Chikusendō is a historic tea whisk (chasen) workshop in Takayama, Ikoma, Nara Prefecture, Japan — the birthplace of traditional chasen making for over 500 years. The craftspeople of Chikusendō hand-carve whisks from locally grown bamboo, splitting and shaving each piece into dozens of fine tines (typically 36–120). The process demands years of apprenticeship and precise manual skill. Their work preserves the Takayama chasen tradition, known for flexibility, even frothing, and longevity. Today, Chikusendō is recognized as one of the few remaining makers producing authentic, handmade whisks used in both traditional tea ceremony and modern matcha preparation — a benchmark of quality and craftsmanship.

Now led by the seventh generation, DENSHIRO combines traditional kabazaiku techniques with modern design, producing pieces prized for their natural beauty, airtight qualities, and warm, tactile feel. Their work represents the highest level of craftsmanship in Akita and remains one of Japan’s best-known makers of cherry-bark tea ware.

We are honored to be able to share the products crafted by the Furukawa family, a husband and wife operation, based in Uji City, just south of Kyoto. Both humble and charming, they'd never let on that they have been awarded Japan's top prize for matcha. But everyone who knows them says the same thing: They never cut corners, and you can taste their passion in the tea they make. In addition to producing peerless matcha, they have a deep respect for their land and act as its stewards, practicing an all-natural approach to garden management. Year after year, they quietly craft teas of the highest order, helping all discover the magic of nature.

While the exact lineage of their family remains a mystery since the family records were lost in a flood a century ago, Furukawa san finds it safe to say he is roughly the sixth generation to produce high quality Uji tencha under the family name.

Kanji Nakata is a Japanese tea producer known for making traditional Awa Bancha in the mountain town of Kamikatsu on Shikoku Island. Unlike many Awa Bancha makers who inherited tea production through generations of family farming, Nakata is a first-generation tea grower who came to tea after working previously as a schoolteacher.

Nakata specializes in Awa Bancha (阿波晩茶), one of Japan’s rare post-fermented teas. The tea is produced through a labor-intensive process in which summer-harvested tea leaves are boiled, kneaded, packed tightly into wooden barrels, and fermented anaerobically with naturally occurring lactic acid bacteria before being sun dried. This method has been practiced in Tokushima for centuries and produces a tea known for its gentle acidity, low bitterness, and low caffeine content.

Maruhachi Seichajo is one of Japan’s most respected hōjicha and bōcha tea producers, best known for its signature “Kenjo Kaga Boucha,” a roasted stem tea closely associated with the tea culture of Kanazawa and the wider Kaga region of Ishikawa Prefecture.

Founded in 1863 during the late Edo period, the company has remained family operated for six generations. Based in Kaga City, Maruhachi Seichajo developed its reputation through a highly refined approach to roasting tea stems (茎茶 / kukicha), particularly stems from the first spring harvest.

Based in Yakushima since 1982, ceramic artist Masayuki Yamashita creates pottery deeply rooted in the island’s rich natural environment. Working primarily with wood-fired kilns, he uses local clay, ash, and the unpredictable effects of flame to produce vessels that embody both quiet simplicity and raw natural energy.

His works are often unglazed, allowing the interaction of fire, ash, and earth to create unique surfaces and textures impossible to replicate. Each piece carries subtle variations shaped by the kiln atmosphere, making every work one of a kind.

In addition to functional tableware, Yamashita also creates sculptural forms inspired by the forests, animals, and spirit of Yakushima. His pottery reflects a deep dialogue with nature — timeless objects that bring warmth, texture, and a sense of place into everyday life.

Studio ceramics are created by groups of artisans, often working collectively within shared workshop spaces. These studios tend to represent a region rather than a single maker, reflecting a philosophy that values the work itself above the individual who created it. This ethos—rooted in the Mingei movement—celebrates the beauty of useful, everyday objects rather than elevating craft solely as fine art. We are proud to collaborate with several such studios and deeply respect their approach.

