Called the "Land of the Gods" due to its central role in Japanese mythology, Takachiho is known mostly for its spiritual significance and dramatic waterfalls and gorges. In the tea world, Takachiho and its neighbouring villages of Gokase and Hinokage are known as the top producers of kamairicha. Introduced to this region from China in the 1300s, the once-common pan-firing technique of producing green tea has been perfected and preserved in this region. Today, kamairicha makes up less that 0.5% of Japanese tea. The mountainous terrain, wide temperature fluctuations between day and night, and abundant fog make the region ideal for growing high-quality tea.
Named after the famed kamairicha-producing town, this cultivar was selected from local zairai seedlings in 1953 at the Miyazaki Agricultural Research Institute. Coincidentally, that was the same year that the Yabukita cultivar was first registered. As its namesake suggests, this cultivar was developed specifically for kamairicha production, and as such develops a good flavour and aroma when pan-fired. Additionally, it has a slightly thicker leaf than most other cultivars, meaning it forms visually appealing curls as it is fired and dries.

Kai Seichaen (甲斐製茶園)
Nestled in the mountains of the "Land of the Gods" Takachiho, Kai Seichaen has been producing kamairicha for over 70 years and are dedicated to perfecting and preserving this centuries-old style of tea. Bolstered by their numerous awards (including the National MAFF Award, multiple Nihoncha Awards, and a Leafies), they strive to further improve their craft and grow tea in a way that suits the local environment, opting for organic cultivation. The mountainous terrain means their fields are small and terraced, requiring more individualised attention. Across their 520 acres, they grow eight cultivars.
Kai Seichaen is currently headed by fourth-generation tea farmer Kai Masaya (甲斐雅也) who works alongside his parents to continue their family farm. After taking over from them in 2010, he has expanded the farm, both in terms of cultivated area, but also in styles of tea. While he has been experimenting with producing oxidised teas such as black and oolong since 2005, a trip to Taiwan in 2012 and the purchase of a Taiwanese wilting machine, led to Kai-san's development of the award-winning wakoucha and oolong his grows today. In 2023, he obtained organic certification for his tea farm, and has changed their harvesting and cultivation practices to best suit their environment.
