On September 11, 2025, the Japanese capital of Tokyo experienced a sudden
0:21
and severe rainstorm that caused significant disruption to daily
0:25
life across the metropolitan area and surrounding regions.
0:57
The downpour, described by meteorologists as one of the
1:01
most intense localized rain events of the season,
1:04
struck during the afternoon hours, overwhelming drainage systems and triggering widespread alerts.
1:31
According to the Japan Meteorological Agency,
1:34
rainfall reached extraordinary levels, with certain parts of the Kanto region
1:39
recording 100 to 130 millimeters of precipitation within a single hour.
1:44
In central Tokyo, some districts reported as much as 12 centimeters of rain in just 60 minutes,
1:51
an intensity that exceeded warning thresholds and raised the risk of urban flash flooding.
2:34
Residents in low-lying areas and near rivers were placed on heightened alert,
2:38
while local governments issued emergency advisories
2:41
urging citizens to avoid unnecessary travel and to remain indoors until conditions improved.
3:17
The storm had an immediate impact on transportation and infrastructure.
3:22
At Haneda Airport, one of Tokyo’s busiest international gateways,
3:27
flight operations were temporarily suspended due to lightning strikes in the vicinity,
3:32
leaving passengers stranded and schedules disrupted.
3:35
The city’s extensive rail network also suffered interruptions:
3:40
bullet train services were suspended on certain routes,
3:43
while multiple commuter and subway lines experienced delays or cancellations,
3:48
stranding thousands of commuters across the capital.
4:17
The heavy rainfall was accompanied by hail in some districts, adding
4:21
to the challenges for pedestrians and motorists navigating flooded streets.
4:26
In many neighborhoods, roads were briefly transformed into streams
4:30
as drainage systems struggled to cope with the sudden deluge.
4:34
Social media posts shared widely showed cars partially submerged and residents
4:39
wading through ankle-deep water in areas such as Shinagawa, Meguro, and Ota wards.
4:55
The storm also caused power outages affecting more than seven thousand households.
5:01
The largest concentration of outages occurred in the southern wards of the city, though
5:06
blackouts were also reported in the greater Kanto region, including parts of Kawasaki and Yokohama.
5:12
Utility crews were quickly dispatched,
5:15
and power was restored to most households within several hours,
5:19
though temporary disruptions underscored the vulnerability
5:22
of the electrical grid to severe weather events.
5:44
Local governments in Tokyo’s Setagaya, Meguro, and Ota wards,
5:47
as well as neighboring municipalities, issued flood and landslide warnings.
5:53
Emergency response teams were placed on standby,
5:56
and evacuation advisories were prepared in case of further deterioration in weather conditions.
6:02
Fortunately, by the evening, rainfall intensity had subsided,
6:06
and no large-scale evacuations were required.
6:17
Meteorologists noted that this storm reflected a
6:20
broader trend of increasingly frequent and intense rainfall events in Japan,
6:24
linked to a combination of seasonal atmospheric
6:27
patterns and the long-term influence of climate change.
6:55
The government has emphasized the need for continued investment in flood-control
6:59
infrastructure, particularly in densely populated urban areas such as Tokyo,
7:05
where even short-lived downpours can lead to severe disruption.
7:37
Authorities urged residents to remain vigilant during the ongoing typhoon and rainy season,
7:42
stressing that similar extreme weather events are expected to
7:46
become increasingly common in the years ahead.
