Tokyo is an example of an urban heat island, and the phenomenon is especially serious in its special wards. According to the Tokyo Metropolitan Government, the annual mean temperature has increased by about 3°C over the past 100 years. Tokyo has been cited as a "convincing example of the relationship between urban growth and climate."
Demographics
As of October 2007, the official intercensal estimate showed 12.79 million people in Tokyo with 8.653 million living within Tokyo's 23 wards. During the daytime, the population swells by over 2.5 million as workers and students commute from adjacent areas. This effect is even more proclaimed in the three central wards of Chiyoda, Chūō, and Minato, whose collective population as of the 2005 National Census was 326,000 at night, but 2.4 million during the day.
