Hiroki Tomiyasu, a farmer in Hokkaido, Japan, is using AI tools like ChatGPT and OpenAI Codex to run his large 100-hectare farm successfully. He grows broccoli, pumpkins, green onions, and soybeans. Tomiyasu had no background in farming or engineering. He worked as a public servant before switching to agriculture.
He joined efforts to restore abandoned farmland and taught himself how to manage crops and machinery. Running a big farm is tough and expensive. Instead of buying costly ready-made technology, he used AI to build his own solutions.
With ChatGPT and Codex, Tomiyasu created many useful tools. These include an automated system for greenhouse vents that opens and closes automatically, a satellite-based field monitoring platform, and photo-generated electrical wiring diagrams. He also built an integrated farm management system that connects work schedules, daily records, materials, and sensor data.
These smart tools help him solve crop problems, learn new techniques, check for diseases, and make better decisions quickly. He says it feels like having a talented engineer always available. His story shows how ordinary people can use AI to overcome big challenges without large budgets or expert teams.
Tomiyasu’s success is inspiring many. It highlights the power of AI in modern farming and encourages others to try new technologies for better and smarter work.
