Japan Weather Alert: Blizzards, Wildfires, and Earthquake Updates for Expats

Japan faces multiple disaster challenges: severe blizzards hitting Hokkaido through February 9, an uncontrolled wildfire in Chichibu, drought conditions causing low reservoir levels, and continued earthquake monitoring.

Key Points

  • Severe blizzards affect Hokkaido and Sea of Japan areas February 7-9.
  • Chichibu wildfire continues spreading; drought causes historically low reservoir levels.
  • Download NHK World app and enable emergency notifications for English alerts.
  • Maintain earthquake preparedness kits despite stable Nankai Trough assessment.
Foreign residents across Japan should stay alert as the country faces multiple natural disaster challenges this week, including severe winter storms, ongoing wildfires, and continued earthquake activity. Understanding these risks and knowing how to respond is essential for anyone living in Japan. According to NHK, a rapidly developing low-pressure system is bringing dangerous blizzard conditions to Hokkaido, with the Japan Meteorological Agency (JMA) warning of significant transportation disruptions. The severe weather is expected to continue from Saturday, February 7 through Monday, February 9, affecting primarily the Sea of Japan side of the country. However, the Pacific side will also see unusual snowfall accumulation during this period. The JMA is urging residents to exercise extreme caution regarding traffic conditions, as reduced visibility and snow accumulation can make travel hazardous. Expats planning travel during this period should monitor local weather updates closely and consider postponing non-essential trips. In Saitama Prefecture, firefighters continue battling a stubborn wildfire that began on February 4 in the mountainous Chichibu area. Despite ongoing firefighting efforts, the blaze remains uncontrolled and continues spreading through the forested region. According to NHK reports, firefighting operations were suspended at sunset on February 6 due to safety concerns and are scheduled to resume at dawn on February 7. The persistence of this fire highlights a growing concern across the Pacific side of Japan: severe drought conditions. The lack of rainfall on the Pacific side has created critically low water levels in several reservoirs serving the Kanto region. Some dams have reached historically low storage rates, according to NHK. This drought not only increases wildfire risk but also raises concerns about potential water restrictions in the coming weeks. Expats living in Tokyo and surrounding areas should be prepared for possible water conservation measures and should monitor announcements from local authorities regarding water usage guidelines. Earthquake activity continues as expected in this seismically active nation. On February 7 at 12:58 AM, a magnitude earthquake registering intensity 3 on the Japanese seismic scale struck Tochigi, Gunma, and Saitama prefectures. The JMA confirmed no tsunami risk from this event. While intensity 3 earthquakes cause noticeable shaking, they typically do not result in damage to well-constructed buildings. More significantly, the JMA's regular Nankai Trough evaluation committee met and released their routine assessment, stating that "no particular changes have been observed" regarding the potential for a major earthquake along the Nankai Trough. This undersea trough, running along Japan's Pacific coast, is capable of producing devastating magnitude 8-9 earthquakes. While the current assessment provides some reassurance, the committee's ongoing monitoring underscores the ever-present seismic risk. Expats should maintain their earthquake preparedness regardless of these assessments, keeping emergency kits stocked and evacuation plans current. For foreign residents, these concurrent natural disaster risks emphasize the importance of comprehensive preparedness. Download the NHK World app and enable emergency notifications to receive alerts in English. Register with your embassy or consulate, ensure your emergency kit includes supplies for at least three days, and familiarize yourself with evacuation routes from your home and workplace. The combination of severe winter weather, wildfire risk from drought conditions, and ongoing seismic activity demonstrates why Japan maintains such robust disaster preparedness systems. As an expat, integrating into these systems and staying informed through official channels is not just advisable—it's essential for your safety and peace of mind while living in Japan.
