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.
