Air pollution in Tokyo

Japan experienced severe environmental issues during the period of 1955 to 1970. In this period, air pollution was significant in industrial complex areas. The Yokkaichi industrial area, in which many petrochemical factories were located, was notorious for its air pollution. Air in the Keihin industrial area, including seaside areas of Kawasaki and Yokohama, was also contaminated by air pollutants originating from petroleum burning. Residential areas in Tokyo also experienced severe air pollution due to heavy traffic loads. A number of people were damaged by the air pollution, and people were even killed in the worst case.

During the period, a relationship between a cause and its result was simple. Production activities required oil burning, and pollution control technique was not matured. Thus, air pollution was inevitable issues at that time. A relationship between light and shadow were really understandable. You would have good reasons to say that economic activities were enemy to your environment at a loud voice.

I am currently living in a residential area in Tokyo, but am able to breathe air prevailing in Tokyo. I believe that acute toxicities arising from air pollution is not almost at a concerned level in Tokyo. This is thanks to recent emergences of environment-friendly vehicles and severe technical and regulatory pollution prevention measures taken in Japan for the past several decades. Although air pollution levels along main road side areas in Tokyo should be still taken cared about, I can find a residential place in the metropolitan Tokyo where I have not to take care about air pollution.


However, I cannot say anything about newly appearing air pollutants: radioactive substances coming from the Fukushima Daiichi nuclear power plant. I am not totally sure whether the radioactive substances will cause negative impacts on your health in the future.
