'SAICHA' Beauty Oil Using 'Tea Seeds' from Abandoned Farmland 'SAICHA' is a skincare brand that designs its value based on the premise of limitation, using the rare resource of 'tea seeds' grown on abandoned farmland in Shizuoka Prefecture, Japan's largest tea-producing region.

The main raw material, tea seeds, is a rare natural resource affected by climate and the natural environment. At 'SAICHA', we cherish this limited blessing and create our products based on the philosophy of 'protecting quality' rather than 'increasing quantity'.

We also pay attention to formulation design that is easy to continue using daily while utilizing naturally derived ingredients. As an entity that connects nature, people, and society, we aim to be a brand that nurtures sustainable value.
