Oishii, operator of what it claims is the world’s largest indoor vertical strawberry farm, has secured US$150 million in Series C funding to expand production capacity and advance its robotics-integrated growing model across the United States and Japan.

SPARX Asset Management led the financing round, with participation from Nomura Real Estate Development, MISUMI Group, Mizuho Bank, and other investors. The capital injection brings Oishii’s total funding to $370 million since the company was founded in 2016.

Central to Oishii’s strategy is the integration of robotics and automation throughout its growing operations. The company acquired Tortuga AgTech in 2025, adding harvesting robotics technology and engineering capabilities to its platform. It has also partnered with MISUMI Group, a global manufacturing and automation supplier, to support its equipment and component needs as it expands facilities.

Oishii is developing an Open Innovation Center in Tokyo to strengthen its research and development capabilities and advance its growing technology.

When Oishii entered the market in 2018, it positioned its flagship Omakase Berry as an ultra-premium product priced at nearly $50 per tray. The company has since broadened its product lineup and pricing structure to reach a wider consumer base.

Oishii currently distributes across 18 U.S. states and recently expanded into Toronto, Canada, marking its first international retail market.

“When we chose strawberries, we knew we were selecting one of the hardest paths in indoor farming,” said Hiroki Koga, co-founder and CEO of Oishii. “They require precision at every stage, from pollination and harvesting to freshness and shelf life, and there were moments along the way where solving one challenge revealed the next one underneath it. 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.”

The company plans to use the new funding to increase production capacity, expand farm infrastructure, deepen robotics integration, and develop additional product formats while continuing to invest in research and development across both countries.
