Legmin Inc.
Saitama startup founded in 2018 that builds a license-free LiDAR-guided crawler robot for spraying pesticides on field vegetables and offers spraying services.
Legmin Inc. is a Japanese agricultural technology company based in Fukaya, Saitama Prefecture, that develops robots for pesticide spraying in open-field vegetable farming. The company was founded in May 2018 and is led by Representative Director and CEO Yoshihiro Noge. Its business covers research and development of agricultural robots and IoT devices, pesticide spraying services, and contract development of robots and systems. The company reports 12 employees, plus 4 at its affiliate Legmin Agri Service, which handles field operations.
Legmin's main product is a battery-powered pesticide spraying robot on a crawler undercarriage that can be operated without a special licence or qualification. It carries a 300 L tank; at an application rate of 150 L per tan (about 0.1 ha), one fill covers roughly 0.2 ha. The battery supports up to 8 hours of operation. The robot uses LiDAR to build a 3D point cloud and follow crop furrows autonomously, adjusting to curves, slopes and height changes; this row-detection driving method is covered by Japanese Patent No. 6700500. Operators control it through a Bluetooth controller or remotely over outdoor Wi-Fi. The crawler has a step-absorption mechanism, and its ground pressure is described as comparable to a person walking. Interchangeable nozzle booms match different crops and row widths, and the company reports use on leek, cabbage and broccoli. Hardware, circuits and software are developed in-house, and a companion app records pesticide quantity, dilution ratio, field data and work history.
Alongside equipment sales, Legmin offers pesticide spraying as an outsourced service. In May 2026 it signed a demonstration contract with Sanin Sanso Kogyo Co., Ltd. for a spraying BPO service, and in September 2026 it received investment from Meek Inc. and began collaborating on IoT-enabled agricultural robots. Investors listed by the company include INCUBATE FUND, Kitanodaichi Fund, Fukaya City, PE&HR, Resona Capital, Musashino Bank, AgVenture Lab, Shibusawa MIX and Honeycomb Investment.
