As the plane drops toward Kagoshima Airport, the landscape tilts into view — tea fields, dozens of them, pressed into the hillsides in vivid green rows. One of those fields belongs to the Arimura family. A few hundred meters from the runway, three generations are out in the rows, working the same land their grandfather cleared seventy years ago.
Kirishima sits at the foot of Mount Takachiho, the peak where, according to myth, the gods first descended to earth. The name itself means "island in a sea of fog." Not a metaphor. Every morning, the fog rolls in and pools across the valleys, wetting the tea leaves with a moisture the sun will slowly burn away.
This is the Kagoshima tea farm we keep coming back to — not for its trophies, though there are plenty, but for what we taste in the cup.
An island in a sea of fog
When most people think of Kagoshima tea, they think of Minamikyushu City — vast flatlands, mild winters, early harvests that fetch premium prices at market. Kirishima is a different world entirely.
The climate here is cool. Severe temperature swings between day and night. Mornings and evenings wrapped in fog that filters the sunlight and feeds moisture to young shoots — a natural shading that no canopy could replicate. The tea that grows here carries a fragrance that lowland fields rarely produce.
From the road above the Arimura fields, I could see the fog sitting in the valley below like water in a basin. By midmorning it had burned off, but the leaves still held a faint dampness. The air smelled green — vegetal and mineral, the scent of soil that has not dried out.
Arimura-san's fields sit at roughly 270 meters above sea level. In midwinter, temperatures drop to minus four, sometimes minus ten. Not the tropical Kagoshima most people imagine.
The first flush arrives two to three weeks later than on the plains below. In a market that rewards early shipment with higher prices, three weeks is an eternity. The Arimura family could not compete on speed. So they chose a different path — if their tea would always reach the market late, they would make it worth the wait.
That decision, made decades ago, is the reason their tea has won Japan's highest award four times.
Four national championships. Arimura Tea Factory.
The National Tea Fair is the competition that matters. Producers from every corner of Japan send their finest — over a hundred entries in the 10-kilogram sencha category alone. Arimura Tea Factory has taken the Minister of Agriculture, Forestry and Fisheries Award — the top prize — four times: 1999, 2011, 2016, and 2019.
Competitions are not the whole story, of course. But winning the highest honor four times, against the best in the country, is not something that happens by luck.
They have also offered tea to the Emperor at the Daijosai — the sacred enthronement ceremony held once per imperial reign ceremony and won gold at a green tea competition in Paris. The accolades are real. But what I remember most is not the awards — it is the first sip.
Seventy years, three generations
Arimura Tea Factory is a family operation. Yukio-san, the second generation. Koji-san, the third. Yukiryo-san, the fourth — still in his early years as a tea maker when we visited.
"The factory started in 1953, so it has been about seventy years now. My father — the founder — he passed away the same year. I took over the business at sixteen."
Yukio-san was eighty-five when we met him, still out in the fields. Sixteen to eighty-five. That is nearly seventy harvests.
For decades he ran the operation alone. Then Koji-san joined after university. Three years before our visit, Yukiryo-san came aboard after graduating from agricultural college. The current team. Three people, three generations, the same fields.
The times have changed around them — market dynamics, processing technology, consumer tastes — but the founding principle has held for seventy years: make tea that is fragrant, make tea that is good.
Watching the three of them work side by side, there was an easy rhythm. Yukio-san would say something over his shoulder — half instruction, half memory — and Koji-san would nod without looking up. Yukiryo-san listened and moved quietly between them. No one raised their voice. No one needed to.
Fog, shade, and a concentration of umami
The first time I drank Arimura-san's tea, two things stopped me. The umami — dense, concentrated, spreading across the tongue the moment it entered my mouth. And the aroma, layered in a way I had not expected.
That umami comes from two forces working together. The fog itself acts as a natural curtain, softening sunlight and coaxing the leaves to develop more amino acids. On top of that, the Arimura family practices kabuse — covering the plants under shade cloth before harvest — amplifying what the fog has already begun.
And then, the fragrance. Each cultivar carries its own character: Saeakari with a sweet, chestnut-like warmth. Okumidori, cool and clean. Saemidori, a gentle sweetness like fresh green leaves. What ties them together is the hika — the roasted aroma coaxed out during the final firing stage. The balance between cultivar character and that finishing fire is precise, almost musical. It is an aroma that belongs to Arimura Tea Factory and no one else.
I poured a second cup and let it cool. As the temperature dropped, the aroma shifted — the roasted warmth receded and something sweeter, almost floral, came through underneath. The liquor was a pale gold, lighter than I expected from leaves this deeply shaded. It sat on the tongue with a viscous weight, then left a clean, lingering finish.
The secret, Koji-san told us, is in the processing — drawing out each cultivar's strengths without masking what the terroir has already given.
"How much of the leaf's flavor can you preserve."
"With tea, even if the leaf starts at a hundred, the factory is never going to make it a hundred and twenty. If you can keep it at a hundred, that is the best you can hope for — but it always drops. How much of the leaf's original flavor you can hold onto, how clean you can make the finished tea without losing what was there — that is the skill. That is the craft. And you spend your whole life experimenting, trying things, to get a little closer."
Koji-san said this matter-of-factly, the way someone talks about something they have thought about for a very long time.
Most of Arimura's tea is processed as chumushi — medium-steamed. Kirishima has traditionally been a region of lighter steaming, and the choice of medium is deliberate.
Steam longer and you get a tea with less astringency and brighter color — but the original aroma fades. Steam shorter and you preserve the fragrance, though the astringency sharpens and the raw leaf must be picked young and soft. Medium steaming is where the Arimura family found their balance: enough heat to round out the bitterness, not so much that it erases what the fog and altitude put there in the first place.
Kirishima's leaves grow slowly in the cool, damp air. They arrive at the factory already soft, already tender. Deep steaming would be redundant — stripping out flavor the mountain spent months building.
"Making tea is studying, every single year. Decades of it. You make plenty of mistakes. But once you make one, you never repeat it. You try to keep the failures small, and you try not to fail at all — but you keep learning. That is all there is to it, really."
You only get one first flush a year. In twenty years of tea-making, that is twenty chances. Twenty springs to refine your hands, your timing, your instinct for when the leaf is ready. The skills Yukio-san built over seventy of those springs are now passing to Koji-san, and from Koji-san to Yukiryo-san, who at the time of our visit had been making tea for just three years.
A young producer still finding his footing — and a future we hope to watch unfold.
Comfort, and a small measure of happiness
Before we left, I asked what kind of tea Arimura Tea Factory is ultimately trying to make.
"If I do not make a tea that I myself think is good, no one else will think so either. In this busy world, if someone can drink a cup and just — breathe, for a moment. Feel a little calmer. That is what I am aiming for."
There is a detail about the Arimura family that I did not notice until later. Yukio. Koji. Yukiryo. Every name in the family carries the character ko — 幸 — meaning happiness.
And true to the name, their tea does bring something close to that. A small comfort. A quiet moment in a day that moves too fast.
Perhaps that is what seventy years of care sounds like when it reaches the cup — not a declaration, but a breath. A pause that asks nothing of you except to sit, and drink, and let the warmth settle.
