As Typhoon Dujuan batters Japan's Pacific coast, nearly two million people face evacuation orders while super El Niño conditions fuel the storm's intensity. The massive system is bringing torrential rains and dangerous winds to several coastal prefectures, threatening infrastructure and local communities. Emergency services are on high alert as the storm makes landfall during a period of significant seasonal activity. Residents are being urged to follow local government instructions immediately to ensure safety. This meteorological event highlights the growing volatility of weather patterns in the region.
How much impact has Typhoon Dujuan caused across Japan?
Typhoon Dujuan has caused significant logistical and physical disruption across the Japanese archipelago, affecting millions of residents and travelers. The storm, which is the 25th typhoon to hit Japan this year, has struck during a five-day national holiday, compounding the difficulty of emergency management and public movement. The timing of the storm means that the disruption to daily life is amplified by the presence of citizens traveling or celebrating during the holiday period.
The most immediate large-scale impact is the evacuation of almost two million people. While the Japan Meteorological Agency (JMA) has downgraded several warnings in various prefectures, the threat remains critical in specific locations. For instance, Oshima Town remains under a high-level danger to life warning. Furthermore, the storm has crippled infrastructure, with more than 50,000 people losing power due to high winds. The transport sector has faced massive delays, characterized by hundreds of cancelled flights and the suspension of major rail services, leaving many travelers stranded during the holiday window.
Disruption to public events and holidays
Because the typhoon coincided with a five-day holiday period, the economic and social impact extended to the entertainment and technology sectors. Major scheduled events were forced to cancel their programmes to ensure public safety. Notably, the Rock in Japan music festival had to cancel its Monday concert schedule. Similarly, the Tokyo Game Show, a prominent international video game convention, was forced to cancel its Monday programming. These cancellations highlight how extreme weather events can disrupt not only daily life but also significant commercial and cultural gatherings, impacting both local businesses and international visitors.
What are the specific casualties and damage reports?
Emergency services in various prefectures have reported several life-threatening incidents involving landslides and structural damage. While the full extent of the damage may not be fully assessed until Tuesday, several harrowing accounts have emerged from local fire departments regarding the direct impact on residents and workers.
- Oshima and surrounding areas: Authorities have maintained high-level warnings due to the persistent threat to life, as the storm's intensity continues to pose risks to coastal and mountainous regions.
- Chiba Prefecture: The Sodegaura City Fire Department reported a rescue operation in which a man in his 50s was saved after becoming trapped. The worker was clearing debris at a landslide site when he fell into a bamboo thicket along with heavy machinery; he was subsequently transported to a hospital.
- Kanagawa Prefecture: Firefighters received reports of residential properties being crushed by the force of landslides, illustrating the destructive power of the saturated ground and heavy rainfall.
- Residential fatalities: The Yokosuka City Fire Department informed the BBC that a woman in her 60s may have been swept away by the storm and is feared to have been buried alive in her home.
These individual reports underscore the immediate danger posed by the typhoon's combination of high winds and the resulting landslide risks in hilly or forested areas.
Which areas remain under high-level weather warnings?
Although the Japan Meteorological Agency has begun lifting or downgrading several level three (heavy rain) and level four (landslide) warnings, certain areas remain in a state of high alert. The JMA continues to monitor the storm as it travels north along Japan's Pacific coast, and the situation remains fluid as the system moves.
Currently, level four landslide warnings remain active in the following locations:
- Shinagawa Ward
- Toshima Village
- Niijima Village
Authorities continue to urge the public to remain vigilant and closely monitor official weather updates as the typhoon progresses. The movement of the storm along the coast means that even as some areas see a reduction in intensity, others may face new risks as the system moves northward. The JMA's warnings serve as a critical guide for residents in these high-risk zones to take necessary precautions against potential landslides and flooding.
What role do El Niño and climate change play in this storm?
The intensity of Typhoon Dujuan is being driven by a combination of natural weather phenomena and broader climatic trends. Specifically, a "super El Niño" has warmed the ocean temperatures, providing the thermal energy necessary to fuel the formation and intensification of such powerful storms. This warming of the ocean acts as high-octane fuel for the typhoon's engine.
While El Niño is a natural phenomenon that brings warmer water to parts of the tropical Pacific, its influence on typhoon patterns is complex. It does not necessarily increase the total number of typhoons globally, but it significantly influences their trajectory, strength, and the specific regions they impact. In some years, El Niño events can increase the exposure of Japan to more powerful typhoons, potentially leading to more frequent or severe direct hits.
The link between rising temperatures and storm intensity
Scientific research suggests a distinction between the frequency of storms and their individual intensity. While climate change is not thought to be increasing the total number of storms globally—and may even decrease them in certain regions—it is expected to make the storms that do form more destructive. As global temperatures rise, two primary mechanisms enhance typhoon power:
- Increased Energy: Warmer ocean waters provide more fuel for storms, leading to higher sustained wind speeds. Dujuan, for example, has recorded sustained winds of 130km/h (80.8mph) and gusts of 194km/h.
- Increased Moisture: A warmer atmosphere has a higher capacity to hold moisture, which translates to more intense and heavy rainfall. This increased moisture contributes directly to the landslide risks observed in prefectures like Kanagawa and Chiba.
This dual impact of higher wind speeds and heavier precipitation increases the risk of both structural damage and catastrophic landslides, as seen during the current event. The interaction between the super El Niño and these rising baseline temperatures creates a highly volatile environment for tropical cyclones.
Political response and international implications
The severity of the typhoon has also impacted high-level political scheduling. Japan's Prime Minister Sanae Takaichi has reportedly delayed her trip to the United States this week to monitor the effects of the typhoon. This decision comes at a critical time, as she had been due in New York on Tuesday to meet with US President Donald Trump and speak at the UN General Assembly. The delay highlights the priority given to domestic crisis management and the need for direct oversight of the disaster response efforts within Japan.
