono Tea Time — honestly if I hadn’t read that, this post would’ve made zero sense to me. Why such a confusing name!!

水色(すいしょく)はけものティータイムで知ったな知らんかった意味わからんと思うなんでこんなややこしい名前になったんだよ！

Oh wow — I went to a tea specialty shop as a teenager, saw 水色 on the menu, and just… accepted it without understanding. Until now.

なるほど 10代の頃に行ったお茶専門店で、メニューに書いてあった「水色」の意味が、ようやくわかった

Exactly, people who know their tea say suishoku! Since it’s written the same as mizuiro, it gets confusing the moment it’s put in writing 🤔

そうそう、お茶に詳しい方は「すいしょく」と言います！漢字は「みずいろ」と同じ「水色」なので文字にするとややこしいですね〜🤔

I ran the original post through Grok and it translated 水色 as “liquor” — actually pretty accurate, I’m impressed (“Liquor” is the standard English term in professional tea tasting for the color and clarity of brewed tea.)

元投稿をgrokに翻訳してもらったらちゃんと水色をliquorにしてて感心した

It’s like how musicians read 音色 (timbre) as onshoku instead of the everyday neiro — same kind of specialist reading hiding inside familiar characters

作曲、演奏の人達が「音色」を「おんしょく」って読むのと一緒だな、なんか親近感

Yeah, exactly the onshoku vs neiro situation for 音色. Anyone making music with synths or a DAW goes with onshoku ☺️

音色を「おんしょく」と読むか「ねいろ」と読むかのような話ですね。シンセサイザーやPCで曲作る人間は前者☺️

Huh, so suishoku just… doesn’t land outside tea circles…

そっか、お茶界隈じゃないと水色(すいしょく)って通じにくいのか…

Ah right, suishoku is used in the black tea world too. Makes sense it’d be the same for green tea

あー、紅茶でも水色（すいしょく）使うな。当然緑茶もそうか

This is really educational. Is suishoku used for all types of sencha? (Sencha is leaf tea brewed with hot water, as distinct from powdered matcha.) Does it apply to matcha in the tea ceremony as well?

勉強になります。すいしょくは煎茶全般に使うもの？茶道のお抹茶にも使えるのでしょうか。

Worth knowing — suishoku isn’t just a Japanese tea thing, it’s used for black tea and Chinese tea too. Good word to add to your vocabulary.

「水色（すいしょく）」は茶をいれた時の色のことで日本茶に限らず紅茶や中国茶でも使われるから、知らんかった人は覚えておくといいやね。

When you think about it, you really do only ever hear suishoku in tea contexts — no wonder people outside that world have never come across it

確かに水色(すいしょく)はお茶関連でしか聞いた事ないし、知らん人は知らんよな…

I’ve always naturally read it as suishoku for brewed tea… but I genuinely can’t remember when I learned to separate that from mizuiro

緑茶も紅茶も入れた液体の色のこと「すいしょく」と普通に読んでたけど、私は「みずいろ」といつから区別してたのかな？

At this point it’s full occupational hazard — I see 水色 and instantly read suishoku, and I once tried to caption a lake photo as “beautiful mizuiro” and completely blanked on how to write it in kanji. I know that sounds made up. It isn’t.

もはや職業病で「水色」と見た瞬間「すいしょく」と読んでしまう上、湖の写真をアップしようとして「綺麗なみずいろ…あれ…？みずいろって漢字でどう書くんだっけ…？」って状態になったことがある…。嘘くさいけどほんとに。

Genuinely one of those things I’m glad I stumbled across

ホント、こういうの勉強になるー。

Had no idea!! Makes you wonder how many other specialized terms are hiding in plain sight like this

これは知らんかった！！まだまだ一般に知られてない業界用語とかあるんだろうな

I’m a little embarrassed to admit I didn’t know this until now. As someone from Shizuoka (one of Japan’s foremost tea-producing prefectures) of all people, I feel like I should have known. Will be keeping suishoku in mind from now on. Thank you for this.

「水色(すいしょく)」恥ずかしながら初めて知りました。お茶の名産地静岡県の県民としても、しっかりと覚えておきたい緑茶の表現だと思いました。大変参考になるお話ありがとうございました。

My take

The color really is something to look at. Matcha gets all the global attention these days, but there's something quieter and more grounding about a cup of sencha — just hot water and leaves, doing exactly what they've always done.
