Japan's Pollution Problem: A Comprehensive Overview

Japan is one of the most air-polluted countries in the world, with over 44,000 deaths annually attributed to air pollution. The country's rapid industrialization, economic growth, and increasing population have contributed to air, land, and marine pollution. Volcanic eruptions, typhoons, earthquakes, and tsunamis also cause waste pollution. Japan's fishing industry is suffering from the consequences of climate change, with coral reefs and fish nurseries being damaged, driving down fish stock rates. Japan has introduced environmental protection laws and regulations to combat pollution, but its efforts have been criticized as insufficient, particularly in abandoning fossil fuels.

Japan's air pollution problem

Japan is one of the most air-polluted countries in the world. Air pollution is the biggest environmental issue in the country, causing over 40,000 deaths annually. The leading causes of air pollution in Japan are vehicle emissions and industrial production, both of which are a result of fossil fuel combustion.

The history of pollution in Japan can be traced back to the Meiji Period, with the mineral pollution case of the Ashio Copper Mine. Since World War II, Japan has experienced rapid industrialization, which has resulted in a massive increase in industrial manufacturing and pollution. This has led to terrible pollution-related diseases, including Minamata disease and Yokkaichi asthma.

In response to rising pollution levels and public pressure, the Japanese government has implemented various anti-pollution measures and regulations. The National Diet session of 1970, also known as "the Pollution Diet," passed fourteen anti-pollution laws, including a Water Pollution Act and nationwide regulations of toxic discharges. The government has also promoted the 3R initiative, which encourages the reduction, reuse, and recycling of waste. However, Japan's waste recycling rate has remained low, at around 20% over the past decade.

While Japan has made efforts to improve its environmental policies and regulations, it is still lagging in sustainability and environmental protection. As a member of the Paris Agreement, Japan needs to boost its sustainability efforts and strengthen its environmental policies to address its air pollution problem effectively.

Industrialisation and environmental disasters

Japan's history of pollution can be traced back to the Meiji Period, when the country prioritized industrial growth, which led to severe environmental challenges. The pursuit of rapid economic growth and industrialization came at the cost of environmental damage, with the government refusing to acknowledge or address major environmental disasters during the 1950s and 1960s. This period saw Japan's first encounter with industrial pollution, with the Ashio Copper Mine causing mineral pollution and health issues such as copper poisoning among nearby residents.

The postwar period, from 1945 to 1970, was marked by rapid economic growth and unbridled pollution, with industrialization causing heavy air and water pollution, and soil contamination. The government's single-minded focus on economic reconstruction led to a disregard for environmental protection, resulting in public health issues. During this time, Japan experienced several major environmental disasters, including mercury poisoning in Minamata and Niigata, and cadmium poisoning in Toyama. These incidents sparked public outrage and increased awareness of the need to protect the environment.

In response to the growing environmental concerns, Japan entered a new phase of environmental protection from 1970 to 1989. The government enacted several critical environmental laws, such as the Water Pollution Control Law in 1970, which prohibited the discharge of wastewater that did not meet quality standards. The establishment of the Environmental Agency in 1971 demonstrated Japan's commitment to addressing pollution. Additionally, the Basic Law for Environmental Pollution Control was enacted to promote comprehensive and systematic pollution control measures.

Despite these efforts, Japan continues to face significant environmental challenges. Air pollution remains the country's biggest environmental issue, causing over 40,000 deaths annually. The leading causes of air pollution are vehicle emissions and industrial production, resulting from fossil fuel combustion. Japan's waste management practices, including a heavy reliance on waste incineration, further contribute to air pollution and greenhouse gas emissions. While Japan has set ambitious targets for reducing carbon emissions and has made strides in energy efficiency, it still faces criticism for its slow abandonment of fossil fuels and lack of progress in waste recycling.

Natural disasters and waste pollution

Japan is highly vulnerable to natural disasters due to its climate, topography, and location in the Ring of Fire. The country experiences frequent earthquakes, typhoons, floods, tsunamis, cyclones, and volcanic eruptions, which contribute to waste pollution on land and in the ocean.

Japan's rugged topography, with numerous faults and steep inclines, exacerbates the impact of earthquakes. Located in the Pacific earthquake belt, Japan is frequently struck by earthquakes, with the 1923 Great Kanto earthquake being the deadliest recorded natural disaster, claiming approximately 105,000 lives. The country has also experienced several major mudslide events triggered by earthquakes and heavy rainfall, such as the Otaki earthquake in 1984 and Tropical Storm Talas in 2011, resulting in significant casualties.

Typhoons are another common occurrence in Japan, bringing strong winds, heavy rainfall, and storm surges, which cause river flooding and flash floods. The Ise Bay Typhoon in 1959 was one of the deadliest typhoons, resulting in over 5,000 deaths. More recently, in 2019, Typhoon Hagibis caused severe flooding and landslides, leading to significant damage and loss of life.

Tsunamis pose a significant threat to Japan's coastline, with the 2011 tsunami resulting in devastating consequences, including the Fukushima Daiichi nuclear disaster. In response, the government initiated the construction of sea walls along vulnerable coastal areas to protect against future tsunamis.

