Japan braces for dual typhoon threat as Higos, Mekkhala approach
Over 2 million people evacuated across 13 prefectures due to heavy rainfall and typhoon threats; at least one landslide occurred in Kyoto Prefecture.
More than 2 million people displaced as the ground itself becomes unstable
Mark
Why are two typhoons arriving at the same time such a particular danger? Couldn't Japan handle them separately?
Mimi
It's the timing and the ground. By Friday, some areas had already received 600 millimeters of rain in four days. The soil is saturated. When Higos arrives and Mekkhala is still moving through, you're not getting two separate events—you're getting continuous, overlapping rainfall on terrain that can't absorb any more water.
Mark
So the evacuation orders for 2 million people—was that precautionary, or had damage already occurred?
Mimi
Both. A landslide had already happened in Kyoto by Friday morning, which triggered the highest emergency alert. The evacuations were partly response to what was already happening and partly preparation for what was coming. They were moving people out of the path before Saturday.
Mark
The forecasts mention 300 millimeters more rain in Tokai by Saturday noon. In context, does that sound manageable or dire?
Mimi
In isolation, 300 millimeters is a heavy rainfall event. But it's arriving after weeks of wet weather and on top of ground that's already waterlogged. The agency's language—"remain alert for landslides and flooding"—suggests they expected both, not just the possibility of them.
Mark
What happens to these typhoons after they make landfall?
Mimi
They weaken into extratropical cyclones, which sounds like relief but isn't quite. They lose the organized structure of a typhoon, but they still bring rain and wind. The danger shifts from the storm itself to the secondary effects—flooding, landslides, infrastructure damage from sustained wet conditions.
Le Pouls
- Two typhoons are converging on Japan simultaneously — Higos from the Pacific and Mekkhala tracking toward the densely populated Kanto region — a rare and dangerous pairing.
- Over 2 million people have already been evacuated across 13 prefectures, and a level-5 emergency alert — the highest possible — was triggered in Kyoto after a landslide struck in the early hours of Friday.
- Some areas have absorbed 600 millimeters of rain in just four days, leaving soil saturated and rivers swollen well before either typhoon makes full landfall.
- Authorities warn that even as both storms weaken into extratropical cyclones, they will continue driving heavy rainfall — up to 300mm more for the Tokai region alone — onto already overwhelmed ground.
- The critical window is the next 24 hours: whether the evacuations, the warnings, and the preparations prove sufficient will only become clear as the storms move through.
Twice in the span of a single weekend, Japan finds itself in the path of nature's full force — two typhoons arriving nearly in tandem, as if the sea and sky had conspired together. Millions have already left their homes across thirteen prefectures, and the earth in Kyoto has already given way in at least one landslide, a reminder that the danger does not wait for landfall. What meteorologists fear most is not the storms themselves, but the ground beneath them: soil already holding more water than it can bear, rivers already swollen, a landscape primed for catastrophe before the worst has even arrived.
Japan's meteorological agency issued urgent warnings Friday as two typhoons bore down on the country nearly simultaneously. Typhoon Higos was approaching from the Pacific, set to make landfall Saturday, while Typhoon Mekkhala was already threading through the southwestern islands and angling toward the Kanto region. The dual arrival came as heavy rain was already falling across much of the country, pushing conditions toward the edge of catastrophe.
The displacement had already begun on a massive scale. More than 2 million people across 13 prefectures in the Kinki and Kyushu regions were under evacuation orders by Friday morning. In Seika, Kyoto Prefecture, a landslide struck in the early hours of the day, prompting authorities to issue a level-5 emergency alert — the highest on the scale. The ground was already failing before the storms had fully arrived.
The rainfall figures from the preceding days told the story of what the region had already absorbed. Goto in Nagasaki Prefecture recorded 600 millimeters between Tuesday and Friday morning. Aso in Kumamoto and Ureshino in Saga each exceeded 500 millimeters. These were totals that saturate soil, destabilize slopes, and leave rivers with nowhere left to go.
Meteorologists expected both typhoons to weaken as they moved inland, but cautioned that the transition to extratropical cyclones would bring no real relief. The storms would continue producing significant rainfall through Saturday — up to 300 millimeters more for the Tokai region, and up to 150 millimeters for Kanto-Koshin. Arriving on top of already-saturated ground, these were not minor additions. The agency urged continued vigilance for landslides and flooding, and the next 24 hours would reveal whether the warnings had come early enough.
Japan's meteorological agency issued an urgent warning on Friday as the country braced for the arrival of two separate typhoons within hours of each other. Typhoon Higos was bearing down from the Pacific, expected to make landfall on Saturday, while Typhoon Mekkhala was already moving through the southwestern islands and tracking toward the densely populated Kanto region. The dual threat came as heavy rain was already falling across western and eastern Japan, creating conditions that authorities feared could turn catastrophic.
By Friday morning, the scale of displacement was already staggering. More than 2 million people across 13 prefectures in the Kinki and Kyushu regions had been placed under evacuation orders. In Seika, a town in Kyoto Prefecture, authorities issued the highest level of emergency alert—level 5—after a landslide tore through the area in the early hours of Friday. The ground itself was becoming unstable, and worse was coming.
The rainfall totals from the preceding days illustrated the intensity of what the region had already endured. Goto, in Nagasaki Prefecture, had received 600 millimeters of rain between Tuesday and Friday morning alone. Aso in Kumamoto Prefecture and Ureshino in Saga Prefecture each recorded more than 500 millimeters. These were not ordinary storms; they were the kind of deluges that saturate soil, swell rivers, and set the stage for disaster.
As of mid-morning Friday, Typhoon Mekkhala was moving northeast at 15 kilometers per hour off the coast of Kume Island in Okinawa. Meteorologists expected both systems to weaken as they moved inland and transitioned into extratropical cyclones, but the agency warned that this transition would not bring relief. Instead, the storms would continue to dump rain across vulnerable areas through Saturday. The Tokai region faced forecasts of up to 300 millimeters by noon Saturday, while the Kanto-Koshin region was expected to receive up to 150 millimeters. These were not marginal additions to already-saturated ground; they were significant rainfall events arriving on top of what had come before.
The meteorological agency urged the public to remain vigilant for landslides and flooding, acknowledging that the danger would persist even as the typhoons weakened. Okinawa Prefecture and eastern Japan faced the possibility of strong storms as Higos moved northward along the country's southern coast. The convergence of two weather systems, the saturation of the landscape, and the displacement of millions of people created a scenario in which the next 24 hours would determine whether the warnings had been heeded in time.
