Sano City authorities lifted a Level 5 emergency safety measure on Saturday at 5 p.m. [1].
The lifting of this alert marks the end of the most critical phase of a weather emergency in Tochigi Prefecture. Level 5 alerts, the highest in the Japanese warning system, signal that danger is imminent and residents must take immediate action to save their lives.
The emergency measures were originally implemented due to heavy rainfall that threatened the region. Officials said they decided to rescind the order after the intensity of the rain diminished [3].
The alert affected seven specific districts within Sano City [2]. These areas included Kami-Haneda-machi, Shimo-Haneda-machi, Namiki-cho, Mendori-cho, Konaka-cho, Murakami-cho, and Takahashi-cho [2].
Despite the lifting of the Level 5 alert, local officials continue to urge caution. The risk of landslides remains high due to loosened soil from the saturation of the ground. Additionally, residents are warned to stay away from rivers that may still be swollen or experiencing high water levels [3].
Local government agencies and disaster management teams remain on standby to monitor the stability of the terrain. The transition from an emergency safety phase to a recovery and monitoring phase is critical for preventing secondary disasters, such as slope failures, which often occur after the rain has stopped.
“Sano City authorities lifted a Level 5 emergency safety measure on Saturday at 5 p.m.”
The rescinding of a Level 5 alert indicates that the immediate threat to life from flooding or landslides has passed, but the environmental risk persists. In Japan's disaster management framework, the shift from 'Emergency Safety' back to lower alert levels often coincides with a high risk of secondary landslides because the soil remains unstable long after the rain ceases.
