Japan began tackling its pollution problem back in the 1970s when particulate matter levels in the air.
Coal, wood and gas became the primary fuels that drove Japan to become one of the most technologically advanced countries by the late 20th century.
Since then, Japan has focused its efforts on tackling pollution in the following ways:
-A modal shift in national policy allowing local government leeway to tighten standards beyond national requirements
-Incentivizing business to adopt environmentally friendly technology and policy
-Modernizing older and inefficient power stations and factories
-Investing in pollution control technology
-Educating both the public and business communities
