Farmnote Color AI Cattle Wearable and Farmnote Cloud

Farmnote Inc. is a Japanese agtech company founded on 29 November 2013 and headquartered in Obihiro, Hokkaido, with an office in Tokyo. It develops digital tools for dairy and beef cattle farms that struggle to detect heat, illness and calving in time as herds grow and labour becomes scarce.

Farmnote Color is a belt-worn sensor that tracks each animal's activity and rumination; AI learns individual patterns and flags estrus with the best insemination timing, reduced activity, difficulty standing in fattening cattle and calving signs within 24 hours. A barn gateway relays data over LTE to the Farmnote Color app and Farmnote Cloud, the company's herd management system, which lists cows that meet set conditions and organises records automatically. The company reports cumulative adoption by about 1,900 farms.

• Estrus detection: alerts with the optimal insemination window for each cow.
• Health monitoring: flags cows with reduced activity or changed rumination.
• Calving alerts: warns of calving signs within 24 hours before delivery.
• Standing-difficulty alerts: helps prevent falls in fattening cattle.
• Air Gateway: relays data from up to 100 sensors over LTE.
• Farmnote Cloud: herd records, condition-based cow lists and automatic reproduction KPIs.

• Dairy farms and milk collection cooperatives improving conception rates with automated heat detection.
• Beef fattening farms reducing losses from falls and late-detected illness.
• Dairy processors offering wearable monitoring to supplier farms to stabilise milk volumes.

• Detects heat automatically and suggests insemination timing, reducing missed breeding cycles.
• Flags health problems and calving earlier through changes in activity and rumination.
• Keeps upfront costs low through a subscription with warranty, plus a 3-month trial plan.
• Long-life hardware: the sensor battery lasts about five years and one gateway serves up to 100 devices.

Dairy and beef farms are growing in herd size while skilled labour becomes harder to find, making automated heat and health detection a standard tool. Vietnam is expanding its dairy herd and large dairy farms already use identification chips and herd data, which creates demand for wearable monitoring among mid-sized farms and cooperatives.

Founded in November 2013, headquartered in Obihiro, Hokkaido, led by CEO Shinya Kobayashi, with about 60 employees and capital of JPY 900m according to its English site. Other offerings include Farmnote Compass analytics, Farmnote Gene genetic testing and Wagyu embryo supply. Group company Farmnote Dairy Platform won the Nikkei Award at GenAI/SUM 2026 IMPACT PITCH.
