Oishii Announces First Closing of $150M in Series C Financing as It Scales Its Indoor Smart Farm™ Model

Oishii, a leader in the indoor vertical farming sector, has successfully closed the first tranche of a $150 million Series C financing round, with the announcement made on May 13, 2026. The funding round was led by SPARX Asset Management Co., Ltd., with significant participation from Nomura Real Estate Development Co., Ltd., MISUMI Group Inc., and Mizuho Bank Ltd., among others. This capital injection is set to enhance Oishii's production capacity, advance its robotics integration, and expand its operational footprint across the United States and Japan.

Founded in 2016, Oishii has pioneered the development of the world's largest indoor vertical strawberry farm, utilizing its proprietary Smart Farm™ model. This innovative approach combines advanced technology, including robotics and automation, with traditional Japanese farming techniques to produce pesticide-free, Non-GMO strawberries year-round. The company has made significant strides in expanding its distribution network, currently reaching 18 states and recently entering the Toronto market as its first international retail location. Oishii's product offerings have also diversified, moving beyond its initial ultra-premium positioning to include more accessible price points and new product lines.

The strategic rationale behind this funding round is rooted in Oishii's commitment to scaling its operations while maintaining quality and consistency in its agricultural output. Robotics and automation play a crucial role in this strategy, enabling the company to enhance production efficiency and quality control. Following its acquisition of Tortuga AgTech in 2025, Oishii has further strengthened its capabilities in harvesting robotics and engineering, positioning itself to meet growing consumer demand effectively. The establishment of an Open Innovation Center in Tokyo is also indicative of Oishii's focus on research and development, allowing for continued innovation in its farming practices.

Despite a cooling trend in the vertical farming sector, Oishii's focused approach has allowed it to maintain momentum. The company has successfully adapted its business model to reach a broader consumer base, introducing new berry varieties and innovative packaging solutions aimed at enhancing freshness and reducing environmental impact. The recent launch of its Premium Preserves line exemplifies Oishii's strategy to expand its brand beyond fresh produce, tapping into new market segments.

The implications of this financing round extend beyond Oishii, highlighting a renewed interest in the vertical farming sector as companies seek to leverage technology to address food security and sustainability challenges. As Oishii continues to scale its operations and refine its Smart Farm model, it may set a precedent for other players in the industry, potentially revitalizing investment and innovation in the sector. The successful execution of Oishii's growth strategy could serve as a benchmark for future developments in indoor agriculture, shaping the landscape for years to come.
