Like many cities in the world, Tokyo has been suffering from heat Island effect, but researchers say it has gotten worse in recent years. Increasing high-rises along the bay area is preventing wind from the coast to flow into the metropolis. Preventing efficient heat transfer in the lower atmosphere, trapping the heat inside.
Authorities say over 4500 people were taken to hospitals in Tokyo last year for heatstroke 10 times the number in year 2000. This month already over 230 people suffered from hear exhaustion. The metropolitan government is now promoting green buildings projects and laying water retentive tarmacs. But experts say bigger scale measures are needed to have significant impact.
