Oishii, the premium indoor-farming startup known for its AI-pollinated strawberries, announced on May 13, 2026, the first closing of a $150 million Series C financing round, according to a company statement distributed via PR Newswire. The round was led by SPARX Asset Management, with participation from Nomura Real Estate Development, MISUMI Group, and Mizuho Bank.
The company said the capital will go toward increasing production capacity, deepening robotics integration into its “Smart Farm” model, expanding farm infrastructure, and developing new product formats across the United States and Japan.
Oishii has now raised roughly $370 million since its 2016 founding. Industry coverage framed the round as a notable counterpoint to a wave of vertical-farming failures, attributing the company’s resilience to a premium-product strategy and improving unit economics.
Because this is described as a “first close,” additional commitments to the Series C may follow. Japanese reporting valued the disclosed tranche at approximately ¥24 billion, ranking it the largest Japan-linked startup raise of May 2026.
