Ultimate Guide to Kamairi-Cha (2026)

Japan's oldest green tea method, and the one that smells nothing like it.

There is a moment I remember clearly the first time I smelled kamairi-cha dry in the bag. I was expecting something grassy, something Japanese. What came out instead was warm and nutty, a little roasty, with that unmistakable fragrance of leaves meeting a hot pan. It did not smell Japanese at all. It smelled like something between a Longjing and a tamaryokucha, and I had to remind myself that this was a Japanese green tea I was holding.

That is not an accident. Kamairi-cha is made by a Chinese method that the rest of Japan eventually abandoned, kept alive by a handful of mountain communities in Kyushu who simply never stopped doing what they had always done. We occasionally feature kamairi-cha through the Japanese Tea Travelers program, and if you are reading this because you have one in hand, this is the full story behind what you are drinking.

Kamairi-cha (釜炒り茶) is a Japanese green tea made by pan-firing rather than steaming. Instead of the blast of steam that halts oxidation in sencha or gyokuro, freshly picked leaves go straight into a hot iron pan at around 300 to 400 degrees Celsius, where they are moved continuously until the oxidation stops and the leaves take on their distinctive curled, comma-like shape. The result is a clear golden infusion with very low astringency, a natural sweetness, and a warm roasted fragrance called kama-ka (釜香) that you will not find in any other Japanese tea.

It is made almost exclusively in Kyushu, concentrated in Miyazaki, Kumamoto, and Saga prefectures. It accounts for less than one percent of Japanese tea production.¹ It goes by a few names: kamairisei tamaryokucha (釜炒り製玉緑茶) is the formal one, kamaguri-cha (釜ぐり茶) the casual regional one. And historically, before Japan's tea world was turned upside down in the eighteenth century, this was simply how everyone drank green tea.

If you want to know why this tea smells the way it does, why "sencha" once meant something completely different, and why the last artisan making kamairi-cha by hand in Ureshino recently said that when he stops, it is over, read on.

The name is exactly what it says. Kama (釜) is the iron pan. Iru (炒る) means to roast or stir-fry in a dry pan, the same motion you'd use to toast sesame seeds or dry-roast nuts. Put them together with cha (茶), and you get "tea roasted in the pan." There is no gap between the name and the method.

The kanji 炒 is worth a closer look. It implies heat with continuous movement, the exact same character used in Chinese cooking for stir-frying. This is not a coincidence. The technique is Chinese, and the language shows it.

The alternate name kamaguri-cha (釜ぐり茶) tells a different part of the story. Guri is an onomatopoeia for the curling motion of the leaves as they tumble around the hot pan. The name describes what you are watching happen. In Miyazaki, kamaguri is the more common term; in Ureshino and Saga, you are more likely to hear kamairi or the full formal name.¹⁰

The easiest way to understand kamairi-cha is to start with what it does not taste like. There is no grassy bite here, no marine or seaweed note, none of that sharp chlorophyll intensity that makes a good sencha so unmistakably Japanese. All of that comes from steaming, and kamairi-cha never goes near a steamer.

What you get instead is the kama-ka (釜香), the signature roasted fragrance that comes from firing fresh leaves in a hot iron pan. Think toasted chestnut, warm sesame, a little something that rhymes with popcorn without quite being popcorn. It is a fragrance that has no equivalent in any steamed Japanese tea, but will feel immediately familiar if you drink Chinese green teas. That is because the same heat-on-fresh-leaf process that creates kama-ka also creates the fragrance in Longjing.³

The cup itself is a clear, clean gold. Soft on the palate. Low astringency. There is a natural sweetness that comes forward once the bite of catechins is out of the way. Producers often describe it as 飲み飽きない (nomi-akinai), literally "a tea you never tire of drinking," and that tracks with the experience.⁴ It does not demand anything from you. It just keeps being pleasant, cup after cup.

The whole story of kamairi-cha comes down to one decision made at the very start of processing: use a hot pan instead of steam.

When tea leaves are picked, they start oxidizing immediately, the same way a sliced apple turns brown. Every Japanese green tea has to stop that process fast to lock in the green character. The standard Japanese approach, used for sencha, gyokuro, and almost everything else, is to rush the leaves into a steamer. The steam stops oxidation within seconds and locks in that vivid green, grassy profile.

Kamairi-cha does the same job with a hot iron pan instead. Freshly picked leaves go into a machine called an iriha-ki (入り葉機), the mechanized version of the original hand-held kama, heated to around 300 to 350 degrees Celsius.¹⁰ The leaves are kept moving continuously, a bit like tossing something in a wok, to prevent scorching. This firing phase lasts around ten minutes, and this is the moment where the kama-ka is born.