The Sakamoto family produces traditional Kamairicha (pan-fired green tea) in Gokase, a mountainous area in northern Miyazaki known for its cool climate and misty highlands. Their teas are grown at high elevation, where slower leaf growth enhances aroma and clarity. Using the region’s historic pan-firing method instead of steaming, the Sakamotos create teas with a lightly toasty fragrance, clean flavor, and gentle sweetness—a classic expression of Gokase’s fragrance-first style.

We are honored to work with Tamaya, a Kyoto-based operation founded in 1949, to source our legendary Nagano Soba Cha. Soba Cha grown by collective farmers in Nagano is rarely available in the retail marketplace, as much of it is reserved for Japan’s finest restaurants. Tamaya works on our behalf to locate and secure pinnacle-grade domestic buckwheat directly from producers. Manufactured in a state-of-the-art facility in Nagano, the consistency and quality of the Soba Cha we receive are truly unparalleled.

Taro Tabuchi is a ceramic artist born in 1977. After graduating from the Crafts Department of Osaka University of Arts, he received the Grand Prize at the 21st Asahi Modern Craft Exhibition in 2003, and he was selected as one of the artists at the 7th International Ceramics Competition Mino in 2005.

In 2007, he returned to his birthplace, Kagawa, and constructed "Ana-gama (hole kiln)". While many artists choose to use gas and electric kiln as they are easier to control, he gathers firewood himself in the mountains and continues to create white porcelain by firing in a wood-fired kiln. The variation of fire and ashes that come out of wood-fired kiln produces unique color and pattern variations. In some cases, up to 50% of the work that is fired will be ruined in the kiln, unable to be salvaged or sold. But what comes out alive is cloaked in a mystery and beauty that must be seen in person to fully.

Tatsuji Takahashi is a tea farmer from Honyama, Shizuoka Prefecture, known for producing small-batch Japanese oolong tea, a rare style in Japan. Working in the cool, misty mountains of Honyama, he uses the region’s slow-growing conditions to preserve amino acids and deepen flavor.

His work represents a blend of Japanese terroir and modern craftsmanship, making him a leading figure in Japan’s emerging oolong category.

Tetsuya Otani’s philosophy integrates daily life and craft, seeing pottery as a way to shape how people live and interact with objects.

Our relationship with Tsuji-San is a storied one, as he was the first producer to represent Uji in our catalog, and Kettl was the first partner to bring his teas to the international stage.

In the intervening years, Kiyoharu Tsuji's production has expanded beyond just pinnacle grade, single cultivar matcha offerings to include blended matcha and houjicha. Koki Tsuji, Kiyoharu's son, has joined his practice and taken the lead on one of Kettl's core offerings—Shirakawa Legacy. We are honored to work with one of the pioneers of modern matcha and the next generation of emerging voices.

Tsunagu Sonogi Tea Farmers is a collective of young tea producers based in Higashisonogi, Nagasaki Prefecture, a historic tea-growing region overlooking Ōmura Bay on Kyushu. The group was founded by a new generation of farmers from long-established tea families who wanted to preserve Sonogi tea culture while creating a more sustainable future for regional tea production.  

The collective originally began with six producers under the name “Tsunagu Sonogi Tea Farmers” — the word tsunagu meaning “to connect.” Their goal was to connect farmers directly with international consumers, revitalize Nagasaki tea, and create a collaborative model rather than competing individually. Over time, the group evolved into a smaller core collective of four farmers, later also operating internationally under the name “Forthees.”

We work closely with a network of small farms through our connections to Japan’s regional tea markets. Each prefecture maintains its own auction system, where teas from local producers are bid on. Our trusted partners participate in these markets on our behalf, giving us access to teas from multiple farmers—often thoughtfully blended—to achieve a balance of exceptional quality and consistent volume. Since a single tea can often draw from the harvests of a dozen or more producers, we consider it best described as the work of multiple small growers—comparable to a field blend in the world of wine, where balance and character emerge from the harmony of many sources.

The Waki family are tea producers who work their own fields in the village of Shingu, located in Ehime prefecture, in addition to processing tea for local farmers.
