Tokyo in trouble: Physical assets face double damage from climate change
Asia | Climate change
December 15, 2020 – If nothing’s done to adapt to and mitigate climate change, Tokyo would face severe costs if a one-in-100-year rainfall coincides with other major flooding events—raising the stakes from around $6 billion in damage to real estate and infrastructure today to about $13 billion in 2050.

Visual form
Four-metric grouped bar comparison chart.
Layout / body structure
The chart is a single row of four metric groups, each comparing Today with 2050. Read left to right from flooded area, to average flooded depth, to real-estate damage, and then to infrastructure damage.
What is being compared
The chart compares present-day versus 2050 flood effects in Tokyo under a climate-risk scenario. It covers flooded area, average flooded depth, real-estate damage and destruction, and infrastructure damage and destruction.
Measurement system
The first panel uses percent of modeled area, the second uses meters, and the last two use billions of dollars. Each pair uses dark bars for today and bright blue bars for 2050, with multiplier callouts added to the right of the last three metrics.
Visible structure inside the graphic
Four paired-bar groups line up across the page. The first panel shows flooded-area values of 64 and 81, the second shows depth rising from 0.3 to 0.5, the third shows real-estate damage rising from 5.9 to 13.1, and the fourth shows infrastructure damage rising from 0.4 to 1.1, with 1.7x, 2.2x, and 2.4x callouts emphasizing the scale change.
Main takeaway from the visual
Flooding in Tokyo is projected to become not only more widespread but also more damaging by 2050. The consistent taller blue 2050 bars across all four panels make the worsening physical and financial exposure visually explicit.
Key standout values or extremes
Flooded area rises from 64 percent to 81 percent, average flooded depth rises from 0.3 to 0.5 meters, real-estate damage rises from 5.9 to 13.1 billion dollars, and infrastructure damage rises from 0.4 to 1.1 billion dollars. The biggest relative multiplier shown is the 2.4x increase in infrastructure damage.
