On the morning of September 9th, 2026, Nagoya, Japan received 105 millimetres of rain in a single hour — a volume the city had never recorded in its entire meteorological history. The deluge overwhelmed drainage systems, halted public transportation, and fractured the intricate daily rhythms of millions of residents. Beyond the immediate disruption lies a deeper reckoning: what cities have built to withstand the past may no longer be sufficient for the future that climate change is delivering.
