Japan, a nation long acquainted with the sea's fury, now faces a typhoon season that may test the outer limits of even its formidable preparedness. Forecasters predict up to 28 storms and 14 landfalls in 2026—figures that approach historical records and have already begun to materialize, as Typhoon Jangmi's landfall in Wakayama brought record rainfall, mass evacuations, and widespread disruption. The season raises a question that no engineering or early warning system can fully answer: how much can a society absorb before readiness becomes overwhelm? In this, Japan's struggle is not merely met
Japan braces for record typhoon season as forecasters predict up to 28 storms
Residents across multiple prefectures were forced to evacuate to higher ground due to Level 5 flood warnings and extensive landslide risks.
Japan's disaster systems are world-class, but they're being tested beyond design limits.

Why does Japan face such an outsized typhoon threat compared to other countries in the region?
Mimi
Geography is destiny here. Japan sits directly in the path of the northwestern Pacific typhoon belt, and its long coastline and mountainous terrain create conditions where storms intensify and stall. There's no escaping the storms—only preparing for them.
Mark
The forecast of 28 typhoons sounds extreme. How confident are meteorologists in that number?
Mimi
Weathernews bases these long-range forecasts on ocean temperature patterns, atmospheric conditions, and historical analogs. It's not a guess, but it's also not certainty. What matters is that even if the actual number lands lower, we're clearly in a high-impact season.
Mark
Jangmi already caused significant disruption. What happens if the next storm hits before cleanup is complete?
Mimi
That's the real nightmare scenario. Infrastructure gets fatigued. Soil saturated from one storm becomes unstable for the next. Evacuation fatigue sets in—people stop taking warnings seriously. The cumulative effect becomes worse than any single storm.
Mark
How prepared is Japan, really, for a season like this?
Mimi
Japan has the best disaster systems in the world. But there's a difference between being prepared and being prepared for the extreme end of the historical range. You can design for the 100-year storm, but when you're facing potentially 14 landfalls in one year, you're operating beyond the design envelope.
Mark
What's the economic cost beyond the immediate disruption we saw with Jangmi?
Mimi
It's not just cancelled flights and delayed trains. It's supply chains breaking, agricultural losses, insurance claims, reconstruction costs. And tourism—people simply won't come. A season like this could cost billions before it's over.
The Pulse
- Forecasters are warning of up to 28 typhoons affecting Japan in 2026—nearly double the typical season and edging toward the all-time record of 33 set in 1994.
- Typhoon Jangmi has already struck, dumping a record 52.6 centimeters of rain in 24 hours on Mie prefecture and triggering the highest flood alert level across multiple river systems.
- The storm's reach was immediate: 524 domestic flights cancelled, Shinkansen services halted, and residents across ten prefectures—including Tokyo—ordered to evacuate or brace for landslides.
- Japan's world-class disaster infrastructure is being stress-tested in real time, with evacuation systems, flood defenses, and transportation networks all strained simultaneously.
- The tourism sector, a key pillar of Japan's economy, faces mounting uncertainty as the storm season intensifies through what should be peak travel months.
- The country now confronts not the question of whether typhoons will arrive, but whether the cumulative weight of a near-record season can be absorbed without breaking the systems built to contain it.
Japan, a nation long acquainted with the sea's fury, now faces a typhoon season that may test the outer limits of even its formidable preparedness. Forecasters predict up to 28 storms and 14 landfalls in 2026—figures that approach historical records and have already begun to materialize, as Typhoon Jangmi's landfall in Wakayama brought record rainfall, mass evacuations, and widespread disruption. The season raises a question that no engineering or early warning system can fully answer: how much can a society absorb before readiness becomes overwhelm? In this, Japan's struggle is not merely meteorological but a mirror of the broader human reckoning with a climate that no longer behaves as it once did.
