## Information Communication Company Hokutsu Co., Ltd.
Hokutsu Co., Ltd. (Kanazawa City, Ishikawa Prefecture) is developing 'Mizu-mawari-kun,' a labor-saving system for paddy field water management. While many agricultural tasks have achieved labor savings through mechanization and automation, water management still often relies on manual labor, including long hours under the scorching sun. 'Mizu-mawari-kun' allows easy and accurate water management for extensive and numerous fields. This reduces the time required for water management, improves labor productivity, enhances quality, increases yield, and realizes sustainable agriculture.
## Background of the Dream
Hilly and mountainous areas in Japan account for about 40% of the total cultivated land, farm households, and agricultural output. These paddy fields play a huge role in national food production and land preservation. However, issues like labor shortages and increasing abandoned farmland are more severe than in flatlands. Conditions such as water rights, location, weather, and communication environments are extremely unfavorable. We aim to address these disparities by introducing new automated water management techniques suitable for hilly and mountainous regions, eliminating the gap between these areas and flatlands.
## Products and Technology
- **Mizu-mawari-kun (for pressurized pipelines):** An automated water supply system that can be controlled remotely.
- **Mizu-mawari Gate-kun (for open channels):** A system designed to manage water flow in open irrigation ditches.
By utilizing IoT sensors and wireless communication, farmers can monitor water levels and control water gates from their smartphones or computers, significantly reducing the need for physical site visits.
