Foreign residents in Japan received a stark reminder of the country's seismic reality on November 3rd, as Kagoshima Prefecture experienced multiple earthquakes within hours, while communities across the nation continue ramping up disaster preparedness efforts. According to NHK, a series of earthquakes struck the Satsuma region of Kagoshima Prefecture on the evening of November 3rd, with Kirishima City recording tremors of magnitude 4 and 3 on the Japanese seismic intensity scale. The first significant quake occurred at 6:50 PM, registering magnitude 3, followed by a stronger magnitude 4 earthquake at 7:18 PM. The Japan Meteorological Agency confirmed that no tsunami warnings were issued for any of these events. The Meteorological Agency has urged residents in the affected areas to remain vigilant for continued seismic activity in the coming days. This cluster of earthquakes serves as a timely reminder for all residents of Japan, including the expatriate community, to review their emergency preparedness plans and ensure they have adequate supplies and evacuation routes identified. For expats unfamiliar with Japan's earthquake intensity scale, magnitude 4 represents "strong" shaking that most people will notice, causing hanging objects to swing considerably and dishes in cupboards to rattle. While not typically causing structural damage to modern buildings, such tremors can be unsettling, particularly for those experiencing them for the first time. Concurrent with the Kagoshima seismic activity, communities in high-risk areas are intensifying their disaster preparedness training. According to NHK, Kushimoto Town in Wakayama Prefecture conducted evacuation drills on November 3rd specifically focused on the anticipated Nankai Trough megaquake scenario. This massive earthquake, which seismologists warn could occur at any time, is projected to generate tsunami waves that would reach Kushimoto's coastline within just minutes of the initial tremor. The Nankai Trough, a submarine trough located off Japan's Pacific coast, has historically produced devastating earthquakes approximately every 100 to 150 years. The last major event occurred in 1946, making the region statistically overdue for another significant seismic event. Government projections estimate that a Nankai Trough megaquake could affect a vast area from the Kanto region through Kyushu, potentially impacting millions of residents, including many of Japan's expatriate communities concentrated in major urban centers. The Kushimoto evacuation drill emphasized rapid response protocols, with participants practicing immediate evacuation to higher ground upon receiving earthquake early warnings. Such drills are becoming increasingly common across Japan's Pacific coastal regions, reflecting growing awareness of tsunami risks. For foreign residents, understanding Japan's multi-layered emergency alert system is crucial. Smartphones equipped with Japanese SIM cards automatically receive emergency alerts through the J-ALERT system, which provides warnings for earthquakes, tsunamis, and other disasters. Expats should ensure their devices are configured to receive these alerts and familiarize themselves with the distinctive alarm sound. The recent Kagoshima earthquakes and ongoing preparedness training underscore several practical steps expats should take immediately. First, assemble an emergency kit containing at least three days of water, non-perishable food, a flashlight, battery-powered radio, first aid supplies, and copies of important documents. Second, identify evacuation routes from your home and workplace, noting the locations of designated evacuation centers, which are typically marked with green signs featuring a running figure. Third, register with your embassy and ensure emergency contacts have your current information. Japan's disaster preparedness infrastructure is among the world's most advanced, but personal readiness remains essential. Local ward offices and community centers regularly offer disaster preparedness workshops, often with English support in areas with significant foreign populations. Taking advantage of these resources can prove invaluable during an actual emergency. While the recent Kagoshima earthquakes caused no reported injuries or significant damage, they serve as an important reminder that seismic activity can occur anywhere in Japan at any time, making preparedness not optional but essential for all residents.
