Water shortages and dam restrictions in Japan

Overview

Japan is experiencing significant water shortages across multiple regions due to low rainfall and insufficient snowfall.

In early August, the Miboro Dam in Gifu Prefecture saw water levels drop to approximately 30% of normal volume, threatening irrigation for 12,000 hectares across six cities in Toyama. Authorities monitored the Shō River basin to determine if water withdrawal restrictions, which have not been implemented in this area since 1994, would be necessary.

By mid-August, the drought impacted additional areas. In Ishikawa Prefecture, the Tedorigawa Dam’s storage rate fell to 24%, prompting restrictions on nighttime agricultural water use. Simultaneously, in the Shikoku region, the Sakeura Dam in Kochi Prefecture reached a storage rate of 36.8%, leading the Yoshino River system water use council to initiate a third round of intake restrictions. These measures included a 50% reduction in water supplies to Kagawa and an 18% reduction to Tokushima.
