The investment case
Why this farm makes money.
The value ladder
The same leaf can leave a farm as raw tea, or as finished Matcha at many times the price. Satoen grinds on site, so the crop climbs into its highest-value category before it is ever sold.
Five harvests a year
Japanese tea in Japan gives two or three crops. The Vân Hồ plateau supports five, thanks to its altitude, fog and cool air. The same asset simply works more of the calendar.
Field to factory, one site
Cultivation, steaming, Tencha, grinding and packaging under one roof. The margin that usually belongs to a chain of middlemen stays inside the operation.
A global sales network
Acquired into the Inabata group in 2025. The Japanese trading house has publicly committed to expanding this tea business across Asia, Europe and North America.
The offering
What you would be investing in.
Not the brand, and not a promise: a security issued by the dedicated vehicle that holds the interest in this farm, with the rights written down before anyone invests.
The operation
Japanese tea, grown in Vietnam.
Satoen's tea heritage begins in Japan in 1948. Its agricultural specialists spent more than twenty years studying Vietnam before choosing Vân Hồ: altitude above 1,000 meters, heavy fog, cool air and rich soil. These are Japanese growing conditions at a Vietnamese cost base. The Vietnam company was founded in 2014.
The product list runs from Sencha and Houjicha to finished Matcha, sold to food and beverage businesses, café chains and international partners, including private-label manufacturing. The operation cites GLOBALG.A.P., HACCP and HALAL certifications.