After firing, the leaves go through a rolling and drying process at lower temperatures. Because there is no final shaping step, the leaves are not forced into needle shapes the way sencha leaves are. They curl and tumble naturally, producing the irregular comma shape that kamairi-cha is known for. That shape, incidentally, is called magatama (勾玉) after the prehistoric curved jewels found in ancient Japanese burial sites.¹

A less common variant called kamanobi-cha (釜伸び茶) does go through a needle-shaping step at the end, producing a pan-fired tea that looks more like sencha. It is sometimes sold as an easier entry point for people more used to the sencha form.¹

Before mechanization, there were two distinct hand-firing schools, and they are still how the different regional styles are identified today.

The Ureshino style (嬉野製法) from Saga uses a kama tilted at 45 degrees toward the tea maker. That angle creates a natural rolling motion as the maker sweeps leaves upward with both hands, producing a rounder, more uniform leaf.¹² Interestingly, this tilted-pan approach has some kinship with how Longjing is made in China, where the hand presses and drags along the curved surface of the pan at an angle.

The Aoyanagi style (青柳製法) from Kumamoto, now also associated with Miyazaki, uses a flat-bottomed pan set parallel to the ground, more like a general cooking wok. The motion is different, the resulting leaf shape a little less uniform. This was historically the more widespread of the two styles, the one used in home firing across western Japan.¹²

Today, both have been largely replaced by rotating drum machines. Traditional hand-firing survives at a very small number of farms, mostly in Miyazaki and Kumamoto.⁹

Here is something worth sitting with: before the mid-1700s, kamairi-cha was not a specialty. It was not a regional curiosity. It was just tea. It was what people across Japan drank when they wanted a cup of loose-leaf green tea.

The story of how that changed is one of the more fascinating reversals in food history.

It Came From China, Through Kyushu

Several accounts exist for how pan-firing arrived in Japan. The one most consistently cited in Japanese historical sources, and the one that Ureshino claims as its founding moment, places the origin in 1504. A Chinese potter named Ko Reimin (紅令民) arrived in Ureshino, Saga Prefecture, carrying a nankingama (南京釜), a large iron pan of the Nanjing style, and introduced the pan-firing method that was current in China at the time.²'⁵

The potter connection is not incidental. The same wave of Ming-dynasty craftsmen who brought the pan and the tea method also brought ceramic techniques that would eventually give rise to the Karatsu and Arita ceramic traditions. Tea knowledge and kiln knowledge traveled together through the same migration routes.

The Kumamoto tradition, the Aoyanagi style, has its own origin story: Korean craftsmen who settled in the Yamato district after helping build Kumamoto Castle under the daimyo Kato Kiyomasa (加藤清正) in the early Edo period.⁶

The Long Years of Dominance

For nearly two centuries after Ko Reimin, kamairi-cha spread through Kyushu and beyond. By the mid-Edo period, a German physician named Engelbert Kaempfer was living in Japan and wrote that the Japanese made their green tea by the Chinese method of dry cooking in a wok.⁹ He was describing kamairi-cha as an everyday national practice. At that point, alongside the matcha culture of the temples and the warrior elite, pan-fired loose-leaf tea was simply how ordinary people drank tea.

The Zen monk Ingen Ryuki (隠元隆琦), who arrived from China in 1654, helped solidify the practice further by spreading the Ming-dynasty habit of simply pouring hot water over loose dried leaves. This gave pan-fired tea a cultural framework among the educated class.⁷

Then a Farmer Changed Everything

In 1738, a tea farmer named Nagatani Soen (永谷宗円) from Ujitawara in Kyoto Prefecture finished fifteen years of experimentation and brought a completely new kind of tea to market. He steamed the leaves to stop oxidation, then rolled and dried them into vivid green needles. The result was a tea that looked and tasted unlike anything before it: brilliant green, grassy, fresh.⁷

The color alone was revolutionary. Where kamairi-cha brews a warm golden cup, Nagatani Soen's tea brewed something startlingly green, at a time when the only other green tea was matcha. It spread rapidly through the country.

