An Innovative Approach to Water Resource Management

Yachiyo Engineering Co., based in Taito-ku, Tokyo, showcased its groundbreaking solution, Water Map, at the 5th Business Forum of the Japan Conference for the Realization of the 2030 Biodiversity Framework (J-GBF) held on December 2, 2025. This forum provided a platform for businesses to discuss biodiversity challenges and solutions, highlighting the importance of sustainable practices in today’s corporate landscape.

What is the Water Map?

The Water Map is a revolutionary solution that visualizes the quantity and risk of water resources at a river basin level. By employing weather data alongside land-use information, Yachiyo Engineering calculates various data points, including evaporation, surface runoff, and underground infiltration. This tool is especially useful for assessing the water resource holding capacity of areas such as forests and rice paddies. Additionally, it supports existing activity evaluations and provides insights essential for achieving nature-positive initiatives.

Key Features:

1. Comprehensive Water Resource Evaluation Across Japan: The tool enhances assessments by considering weather patterns and land-use types to evaluate underground water infiltration.
2. Evaluation of Water Conservation Initiatives: Water holding capacities can be evaluated flexibly to support corporate conservation efforts involving forests and rice paddies.
3. Cost-Effective Evaluation Compared to Traditional Methods: By visualizing water balance across Japan, evaluations can be conducted swiftly and at a reduced cost.

The Water Map has been recognized for its innovation, notably receiving the Excellence Award at the 7th EcoPro Award, organized by the Sustainable Management Promotion Organization.
