This page outlines Japan's Water Resources Development Basic Plans (Full Plans) managed by the Ministry of Land, Infrastructure, Transport and Tourism. Seven river systems—Tone, Ara, Toyokawa, Kiso, Yodo, Yoshino, and Chikugo—are designated for comprehensive water resource development and rational utilization. These areas cover only 17% of Japan's land but concentrate about 50% of the population and industrial activity. The plans address water demand forecasts and infrastructure development. Responding to recent crises including droughts and aging facilities, the ministry is implementing fundamental revisions toward risk-management-oriented water supply stability.
