Typhoon Dujuan kills at least four in Japan, leaves tens of thousands without power
At least four people killed in landslides, 22 injured, two missing in collapsed homes, and 1.6 million residents evacuated.
Mud flowing into homes. Entire hillsides coming down.
Mark
Four people dead, 45,000 without power, 1.6 million evacuated—those are big numbers. But what actually happened on the ground? What does a typhoon like this feel like?
Mimi
It's the rain that does the killing. Dujuan brought 832 millimeters in 48 hours to one island—that's not rain, that's a deluge. Mud slides into homes. Entire hillsides come down. People are trapped inside collapsed houses.
Luke
So we have four confirmed dead. But two people are still missing in Chiba, and another couple is missing in Yokosuka. Those aren't in the death count yet. How long do search operations typically continue?
Mimi
Days, sometimes weeks. But the longer someone is missing after a collapse, the less likely the outcome. The families are waiting.
Mark
The evacuation of 1.6 million people—was that effective? Did it prevent deaths?
Mimi
It's hard to say directly. The evacuations weren't mandatory, so compliance was probably uneven. But the fact that authorities issued them suggests they were taking the threat seriously. The real question is whether people actually left.
Luke
Right. We don't have numbers on how many of those 1.6 million actually evacuated. That's a gap in the reporting. We know the order was issued, but not the uptake.
Mark
And the climate angle—is this storm actually evidence of climate change, or just a bad typhoon?
Mimi
Scientists say warmer air holds more water, so storms intensify. This year has seen unusual rain and flooding globally. Dujuan fits a pattern, but one storm isn't proof of anything.
Luke
Exactly. The source says scientists link climate change to intensifying risk, but it doesn't quote any scientist directly. That's attribution without voice. We're told it's true, but we don't hear from the person saying it.
Mark
So what should people in Japan be watching for now?
Mimi
The next storm. This is late summer and early autumn—typhoon season. And if the pattern holds, the next one could be just as intense.
The Pulse
- Winds of 144km/h and record-shattering rainfall — 832mm in 48 hours on Oshima island — turned Typhoon Dujuan into one of the most destructive storms to strike the Tokyo region in recent memory.
- Landslides buried homes in Kanagawa and Chiba prefectures, killing at least four people and leaving two couples unaccounted for beneath collapsed structures as rescue teams continued searching.
- 45,000 households lost power in Chiba alone, 275 flights were cancelled across two major airlines, and major public events — including competitions at the Asian Games — were shut down mid-course.
- 1.6 million residents near Tokyo received evacuation orders on Monday, a number that reflects not just the storm's size but the acute vulnerability of one of the world's most populated urban corridors.
- As warnings were downgraded Tuesday morning and the typhoon moved away, scientists pointed to what the rainfall records confirm: storms like Dujuan are growing more intense, and Japan's late-summer seasons will only grow more dangerous.
Typhoon Dujuan swept through Japan's most densely populated region, killing at least four people and displacing 1.6 million more — a storm that arrived not merely as a weather event, but as a reminder of what a warming atmosphere increasingly demands of human societies. The landslides that buried homes in Kanagawa and Chiba, the record rainfall that shattered decades of measurement, and the flights cancelled and games suspended all speak to a familiar modern tension: the collision between the rhythms of ordinary life and the growing force of a destabilized climate. Japan has long lived in negotiation with powerful typhoons, but the terms of that negotiation are quietly, measurably changing.
Typhoon Dujuan tore through Japan with 144-kilometer-per-hour winds, killing at least four people, injuring 22, and sending rescue teams into collapsed homes in search of the missing. By Tuesday morning the storm had begun to move away from the archipelago, and authorities started lifting their most urgent warnings — but the damage it left behind was still being counted.
The deadliest toll came through landslides. In Yokosuka, south of Tokyo, mud overwhelmed a residential home and killed a woman in her 60s; police were still searching for a couple in their 70s believed buried nearby. In neighboring Chiba prefecture, three more deaths were confirmed from separate landslides, with two additional people unaccounted for after their homes collapsed. Chiba also saw 45,000 households lose electricity as the storm passed.
The disruption spread well beyond the death toll. Japan Airlines and All Nippon Airways together cancelled 275 flights, stranding travelers across the country. More than 1.6 million residents in and around Tokyo received evacuation orders — non-mandatory, but a signal of how seriously authorities read the threat. The Asian Games and a major Tokyo video game trade fair both suspended events mid-schedule.
The rainfall was the kind meteorologists mark in their records. Oshima island, 120 kilometers south of central Tokyo, received 832 millimeters of rain in just 48 hours — more than double its entire September average. Tokyo's Edogawa ward broke its own 24-hour rainfall record. Scientists note that a warmer atmosphere holds more moisture, making landfalling storms capable of releasing water at volumes that were once statistical outliers. Japan has always lived with powerful typhoons, but the data from storms like Dujuan suggests the baseline is shifting — and the country's preparations will need to shift with it.
Typhoon Dujuan swept across Japan with violent winds of 144 kilometers per hour, leaving at least four people dead and 22 injured in its wake. By Tuesday morning, as the storm moved away from the archipelago, authorities began downgrading their most urgent warnings—heavy rain alerts and landslide advisories that had dominated the previous day. But the damage was already done. Tens of thousands of households near Tokyo remained without power, rescue teams were still searching for missing people in collapsed homes, and the full scope of destruction was still being assessed.
The storm's deadliest impact came through landslides triggered by torrential rain. In Yokosuka, a city in Kanagawa prefecture just south of Tokyo, mud flowing into a residential home killed a woman in her 60s. Police and firefighters were searching for a couple in their 70s believed to be missing in the same area. Across the border in Chiba prefecture, three additional deaths were confirmed from a series of landslides, with two more people unaccounted for after their homes collapsed. The scale of displacement was staggering: 45,000 households in Chiba alone had no electricity on Tuesday morning.
The typhoon's reach extended far beyond the immediate death toll. Japan Airlines cancelled 135 flights while All Nippon Airways scrapped 140 more, stranding travelers and disrupting the country's transportation network. More than 1.6 million residents in and around Tokyo received evacuation orders on Monday—though these were not mandatory, they reflected the severity of the threat authorities anticipated. The storm also forced early closures of major events, including some competitions at the Asian Games and one of the world's largest video game trade fairs held in Tokyo.
The rainfall was extraordinary. Oshima, an island roughly 120 kilometers south of central Tokyo, received 832 millimeters of rain over just 48 hours—more than double what the island typically sees throughout the entire month of September. In Tokyo's Edogawa ward, the city recorded 282.5 millimeters of rain in a single 24-hour period, breaking the previous record for that measurement. These were not merely heavy storms; they were statistical outliers, the kind of weather events that meteorologists track because they signal something shifting in the climate system itself.
Scientists have long warned that human-driven climate change intensifies the danger posed by tropical cyclones, particularly through heavy rainfall. A warmer atmosphere holds more moisture, which means storms that reach land can dump unprecedented amounts of water in short periods. Typhoon Dujuan arrived in a year already marked by unusually intense rain, flooding, and tropical cyclones across multiple continents—from East Asia to North America to Europe. Japan, which regularly experiences strong typhoons in late summer and early autumn, is becoming a testing ground for what intensifying storms look like in practice. The question now is not whether such storms will return, but how quickly, and what preparations the country can make for the next one.
