Oishii, the vertical indoor strawberry farming company, raised $150 million in a Series C funding round.
Sparx Asset Management led the latest investment round with participation from Nomura Real Estate Development Co., Misumi Group, and Mizuho Bank.
Including the Series C round, Oishii has raised a total of $370 million in funding since its founding in 2016.
The Series C capital comes less than two years after the company secured a $150 million Series B round to expand into the Chicago and Mid-Atlantic retail markets.
With the first closing of Series C financing, Oishii plans to increase production capacity, advance robotics integration, expand farm infrastructure, and develop new product formats within its Smart Farm model, while continuing to invest in R&D and innovation capabilities across the United States and Japan.
“Since our Series A investment in 2019, we have continuously supported Oishii Farm’s growth. It is truly inspiring to see the vision we shared at that time steadily becoming a reality, as the company advances seamlessly from research and development to proof of concept and commercialization,” said Shuhei Abe, President & CEO of Sparx Asset Management.
Robotics and automation have become central to Oishii’s approach to scaling strawberry production with greater consistency, precision, and quality control. Following the acquisition of Tortuga AgTech in 2025, the company expanded those capabilities with additional harvesting robotics and engineering expertise. Earlier this year, Oishii also announced a strategic partnership with Misumi Group Inc., a global supplier of manufacturing and automation components, to support its growing automation and manufacturing needs across the U.S. and Japan.
“This funding marks a new phase for Oishii as we scale what we’ve built, with deeper confidence in the decisions we’ve made and the role we can play in bringing high-quality produce to more people, said Hiroki Koga, Co-Founder and CEO of Oishii.”
