Central Tokyo has seen a record 35 straight days of rain.

The prolonged wet spell, driven by El Niño and stalled weather fronts, breaks the previous record set in 2019. This unprecedented rainfall is straining urban drainage systems and causing significant disruptions to daily life.

Residents have faced flooding, delays, and cancellations as the relentless rain continues unabated.

The long-term vulnerability of Tokyo's infrastructure to extreme precipitation events is highlighted by this extended rainy period. Continued climate change could exacerbate such conditions, leading to more frequent and severe pluvial flooding.

What is the long-term climate outlook for this region?

The increasing frequency of prolonged rain events in Tokyo suggests a need for enhanced drainage infrastructure. Climate models predict that El Niño could become more intense, leading to heavier rainfall and greater flood risks.

Outlook remains negative with increased risk of flooding.
