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