Japan is preparing for what may be its most punishing typhoon season in decades. Tokyo-based forecasting firm Weathernews has predicted up to 28 typhoons affecting the country in 2026, with as many as 14 expected to make landfall on the main islands—figures that far exceed the historical average and approach the outer edge of what modern records show is possible. In a typical year, only a handful of the northwestern Pacific's roughly 25 annual typhoon systems reach Japanese shores. The all-time record for formations stands at 33, set in 1994; the most landfalls ever recorded in a single season was 10, in 2004. This year threatens to rival or surpass both.
The season has already announced itself with force. Typhoon Jangmi came ashore in southern Wakayama prefecture in the early hours of June 3, and its aftermath was still being cleared days later. The Japan Meteorological Agency issued its highest alert—Level Five—for flooding along multiple Wakayama rivers, ordering immediate evacuations. Level Four warnings, signaling serious flood and landslide risk, spread across ten prefectures including Tokyo and Kanagawa. In the Mie prefecture town of Owase, 52.6 centimeters of rain fell in a single day—the highest monthly rainfall ever recorded there. Airlines cancelled 524 domestic flights; the Shinkansen and regional rail networks ground to a halt or fell into severe delay.
What gives the forecast its particular weight is what it implies for the months ahead. Japan's disaster management systems are among the most sophisticated in the world, shaped by generations of typhoon experience. But a season approaching historical extremes will push those systems—evacuation protocols, flood defenses, transportation networks—to their limits all at once. The tourism sector, already a vital economic engine, faces the prospect of disruption during peak travel months. The deeper challenge Japan now faces is not preparation for any single storm, but the question of how many storms a society can absorb in sequence before readiness itself begins to fray.
Japan is bracing for what could be the most severe typhoon season in decades. Weathernews, a Tokyo-based forecasting firm, has predicted that as many as 28 typhoons will affect the country this year, with roughly half of them—up to 14—expected to make landfall on Japan's main islands. These numbers sit well above historical norms and approach the outer limits of what the country has experienced in the modern record.
In an average year, the northwestern Pacific generates about 25 typhoon systems, but only a handful typically reach Japan's shores. The country has never seen more than 33 typhoons form in a single year, a record set in 1994. The most landfalls ever recorded in one season was 10, which occurred in 2004. If Weathernews's forecast holds, this year could rival or exceed those benchmarks.
The season is already making its presence felt. Typhoon Jangmi made landfall in southern Wakayama prefecture in the early morning hours of June 3, and cleanup efforts were still underway across central Japan days later. The storm prompted the Japan Meteorological Agency to issue its highest alert level—Level Five—for flooding along multiple rivers in Wakayama, ordering residents to evacuate to higher ground immediately. Level Four warnings, indicating extensive flooding and landslide danger, were issued across a wider swath of the country, including Tokyo, Kanagawa prefecture, and seven other prefectures in eastern Japan.
The disruption was immediate and widespread. Airlines cancelled 524 domestic flights in response to the storm. The Shinkansen bullet train network, along with regular rail services and metro systems, either halted operations or experienced severe delays that rippled through the transportation system. In the town of Owase, located in Mie prefecture, the storm dumped 52.6 centimeters of rain in a single 24-hour period—the highest monthly rainfall recorded there to date.
What makes this forecast particularly sobering is the timing. Japan's infrastructure, while among the world's most advanced, is already being tested by the increasing intensity and frequency of extreme weather events. The country's disaster management systems, evacuation protocols, and physical defenses have been refined through decades of typhoon seasons, but a year approaching historical extremes will push those systems to their limits. Tourism, a vital economic sector, faces potential disruption as well, with travelers likely to cancel or postpone trips during peak storm months.
As the season deepens, the question facing Japan is not whether typhoons will arrive, but how many the country can absorb without overwhelming its preparedness infrastructure. The forecast from Weathernews serves as a stark reminder that even a nation with sophisticated early warning systems and well-practiced evacuation procedures cannot simply engineer its way around the raw power of nature at scale.
