Tosa Tea：Discover Japan’s “best-kept secret,” one cup at a time
High in the misty mountains of Kochi Prefecture, far from the neon glow of Japan’s big cities, a quiet tradition continues. Here, where the mornings begin in drifting fog and the rivers run glass clear, tea farmers tend their fields with the same patience and precision their families have practiced for generations.
This is Tosa tea.
Tosa Tea refers to tea made from leaves grown in Kochi Prefecture and includes both green tea and black tea. “Sencha” (green tea, made by steaming and drying the leaves) and “hojicha” (green tea steamed, dried, and roasted at a high temperature), have gained popularity in recent years both as everyday drinks and as ingredients in sweets.
Unlike the bold intensity of matcha, Tosa tea offers something gentler: a clean, soft flavor shaped by mountain air, mineral rich soil, and slow, careful craftsmanship. Not mass-produced, nor rushed; every leaf is grown on steep mountain slopes, harvested and crafted with intention.
Every cup tells a story — of fog draped mornings, of hands stained green from fresh leaves, of a region that whispers rather than shouts.
For those seeking something rare, something real, Tosa tea is more than a drink. It’s a journey into Japan’s hidden heart.

Meet the Farmers Behind the Leaves
Nestled along the crystal-clear Niyodo River —famous for its “Niyodo Blue”—the areas of Hidaka Village and Niyodogawa Town have long been tied to tea cultivation. It’s common to see tea trees growing right in people’s gardens, thanks to the region’s ideal conditions: well-drained soil, adequate sunlight, and morning mist—perfect for producing Tosa tea.
Kiriyama Tea Farm in Hidaka Village began in the 1970s when local farmers came together with a dream to create something special. They cleared the land themselves and planted about 20 hectares of tea fields. By the mid-1990s, they shifted from just growing tea to crafting and selling their own products, helping to establish the Tosa tea brand in Kochi. Today, they offer hands-on experiences like roasting your own hojicha in a traditional hōroku pan and making custom tea canisters—an engaging way to connect with tea culture and the land it comes from.
Further upstream in Niyodogawa Town, tea farmers have opened cozy cafés and restaurants where visitors can enjoy Tosa tea through delicious food and drink, right in the heart of this tea-growing region.
As Kochi Prefecture is rich in mountains and rivers, Tsuno Town, home to the headwaters of the Shimanto River , stands out as a unique Tosa tea region. Around 17 tea farmers continue to grow and process tea here, cultivating steep mountain slopes and high plateaus.
Some tea fields reach elevations of around 600 meters above sea level. The large temperature differences between day and night, together with the mist that frequently forms in the mountains, give the tea from this region its uniquely rich and complex flavor. Taking advantage of these natural conditions, tea farmers in Tsuno Town carefully cultivate their tea using methods that respect the surrounding environment. Some farmers also produce Japanese black tea using the sencha cultivar “Yabukita”, while others practice environmentally conscious organic farming without the use of pesticides since the land was first cultivated.
Tea leaves vary in character depending on when they are harvested.
First harvest leaves, the earliest of the year, are picked from late April to mid-May and are of the highest quality, known for their rich flavor and natural sweetness.
Second harvest leaves, picked from mid-June to July, have a lighter, more refreshing taste with a slightly astringent note.

Tsuno Town is known for its creative use of tea leaves across all harvests—not just the prized first harvest, but also the mid and second harvest leaves. The mid harvest leaves (between the first and second harvest), known for their mild bitterness and astringency, are commonly enjoyed as an everyday tea. The second harvest tea, when roasted, transforms its bitterness into a deeper, richer flavor, producing “hojicha” characterized by a toasty aroma and naturally low caffeine. It’s tea that goes well with meals or sweets. This approach not only broadens the appeal of Tosa tea beyond “sencha” but also supports tea farmers and helps preserve the region’s tea culture for future generations.
Bring the Mountains to Your Cup
Kochi Prefecture offers plenty of cozy spots to enjoy Tosa tea with a meal or sweet treat. In the Niyodo River area, Tea Cafe Asunaro, a tea farmer–run restaurant, serves a set lunch featuring local specialties, and tea-infused udon noodles. They also use their tea in waffles, soft ice-cream, and smoothies—favorites among international visitors and Japanese alike. Sipping tea by the river, with the sound of flowing water, is a peaceful and memorable experience.
Nearby, along the Doi River(a tributary of the Niyodo River), the Ikegawa Cha-en Café , started by a group of tea farmers’ wives—offers delightful sweets like tea pudding and tea tiramisu, made with local leaves known for their balanced savory flavor and refreshing taste. Pairing these treats with outdoor adventures in Niyodogawa Town makes for a perfect day.
Even in Kochi City, the prefecture’s travel hub, you’ll find plenty of Tosa tea delights. Manten no Hoshi has locations in the city center and near the Kochi Interchange, offering hojicha daifuku, roll cakes, and roasted tea soft ice-cream. At the Tosa-cha Café in the arcade shopping street, you can sample teas from across Kochi with a seasonal dessert or lunch set—an ideal break during your travels.
