Shimoda City officials ordered city-wide evacuations and suspended railway services after Typhoon No. 7 triggered a level-4 landslide-danger warning [1].

The emergency measures reflect the high risk of soil instability and flash flooding in Shizuoka Prefecture, where intense rainfall can lead to rapid, life-threatening landslides.

Rain intensity peaked around 4 a.m. JST on Sept. 3, 2024 [1]. The Japan Meteorological Agency issued the level-4 warning at 6:36 a.m. JST that same day [2]. While precipitation briefly stopped around 7 a.m. JST, weather officials said that rain would intensify again [1].

Local authorities responded by opening six evacuation shelters across Shimoda City [1]. By 11 a.m. JST, four households consisting of six people had evacuated to these facilities [1]. The city-wide order was designed to move residents out of high-risk zones before the evening's expected heavy rainfall.

Transportation in the region was heavily impacted by the storm. The Izu Kyuko Railway suspended all services for the entire day [1]. The suspension included the area around Shimoda Station, effectively cutting off rail access to the city to ensure passenger safety during the peak of the storm.

These warnings are part of a tiered system used by Japanese meteorological authorities to signal increasing levels of danger. A level-4 warning indicates that the risk of a disaster is imminent, and that residents should prioritize immediate evacuation to secure locations [1].

“Shimoda City officials ordered city-wide evacuations and suspended railway services.”

The coordination between the Japan Meteorological Agency and local transit providers like Izu Kyuko Railway demonstrates Japan's integrated disaster mitigation strategy. By suspending transport and issuing high-level warnings before peak rainfall, authorities aim to minimize casualties in mountainous regions prone to landslides during typhoon season.
