Typhoon 6 is bringing record rainfall and landslides to Japan as the storm approaches the archipelago with a strong wind zone [1, 2].
The storm's impact threatens critical infrastructure and public safety across two major regions, risking further slope collapses and widespread flooding in densely populated areas.
In Kyushu, the situation has already become critical. In Nagasaki Prefecture, rainfall exceeded 500 mm over a three-day period [3]. The heavy precipitation led to significant structural damage in the region. In Sasebo City, a mountain behind a residential home collapsed, leaving vehicles buried under debris [3].
While Kyushu has faced the most immediate devastation, officials are now turning their attention toward the Kanto region. Forecasts indicate that the Tokyo metropolitan area may experience warning-level heavy rain [1, 2]. Some reports suggest the region could see record-breaking wind and rain, necessitating high alert for potential disasters [4].
Meteorologists said that the peak of the rainfall was expected on the morning of June 3 [5]. The intensity of the weather was described as so severe that residents might hesitate to leave their homes upon opening their doors [5].
Local authorities in Nagasaki and the surrounding areas continue to monitor slope stability as the saturated ground increases the risk of further landslides [3]. Residents in the path of the storm are urged to follow evacuation orders and stay clear of steep terrain.
“In Nagasaki, rainfall exceeded 500 mm over a three-day period.”
The simultaneous threat to both Kyushu and Kanto suggests a wide-reaching weather system that strains emergency response resources. The record rainfall in Nagasaki indicates an extreme saturation of the soil, which often leads to secondary landslides even after the primary storm system has passed.