Here is the part most people do not know: for a long time after Nagatani Soen's invention, the word sencha (煎茶) still referred to what we now call kamairi tamaryokucha. The vocabulary gradually shifted as the new tea took over, until the steamed needle tea had claimed the name entirely, and the original pan-fired tradition became, at best, a regional specialty in Kyushu.⁷

The Slow Disappearance

The modern era was not kind to kamairi-cha. As Japan industrialized its tea production from the 1950s onward, the economics became brutal. A modern sencha processing line can handle around 180 kilograms of tea per hour. A traditional kamairi-cha machine processes ten to forty kilograms in the same time. The finished product sells at similar prices. One Kumamoto producer summarized it plainly: "Kamairicha just doesn't pay off."⁹

At their peak in the 1960s, Kyushu had more than 900 kamairi-cha factories.⁶ Today, the method accounts for less than one percent of Japanese tea production. In Ureshino itself, where it all began, the vast majority of production has shifted to steamed tamaryokucha, with traditional hand-fired kamairi-cha now made by only a handful of producers.⁶

Despite Ureshino's place in the history books, the real center of kamairi-cha production today is Miyazaki Prefecture, specifically the mountain towns of Gokase (五ヶ瀬町) and Takachiho (高千穂町) in the northern highlands. According to MAFF production data, Miyazaki accounts for 72 percent of national kamairi-cha output.⁸ This surprises people, but it is consistent across sources.¹⁰'¹¹

Gokase and Takachiho

Gokase and Takachiho sit above 600 meters in elevation. The dramatic temperature swings between day and night at altitude push the tea plant to develop more aromatic compounds in the leaf, which is one reason the kama-ka in Miyazaki kamairi-cha tends to be particularly vivid.¹³

The region has been recognized by the United Nations Food and Agriculture Organization as a Globally Important Agricultural Heritage System (GIAHS) since 2015, the Takachihogo-Shiibayama designation, which covers the traditional mountain agroforestry system that includes shiitake, small-scale wagyu, terraced rice, and kamairi-cha.¹³ It is not a quality mark, but it does mean that the international community has formally recognized this farming system as worth preserving.

Gokase and Takachiho are also consistent performers at the national tea competition in Japan. The sanchi-sho (産地賞), the regional excellence award at the 全国茶品評会 (Zenkoku Cha Hinpyokai), has regularly gone to producers from these two towns in the kamairi-cha category, which speaks to the depth of skill concentrated in this region.⁸

Ureshino

Ureshino is where the story starts, and it still produces kamairi-cha, but only just. The shift to steamed tamaryokucha (explained next) has been almost total.⁶

One Ureshino tea artisan, when asked about the state of traditional hand-fired kamairi-cha in the town, described how only he and one producer in his eighties were still doing it the old way. When his senior colleague passed away, the message was clear: "If I stop, that's the end of it."⁴ His annual output by the traditional hand-firing method is around 20 kilograms. That is the scale of what survives.

Kumamoto

Kumamoto's Aoyagi tradition is equally fragile. Field research conducted around 2009 found only two producers in the Izumimachi area still making kamairi-cha in the traditional style, one of them having resumed after a serious illness and working only as much as his health allowed.⁸

This is worth taking a moment to untangle, because even in Japan the terms trip people up.

Tamaryokucha (玉緑茶) simply means "round green tea," describing the leaf shape. The name was officially settled in 1932 in a competition organized by the Tea Industry Association (茶業組合中央会議所), the predecessor body to today's Japan Tea Industry Central Association.⁶ It won out over alternatives including Magatama-cha and Marucha.

The problem is that tamaryokucha now covers two entirely different teas made by two entirely different methods. Kamairisei tamaryokucha (釜炒り製玉緑茶) is pan-fired. Mushisei tamaryokucha (蒸し製玉緑茶), also called guricha (ぐり茶), is steamed. Both produce the comma-shaped leaf, but they taste completely different. The steamed version is closer to a light sencha, still grassy and green. The pan-fired version is kamairi-cha, with the kama-ka fragrance and the golden cup.¹

When a shop says "tamaryokucha" without a prefix, they almost certainly mean the steamed version, which accounts for over 90 percent of tamaryokucha available today.⁶ If you want kamairi-cha specifically, ask for kamairisei, or just say kamairi-cha.

The steamed version only exists because of kamairi-cha, by the way. It was created in the 1930s when Japanese producers wanted to sell into Soviet markets where Chinese pan-fired teas were popular. They produced a tea with the same visual form but using the steaming equipment they already had. It turned out to be a commercially successful product, eventually more dominant than the original.⁶

The kama-ka is the heart of kamairi-cha, and it is worth understanding where it comes from, even without going into the chemistry.

