This article examines the issue of pollution in Japan and its causes, effects, and solutions. Air pollution is caused by burning fossil fuels for energy production and transportation, while water pollution is caused by industrial waste, agricultural runoff, sewage discharge, and oil spills. This leads to serious health issues such as asthma, bronchitis, heart disease, cancer risk etc. The Japanese government has taken several measures to reduce air and water pollution including introducing tighter emissions standards for vehicles; implementing stricter regulations on industrial activities; providing incentives for businesses that adopt green technologies etc. Individuals can also help by carpooling instead of driving alone, using public transport instead of private vehicles, avoiding single-use plastics & switching over reusable items etc.
