When most people picture Japanese matcha, they picture Kyoto.
Uji's ancient tea fields, the temples, the mist rising off the river — that image has dominated the global conversation about Japanese tea for good reason. Uji is extraordinary. But Japan's largest tea-producing region is not Kyoto. It is Kagoshima, and what it produces — particularly in that narrow, critical window of the first flush harvest — deserves to be understood on its own terms.
MP-01 comes from Kagoshima, Kyushu. This is its story.
The Geography of Kagoshima
Kagoshima sits at the southern tip of Kyushu, Japan's southernmost main island. To the south, the sea. To the north and east, mountain ranges. And beneath much of the agricultural land, the legacy of one of Japan's most active volcanic regions.
The prefecture is dominated by Sakurajima — an active volcano that has been erupting continuously, in varying degrees of intensity, for over a century. Its ash drifts across the region regularly enough that locals keep umbrellas not just for rain. The volcanic activity that makes Sakurajima an inconvenience for daily life has, over millennia, created something exceptional for agriculture: soils rich in minerals, well-drained, and deeply fertile.
Tea plants grown in these soils absorb a mineral profile that is distinctly Kagoshima. The result is a leaf — and ultimately a matcha — with a bold, full-bodied character that reflects the land it comes from.
Why Kagoshima Became Japan's Largest Tea Producer
Kagoshima overtook Shizuoka as Japan's leading producer of aracha (crude, unfinished tea) in 2024 — a milestone that reflects decades of investment, modernization, and geographic advantage.
The prefecture's warm climate means that tea plants here emerge from dormancy earlier in the year than almost anywhere else in Japan. The first flush harvest in Kagoshima often begins in early to mid April, weeks ahead of cooler regions further north. This early start gives Kagoshima matcha a distinctive spring energy — leaves harvested at the precise peak of the plant's annual output.
That same warmth creates a pronounced swing between daytime highs and nighttime lows in early spring. This temperature differential is not incidental — it concentrates the leaf's sugars and amino acids, adding sweetness and depth to what might otherwise be a straightforward, high-volume crop. Kagoshima's climate, in other words, does not simply produce more tea. It produces tea with a specific character that cannot be fully replicated in a warmer, more uniform climate.
The Cultivars Behind MP-01
A matcha's cultivar — the specific variety of Camellia sinensis used — shapes its flavor as fundamentally as its origin. MP-01 is produced from a blend of six cultivars, each selected for what it contributes to the overall profile.
Yutakamidori is Kagoshima's signature cultivar and the most widely planted in the prefecture. It produces leaves with high amino acid content, contributing to the bold umami that defines MP-01's opening note. It also responds exceptionally well to shade-growing, retaining sweetness even under extended cover.
Saemidori adds brightness and a clean, almost floral sweetness. Originally developed by crossing Yabukita with Asatsuyu, Saemidori is prized for its vivid green color and the clarity it brings to a blend.
Yabukita is Japan's most widely planted tea cultivar — accounting for roughly 70% of all tea grown in the country. Its ubiquity reflects its reliability: consistent, balanced, with a mild umami that anchors a blend without dominating it.
Asanoka is less common but valued for its aroma and the way it rounds out sharper edges in a multi-cultivar blend. It contributes to the pleasant, lingering aftertaste that MP-01 is known for.
Kanayamidori brings body and a slightly earthy depth. Developed in Shizuoka but well-suited to Kagoshima's soils, it adds weight to the blend.
Okumidori is a late-budding cultivar that produces leaves of exceptional quality during the first flush. Its delayed emergence relative to other cultivars means it benefits from slightly more of the spring warmth before harvest, adding richness and sweetness.
These six cultivars are blended with intention — each contributing something the others do not, producing a matcha that is more complex than any single cultivar could achieve alone.
The Character of Kagoshima Matcha
MP-01 does not whisper. It announces itself.
The first thing you notice is the umami — rich, full, immediate. This is Yutakamidori's signature, amplified by the mineral intensity of Kagoshima's volcanic soils. The bitterness that follows is not harsh. It is balanced, structured — the kind of bitterness that frames the sweetness rather than overwhelming it, and that leaves a clean, pleasantly dry finish on the palate.
Straight in a warmed chawan, MP-01 is a matcha that rewards full attention. As a latte, it holds up against steamed milk in a way that many more delicate matchas do not — the intensity of the flavor pushes through rather than being diluted.
This is intentional. We sourced from Kagoshima specifically because we wanted a matcha with presence. Something that makes an impression. Something that is immediately, unmistakably good.
Stone-Milled to Order — Why Freshness Changes Everything in Kagoshima Matcha
Matcha begins to oxidize from the moment it is ground. The volatile aromatic compounds that give freshly milled matcha its brightness and character are, within weeks of milling, noticeably diminished. Within months, they are largely gone — leaving behind a flat, sometimes yellowish powder that bears little resemblance to what left the stone mill.
Most matcha you encounter in stores was milled months before it reached you. Sometimes longer.
MP-01 is milled to order. When you place your order, that is when the milling begins. The tin you receive was sealed within days of grinding. The difference — in color, in aroma, in the complexity of the first sip — is not subtle.
Kagoshima's bold cultivars and volcanic mineral profile are not lost in transit when the matcha is this fresh. They arrive intact.
A Region in Transition
Kagoshima's rise to prominence in Japanese tea has not been without tension. As production has scaled, questions about quality, sustainability, and the succession of aging farmers have become increasingly urgent throughout the region. Many tea fields in Kyushu, as across Japan, face the challenge of aging producers with fewer young people willing to continue the work.
The producers who supply our matcha understand this. Their commitment to first flush only, to traditional shade-growing, and to stone milling is not simply a quality decision — it is a statement about what they believe Japanese tea should remain, even as the industry around them changes.
We source from Kagoshima because of what these producers make. We talk about it openly because we believe the people behind the matcha matter as much as the matcha itself.