Volcanic eruptions also contribute to waste pollution, emitting large quantities of pollutants into the atmosphere. Japan is located in the circum-Pacific zone, which contains almost all of the world's volcanoes, with 83 active volcanoes within its territory.

To address these challenges, Japan has implemented various measures for disaster prevention and mitigation. Since the 1960s, the country has actively strengthened physical and institutional safeguards, leading to a significant decline in disaster-related deaths. The government has also enacted laws, such as the Disaster Countermeasures Basic Act and the Water Pollution Control Law, to manage flood risks and reduce water pollution.

However, waste management remains a persistent issue in Japan due to limited landfill space. The country relies heavily on waste incineration, which contributes to greenhouse gas emissions and negatively impacts local communities' health. Japan has also been criticized for its slow transition away from fossil fuels, which remain the largest source of electricity generation, contributing to air pollution and carbon dioxide emissions.

Governmental anti-pollution measures

Japan has been facing environmental issues due to rapid industrial development, economic growth, and the increase in its population. Air pollution is the biggest environmental concern in Japan, causing over 40,000 deaths annually. The leading causes of air pollution are vehicle emissions and industrial production, both resulting from fossil fuel combustion.

The Japanese government has implemented several measures to combat pollution, including:

• The Basic Law for Environmental Pollution Control: This was enacted in the 42nd year of the Showa Period to promote comprehensive and systematic pollution control measures. It aimed to address the issues caused by rapid industrialisation and heavy manufacturing, which had led to a concentration of pollutant sources in waterfront areas.
• Water Pollution Control Law: Passed in 1970, this law prohibits the discharge of wastewater that does not meet effluent water quality standards. It aims to prevent the pollution of water in public water areas by regulating the discharge from factories and businesses.
• Air Pollution Control Act: This act regulates smoke, soot, and dust from factories and businesses. It also implements countermeasures for hazardous air pollutants and stipulates allowable limits for automobile exhaust gases.
• Automobile NOx/PM Act: This special measures law aims to reduce nitrogen oxides and particles from cars in specific regions.
• 3R Initiative: The government promotes this initiative to encourage businesses and citizens to reduce, reuse, and recycle waste.
• Basic Energy Plan: The cabinet approved this plan, which aims to realise the Net Zero Energy House (ZEH) concept in newly constructed houses by 2020 through efficient heating and cooling.
• Food Recycling Law: Announced in 2019, this legislation mandates a national directive and local municipal action to halve business-related food loss and waste by 2030.
• Transport Sector Initiatives: Japan has continuously tightened emission standards for vehicles, focusing on high-emitting heavy-duty trucks and buses. All new diesel vehicles are now equipped with diesel particulate filters.
• International Cooperation: Japan has partnered with other countries, such as Vietnam and Thailand, to install fluorocarbon destruction facilities and promote fluorocarbon lifecycle management.
• Investment in Environmental Preservation: The Japan Bank for International Cooperation launched the Global Facility to promote Quality Infrastructure Investment for Environmental Preservation and Sustainable Growth (QI-ESG) to increase financing for environmentally friendly infrastructure development.

While Japan has taken some steps to address pollution, it faces challenges in fully transitioning from fossil fuels and improving its waste recycling rates. As a member of the Paris Agreement, Japan is expected to boost its sustainability efforts and enhance its environmental policies.

International criticism and cooperation

Japan has been criticised for its poor environmental track record, particularly concerning air pollution. As one of the world's leading developed countries, Japan is expected to be a leader in environmental protection, pollution control, sustainability and the energy transition. However, Japan has been slow to act on sustainability.

Japan's history of pollution can be traced back to the Meiji Period, with the Ashio Copper Mine case. After World War II, Japan's industrialisation led to a massive increase in pollutants, causing diseases such as Minamata disease and Yokkaichi asthma. Japan has since taken steps to address pollution, including enacting the Basic Law for Environmental Pollution Control in 1967, establishing the Environmental Agency in 1970, and introducing the Basic Environmental Law in 1993. However, these measures did not solve the problem, and Japan continues to struggle with waste management and air pollution.

International criticism of Japan's environmental efforts has been ongoing. Climate Action Tracker ranks Japan's climate mitigation efforts as "insufficient". Japan's fishing industry has also been criticised for overfishing, with seafood production falling by 66% between 1985 and 2017.

To address these issues, Japan has engaged in international cooperation and agreements. As a member of the Paris Agreement, Japan has committed to boosting sustainability and improving environmental policies. Japan has also partnered with the US EPA to curb vehicle emissions, improve air quality, reduce plastic waste, and manage chemical pollution. Japan is further cooperating with the US on the Global Methane Pledge to reduce methane emissions in the waste sector.

Additionally, Japan has launched initiatives such as the Zero Emissions Tokyo Strategy, aiming to achieve net-zero carbon emissions and reduce short-lived climate pollutants. Japan has also established laws to regulate fluorocarbons and set reduction targets for methane and HFCs. Japan's International Cooperation Agency (JICA) works with other countries and organisations to promote environmentally friendly infrastructure development and achieve Sustainable Development Goals.

Through these international partnerships and agreements, Japan is taking steps to improve its environmental performance and address the criticism levelled at its previous lack of action.
