Paddy Watch trialed in Niigata area ― One of Japan’s major rice-producing regions ―
Niigata is designated as a
strategic district for developing
more competitive agro-business
to help stimulate rural Japan.
460 hectares of rice paddies and 300 sensors installed in paddies.
Collaboration with Niigata city

In collaboration with Japan’s agricultural ministry,
Paddy Watch trials were carried out with 43 prefectures.
Collaboration with central government

Introduction of LPWA in fiscal 2017
3G/LTE
LPWA modules
Planned introduction of Low-Power Wide-Area (LPWA) network
and convergence via gateways will further reduce system costs
