In the 1960s, Japan faced severe air and water pollution in industrial areas, with reports of health damage among citizens in Yokkaichi and Kawasaki. Major pollution issues such as Minamata disease and Itai-itai disease caused by industrial waste led to the establishment of the Environment Agency.
2. ASEAN's Environmental Standards and Economic Development
ASEAN countries are working to harmonize international and regional standards, focusing on balancing economic development with ecosystem protection. The challenge lies in maintaining both growth and environmental conservation.
3. Mercury Pollution and the Expansion of Minamata Disease
Minamata disease, which began in the late 1950s, was caused by mercury pollution in Minamata Bay, Kumamoto Prefecture. Despite the Ministry of Health's recognition of the pollution, inadequate measures led to worsening conditions. Similar pollution in Niigata Prefecture resulted in a second Minamata disease.
4. Soil Pollution and Environmental Destruction from Pesticides
From the 1960s to the 1970s, the widespread use of pesticides led to severe soil pollution in rural areas. Organic mercury and organophosphorus pesticides were particularly problematic, raising health concerns and leading to calls for stricter pesticide regulations.
5. Environmental Pollution During Japan's High Economic Growth Period
Japan's industrialization during its period of high economic growth resulted in widespread environmental pollution. The shift from coal to oil and the construction of industrial complexes led to significant air and water pollution, exacerbating pollution issues in urban areas.
6. Photochemical Smog and Urban Environment
In the 1970s, a photochemical smog incident in Suginami, Tokyo, caused many students to collapse, highlighting the severity of urban air pollution. This incident intensified public criticism of the government and led to stricter air pollution controls.
7. Marine Pollution from Industrial Wastewater
In 1958, industrial wastewater from Honshu Paper's Edogawa plant polluted fishing grounds in Urayasu, leading to a violent protest by fishermen. This event prompted the enactment of the Water Pollution Control Law and the Factory Wastewater Regulation Law, managed by the Economic Planning Agency, reflecting heightened expectations for environmental protection among local residents.
8. Development of Japan's Environmental Administration
Before the establishment of the Environment Agency, pollution control was led by the Ministry of Health and local governments, but limitations in these efforts were evident. The Basic Law for Environmental Pollution Control was enacted in 1967, calling for centralized environmental administration.
9. Land Subsidence and Groundwater Pumping Regulations
In the 1960s, land subsidence in Nagoya and Osaka, caused by excessive groundwater pumping, had a significant impact on urban environments. Regulations on groundwater extraction were implemented, but their effectiveness was limited.
10. Enactment and Impact of the Basic Law for Environmental Pollution Control
The Basic Law for Environmental Pollution Control, enacted in 1970, clarified corporate responsibility for pollution prevention. However, industry resistance to balancing economic development with environmental protection presented challenges in advancing environmental conservation.
