Isecha is the collective name for tea grown in Mie Prefecture. The northern districts around Yokkaichi, Suzuka, Kameyama and Inabe make mainly kabusecha, while the central and southern districts around Matsusaka, Watarai, Odai, Tsu and Taki make deep-steamed sencha.

Tea shaded for roughly one to two weeks before picking. Blocking the light raises the umami compounds and holds back astringency, giving a rounder cup. Gyokuro is shaded for about twenty days, and tencha, the leaf ground into matcha, is shaded and then dried without rolling.

Can tea grown in Mie be sold as Uji tea?

Yes. Under the definition set by the Kyoto Prefectural Tea Industry Council in 2004, Uji tea may use leaf from Kyoto, Nara, Shiga or Mie, refined by a Kyoto company inside Kyoto, with Kyoto-grown leaf given priority. The proportions are not disclosed.

Ise Tea, Mie: The Biggest Tea Region You Have Never Heard Of

Q: How big is Mie as a tea producer?

Third in Japan for both area and production. In 2023 Mie had 2,590 hectares under tea and produced 5,220 tonnes of crude tea, behind Shizuoka and Kagoshima. Its planted area is about a fifth of Shizuoka's.

Q: Which prefecture produces the most gyokuro?

Mie, at 74 percent of national production according to the Ministry of Agriculture. Mie also produces 63 percent of Japan's kabusecha, the largest share of any prefecture.

Third in Japan, first in shaded tea, and absent from almost every conversation about it.

This is the sixth and last of these pages, and it goes back to the first. When I looked at Uji, the thing that surprised me was the definition: Uji tea may be grown in four prefectures, not one, and the proportions are not published. Mie is one of those four. It also produces 74 percent of Japan’s gyokuro and 63 percent of its kabusecha, and I have not once seen its name on a tin abroad while building the Matcha Atlas.

Third in the country

2023	Area	Crude tea
Shizuoka	13,300 ha	27,200 t
Kagoshima	8,140 ha	26,100 t
Mie	2,590 ha	5,220 t

Ministry of Agriculture, Forestry and Fisheries, 2023.

Third in both, on a fifth of Shizuoka’s land. The Ministry of Agriculture’s own guide to traditional Japanese foods puts it plainly: Mie is third in Japan for area and production, and first for kabusecha, and it is the shaded tea that defines the region.

Narrow it to the shaded categories and the picture changes completely.

Mie’s national share
Gyokuro	74%
Kabusecha	63%

MAFF, leading prefectures by tea type, November 2024.

Three quarters of the gyokuro made in Japan comes from a prefecture most drinkers abroad could not place on a map.

Two halves of one prefecture

Mie runs long and narrow between mountains and sea, and its tea splits into two areas that make different things.

Area	Where	What
Hokusei (north)	Yokkaichi, Suzuka, Kameyama, Inabe	Kabusecha — bright green, round in the mouth
Chunansei (centre and south)	Matsusaka, Watarai, Odai, Tsu, Taki	Deep-steamed sencha — aromatic, firmer astringency

MAFF, guide to traditional Japanese foods.

The northern fields sit on flat volcanic-ash soil at the foot of the Suzuka mountains, and the prefecture notes that holdings there have been consolidating into larger units. That is the same combination — level ground, scale, machinery — that has taken Kagoshima to the top of the national table. Mie has been doing it quietly for longer.

Why nobody talks about it

Three things, and none of them is quality.

It picks late. Mie’s first flush runs from late April into mid-May, which the prefecture itself describes as a late-season region. Kagoshima’s first tea of the year arrives at the end of March. By the time Mie is picking, the story about new tea has already been told.

It grew up selling through other people. The prefecture’s own account is direct about this: Ise tea was sold widely in Kyoto, Osaka and Edo by merchants from Mie, and from the end of the Edo period it was pushed hard into export, where it earned foreign currency for the country. That is eight hundred years of tea and a long habit of reaching the drinker under somebody else’s name.

And its speciality is a leaf that gets blended. Shaded tea is bought by finishers and blenders more than it is sold in single-origin packets. Which brings us back to where this series started.

The line in the Uji definition

The definition the Kyoto Prefectural Tea Industry Council settled on in 2004 says that Uji tea may be made from leaf grown in Kyoto, Nara, Shiga or Mie, provided a Kyoto company refines it inside Kyoto, with Kyoto-grown leaf given priority. The council has said the actual proportions cannot be published.

I am going to stop there, because that is where the evidence stops. I cannot tell you how much Uji tea contains Mie leaf, and neither can anyone else outside the trade. What I can tell you is that Mie is named in the definition, that it makes three quarters of Japan’s gyokuro, and that these two facts sit next to each other in the public record.

Nothing here is hidden. Kyoto published the definition; the ministry published the shares. The definition exists precisely because there was not enough Kyoto-grown leaf to meet the stricter rule that was tried in 2003. The system is doing what it was designed to do. It is simply that the design is not what the name suggests to someone reading a tin in London or New York.

What shading actually is

Six regions in, the one technique that has come up in every single one is covering the field. It is worth setting the categories side by side, because the difference between them is mostly a number of days.

Tea	Shaded for	Then
Kabusecha	about 1–2 weeks	Steamed and rolled
Gyokuro	about 20 days	Steamed and rolled
Tencha	weeks, under frames	Steamed, dried without rolling, then stone-milled into matcha

Shading periods: Mie Brand (kabusecha); JA Fukuoka Yame (gyokuro).

Blocking light stops the leaf converting its amino acids into the compounds that taste astringent. More shade means more sweetness and umami, less bite, and a deeper green. Everything else — whether the leaf is rolled, whether it is ground — comes after that decision.

NOTE FROM JAPAN

かぶせ茶

KABUSECHA

covered tea

Kabusecha sits between sencha and gyokuro and has no established English name, which is part of why it travels badly. It is shaded, but not for long enough to be gyokuro; rolled, so it is not tencha. Mie makes most of Japan’s supply.

FROM YUKIIf you have found gyokuro too heavy and sencha too sharp, this is the one to try. It is also, in my experience, much easier to brew well than gyokuro.

What this means when you buy

Ise-cha means Mie. It is a registered regional trademark, so the name is protected — it is simply not famous. That is a different problem from Mori, which has no registration at all.

If you like gyokuro, you have probably been drinking Mie tea. Three quarters of it is made here, whatever the packet says.

Kabusecha is worth asking for by name. Most of Japan’s supply comes from one prefecture, and outside Japan it is rarely stocked. If a shop has it, that shop is buying with some care.

What I take from six regions

I started this series thinking a place name on Japanese tea was a rough guarantee of origin. It is not. It is six different kinds of promise, written by six different groups of people, mostly within the last hundred years.

Name	What it actually promises
Uji	Finished in Kyoto. Leaf may come from four prefectures
Nishio no Matcha	Grown, processed and stone-milled in two cities
Mori no Cha	Nothing — there is no registration
Yame Dento Hon Gyokuro	A written method, protected nationally
Chirancha	One city, under one name since 2017
Ise-cha	Mie. Registered, and largely unheard of

None of these names is lying. Each is answering a question that mattered to the people who wrote it, at the moment they wrote it. The trouble only starts when a reader assumes all six are answering the same question.

So the useful habit is not to memorise the map. It is to ask what the name on the tin was written to guarantee. Sometimes it is a field. Sometimes it is a factory. Sometimes it is a set of rules about straw and hand-picking. And sometimes, as here, the most important region is the one that never got its name onto the label at all.
