Saikaien Tokusen 100g

I recently picked up a 100g bag of Saikaien Tokusen from Waso UK. Honestly, I had never heard of Saikaien before Waso started importing them, but tasting this tea for the first time has been an absolute revelation. If you are used to standard supermarket exports or even high-grade Shizuoka sencha, this is going to catch you completely off guard. It is heavy, rich, and intensely flavourful.

After digging into the facts and thoroughly testing my first few cups, I am genuinely blown away by the unique regional processing happening here.

The "magatama" secret:

When you open the bag, the dry leaves look unusual. Standard sencha is rolled into tight, straight pine needles. The Saikaien Tokusen leaves are curly, twisted, and shaped a bit like small commas.

This is because it is a Tamaryokucha (curly green tea). It is the regional speciality of the Sonogi area in Nagasaki Prefecture. During processing, the producers skip the final straightening step. This seemingly minor visual difference is crucial because those curled magatama shapes trap the natural oils and aromas differently, allowing the tea to release its flavour in an immediate, explosive burst the second the hot water hits it.

Heavy, soupy, and deep-steamed:

Right from the first pour, this tea behaves exactly like a premium fukamushi (deep-steamed) green tea. The resulting liquid is a vibrant, opaque, neon yellowish-green.

Because the heavy steaming process breaks down the leaf structure, microscopic leaf particles are suspended directly in the water rather than just infusing it. You are left with a thick, almost colloidal texture that actively coats your tongue. It feels soupy and heavy in the best possible way. The wet leaves in the strainer is broken up and mushy, which is the visual proof of that heavy steaming breaking down the cell walls to release maximum umami.

Tasting notes and sweet chestnut:

The flavour profile is exceptionally strong and deeply savoury. It hits you with an initial wave of green tea grassiness, but then it transitions into something entirely different.

The Broth: Due to use of the Saemidori cultivar, the brew is incredibly high in amino acids. It has a savoury, broth-like punch with virtually zero astringency.

The Roast: The finish brings distinct roasted notes and a lingering, sweet chestnut aroma.

That sweet chestnut element comes from the Hi-ire (final firing) process. Producers in Kyushu often fire their teas at slightly higher temperatures, caramelising the sugars on the leaf surface. The curled tamaryokucha shape locks in that toasty finish, giving you the dense body of a deep-steamed tea combined with the aroma of a roasted tea.

The Saikaien pedigree:

It turns out Saikaien is a massive heavyweight in the Japanese domestic market. They are consistent winners at the Nihoncha Award (Japan Tea Awards), often taking top honours for their mastery of the notoriously difficult Saemidori cultivar.

Sonogi tea accounts for roughly 1% of total Japanese tea production. It is a rare, boutique regional style that rarely makes it out of the country without being blended into generic export batches. The packaging itself confirms its pedigree. It bears the official "Nagasaki Prefecture Recommended" seal alongside bold calligraphy reading fukuyokana (a plump, rich flavour) and the gold Tokusen (Special Selection) badge.

I also have an unopened bag of their £19 award-winning Tamasui waiting for me.
