Fukushima Farmer Implements Groundwater Thermal Energy for Strawberry Cultivation
Sayuri Yasuda has adopted a groundwater thermal energy system for strawberry farming in Fukushima, reducing operational costs by 60%. This innovative method may enhance sweetness in strawberries while contributing to decarbonization efforts in agriculture.

Sayuri Yasuda has initiated strawberry cultivation using a groundwater thermal energy system, reducing maintenance costs by approximately 60% compared to conventional methods. The system, developed by Link-F Co., utilizes heat pumps to enhance soil temperature, supporting strawberry growth in a controlled environment.
Yasuda expanded her farm area to 950 square meters with the addition of a fourth greenhouse in autumn 2025. The thermal energy system enables efficient heating and cooling by leveraging the stable temperatures of groundwater.
Initial results indicate that strawberries produced under this system exhibit increased sweetness due to extended maturation periods. Despite current limited production, Yasuda is exploring branding opportunities for her strawberries, potentially marketing them as
