Croft GrowPilot + Asai Japan: AI Tomato Greenhouses Oct 2026

Crop-responsive AI crosses into Japan’s commercial tomato belt. On October 1, 2026, HortiDaily detailed a memorandum of understanding between Croft Agricultural Corporation (Korea; GrowPilot / GrowBot) and Asai Nursery in Mie Prefecture.

Asai at a glance

• 119-year family grower; tomatoes in Mie for 18 years
• Five tomato greenhouses across 13 hectares, >1,000 tons cherry tomatoes/year
• Existing stack: Priva climate/data; AgriD joint venture with DENSO since 2018

What Croft brings

GrowBot scans and phenotypes plants directly; GrowPilot turns that feedback into environmental decisions while remaining sensor-agnostic so Asai can keep Priva hardware. Site surveys are done; proprietary sensor installs are planned for October; AI integration continues alongside greenhouse renovations. The goal is one dashboard across all five houses—yield/quality up, crop-registration time down—without a proportional headcount jump.

Context

Croft (founded 2022) cites 30+ Korean growers and a 45% operational-efficiency gain at JE Farms after adoption. Asai is its first large commercial grower partnership outside Korea and first Japanese market move.

Why Japan is the scale test

Asai is expanding into a Hokkaido greenhouse and exploring avocado research in Okinawa plus wasabi, Japanese pear, and strawberries. CEO Yuichiro Asai describes the business as “a production business anchored in R&D.” Croft CEO Hee Kyung Ryoo calls Japan one of the most technologically advanced CEA markets and the place to prove multi-hectare, multi-house dashboard control. The MOU is framed as an equal partnership: Asai brings commercial greenhouses and grower expertise; Croft brings GrowPilot automation across any sensor set.

Labor math Croft is selling

Rather than cutting headcount, Croft argues expert decisions should live in the system so five sites can scale without a matching jump in specialized staff—crop registration time is an explicit KPI alongside yield and quality.

Croft cites JE Farms (North Jeolla cherry tomatoes) as a reference deployment with a 45% operational-efficiency gain after adoption without hiring more crop-registration staff. Extending that playbook to Asai’s five houses is the explicit next proof point—not a guarantee of the same percentage in Japan.