When fresh tea leaves hit a very hot pan, the heat triggers a set of reactions between the natural sugars and amino acids already present in the leaf. It is the same thing that happens when bread bakes and goes golden on the crust, or when coffee roasts, or when you toast sesame seeds. The heat builds complex aromatic compounds that simply do not exist in raw leaf or in steamed tea. You cannot recreate this with a steamer, no matter how hot you run it.³

Researchers who have compared the aroma profiles of kamairi-cha, Longjing, and sencha found that sencha had around 32 distinct aromatic compounds. Both kamairi-cha and Longjing had more than 50. The extra compounds are the ones born in the pan. This is why kamairi-cha and Longjing smell more alike than kamairi-cha and sencha do, even though kamairi-cha is grown in Japan by Japanese farmers.³

It also explains why kamairi-cha does not taste like hojicha, even though both involve roasting. Hojicha starts with tea that has already been fully processed, then roasts it a second time. Kamairi-cha fires fresh, raw leaf. The starting material is completely different, and so is the result.

This part of the story deserves to be told plainly.

The economics do not work. A modern sencha line processes roughly 180 kilograms per hour. Traditional kamairi-cha machines do ten to forty kilograms in the same time. The finished product sells at similar prices.⁸ There is no scenario where the math favors kamairi-cha for a producer trying to run a viable business.

What keeps it alive is stubbornness, skill, and the belief that something irreplaceable would be lost. Farmers in Gokase have committed to the method knowing full well what it costs them.¹⁰ The national tea competition (全国茶品評会) has seen multiple top awards go to Gokase and Takachiho producers in the kamairi-cha category, which demonstrates that the quality ceiling of this tea is genuinely competitive despite the method's diminished status.

The GIAHS designation for the Gokase-Takachiho region gives some institutional weight to preservation, but it does not change the economics.¹³ What changes the economics is people specifically choosing to buy kamairi-cha, which is why we feel it is worth carrying through the Japanese Tea Travelers program and worth explaining this thoroughly.

Kamairi-cha is one of the more forgiving Japanese teas to brew, and one of the few that genuinely benefits from higher water temperatures. The reason is structural: because kamairi-cha skips the rolling steps that break down leaf cells in sencha, the leaf tissue stays largely intact and compounds extract more slowly. This means you need slightly more heat to draw out the flavour, and you have a wider margin for error than with sencha or gyokuro.⁸ The kama-ka aromatics also express better with heat than without.

Use around 5 to 6 grams (1–1.25 tsp) to 200ml (6.8 fl oz) of water at 85 to 90°C (185–194°F) and steep for 60 to 90 seconds.¹² Because the cell structure is intact, the tea holds up well across multiple infusions: for the second cup, use hotter water and a shorter steep, and the flavour will still be there.⁸

Cold brew works well for kamairi-cha. The roasted notes mellow in cold water and the result is clean and naturally sweet. Steep using cold water and leave in the refrigerator for several hours. Parameters will vary by leaf quantity and preference, so experiment to find your balance.

Most kamairi-cha uses Yabukita (やぶきた), simply because it is the cultivar on most Japanese farms. Good Yabukita kamairi-cha, especially from Gokase, can be excellent.¹⁰

A few cultivars have been developed specifically for pan-firing, almost all of them in Miyazaki. Mine Kaori (みねかおり) is one, registered as a kamairi-cha cultivar and known for its expressive kama-ka.¹⁰ Minami Sayaka (みなみさやか) is another that, despite being a sencha cultivar on paper, produces outstanding kamairi-cha in the hands of Gokase producers.¹⁰ Producers who grow many different cultivars are effectively using kamairi-cha as a canvas for cultivar expression, which produces some of the most interesting cups in the category.

No, and it is an easy mistake to make because both involve heat. The critical difference is timing. Kamairi-cha applies heat to fresh, just-picked leaves as the very first step of processing. Hojicha takes tea that has already been fully processed, usually sencha or bancha, and roasts it a second time. Different starting material, different reactions, completely different result. Kamairi-cha is a green tea. Hojicha is a roasted tea made from an already-finished green tea.

Because the method is Chinese. The same heat-on-fresh-leaf process that creates kama-ka in kamairi-cha also creates the signature fragrance in Longjing and other Chinese pan-fired teas.³ The cultivars are different, the terroir is different, the rolling technique is different, but the heat chemistry is the same. Kamairi-cha is a genuine bridge between Chinese and Japanese tea traditions, which is exactly what you would expect from a method that arrived in Japan via Chinese potters in the sixteenth century.

Historically yes, but practically not really anymore. Ureshino is where kamairi-cha entered Japan's documented history, but today the vast majority of Ureshino's production is steamed tamaryokucha.⁶ The majority of kamairi-cha by volume comes from Miyazaki, especially Gokase and Takachiho.⁸'¹¹

Yes, genuinely. The pan-firing reduces the compounds responsible for bitterness and astringency compared to steamed green tea. The result is soft, sweet, and easy to drink. It is one of the better entry points into Japanese green tea for anyone who has bounced off sencha.
