How is Japan affected by climate change? The issue of climate change is a worldwide concern, presenting substantial risks to the environment, economies, and societies.

Japan is renowned for its cutting-edge technological progress, diverse cultural legacy, and breathtaking natural wonders.

But, like every other country in the world, Japan is certainly not immune to the far-reaching effects of climate change.

But, how does Japan’s climate change truly affect it? Let’s find out now!

Climate change affects Japan through severe weather, rising temperatures, and sea level rise, which impact Japan’s infrastructure, agriculture, and coastal populations. 

How Is Japan Affected by Climate Change?

Being a country located on an island in a region known for its unpredictable weather patterns and susceptibility to increasing sea levels, Japan encounters a variety of climate-related difficulties.

Here is a bit about some possible consequences of climate change in Japan: 

Rising Temperatures and Heatwaves

Throughout the previous century, Japan has experienced a consistent rise in temperatures, a trend that is expected to continue.

Hottest monthAug, 28C
Windiest monthApr, 17km/h
Wettest monthJun, 57.5 mm

The Problems with Heatwaves

Climate change has led to a significant increase in scorching heat waves during the summer months.

The severe heat events pose significant concerns for the well-being of the general population, particularly older people and other susceptible individuals.

Moreover, Japan’s agricultural industry encounters notable obstacles, as increasing temperatures strain crops and livestock, putting food production and security at risk.

Fact: Immediate steps have to be taken regarding climate change to protect both the well-being of people and the long-term viability of the nation's food supply. 

Changing Precipitation Patterns

The precipitation patterns in Japan have undergone significant changes due to climate change, resulting in notable repercussions.

The annual precipitation is around 365.5 mm/year, but there are notable shifts due to climate change.

Certain areas are currently experiencing increased precipitation, leading to a rise in the occurrence of more frequent and intense floods and landslides

The Problems Caused by Precipitation

The severe weather occurrences cause significant damage to:

  • Vital infrastructure
  • Hinder transportation systems
  • Jeopardize the safety of individuals and assets
the problems caused by precipitation

On the other hand, different regions of the nation experience extended periods of dry spells, putting pressure on:

  • Water supplies
  • Farming productivity
  • The harmony of ecosystems
Fact: The convergence of extended periods without rain and growing water needs may result in a shortage of water in cities and farming areas. 

Typhoons and Extreme Weather Events

Due to its geographic position, Japan is prone to typhoons, which are tropical cyclones that originate in the western Pacific Ocean.

Anticipated changes in climate are expected to affect the occurrence and strength of these storms.

Although the total quantity of typhoons may not experience a substantial increase, there are indications pointing towards a possible escalation in their strength.

Typhoons of immense strength bring about catastrophic outcomes.

It happens due to:

  • Destructive gusts
  • Heavy precipitation
  • Surges of stormy waters

Consequently, societies and sectors encounter extensive harm and disturbances, leading to consequences for infrastructure, farming, and coastal areas.

Fact: Preparedness and resilience measures are crucial in order to reduce the impact of heightened typhoons in Japan, protecting lives and minimizing financial damages. 

Sea-Level Rise and Coastal Erosion

Being a country made up of multiple islands, Japan is particularly susceptible to the impacts of rising sea levels caused by global warming.

It is due to two main reasons:

  • The melting of polar ice
  • The expansion of seawater

The growing danger presents notable hazards to coastal areas at lower elevations, raising the chances of:

  • Severe floods
  • Infiltration of saltwater
  • Erosion along the coast 

Areas at Higher Risks

areas at higher risks

The challenges faced by Japan’s coastal communities, especially in highly populated cities like Tokyo, Osaka, and Yokohama, are of utmost importance.

Infrastructure, housing, and economic activities in these regions face significant risks, requiring urgent adaptation strategies and resilient measures. 

Impact on Agriculture

Japan’s economy heavily relies on agriculture, making it highly vulnerable to the effects of climate change.

Variations in temperature and rainfall patterns have a direct impact on crop yields and the conditions for growth, which could potentially put food production at risk.

In addition, the alteration of rainfall patterns and the availability of water present considerable challenges for irrigation and efficient water management in agriculture.

In the case of extended periods of dry weather, there is a possibility of experiencing a shortage of water.

In contrast, an abundance of rainfall can cause erosion of the soil and excessive water accumulation.  

Fact: Increasing temperatures can also contribute to the spread of pests and diseases, posing extra difficulties for farmers. 

Threats to Biodiversity and Ecosystems

Japan boasts a wide array of ecosystems and unparalleled biodiversity.

Climate change, specifically the increase in temperatures, changes in precipitation patterns, and the occurrence of severe weather events, presents substantial risks to these ecosystems.

Certain plant and animal species might encounter difficulties adjusting to evolving circumstances, resulting in alterations in species distributions and potential threats of extinction.

Moreover, the increasing levels of the sea and the erosion of coastlines have the potential to affect precious coastal ecosystems, such as wetlands and mangrove forests

Impact on Fisheries

impact on fisheries

The fishing industry in Japan is renowned for its size and significant contribution to the country’s economy and food security.

However, the alteration in climate patterns has the potential to disturb the delicate balance of marine ecosystems and the geographical spread of various fish species.

This impacts the abundance of fish and the productivity of fishing activities.

The absorption of excessive carbon dioxide from the atmosphere leads to ocean acidification.

This in turn presents an additional danger to marine life, especially shell-forming creatures such as oysters and scallops. 

Fact: Climate change coupled with overfishing are the reasons why you see fewer fish available to catch in Japan.

Urban Challenges

urban challenges

The effects of climate change extend beyond rural regions and encompass urban areas in Japan as well.

Urban areas experience the heat island phenomenon, wherein cities become notably hotter than the surrounding rural regions as a result of human activities and the prevalence of heat-absorbing surfaces.

Urban heat islands have the potential to worsen heat waves and affect the well-being of the public, energy usage, and the performance of infrastructure.   

Economic Consequences

Japan is facing economic consequences as a result of various climate-related challenges.

The nation might encounter escalated expenses for managing and recuperating from disasters, along with the requirement for infrastructure that can withstand climate-related challenges.

Reduced productivity and damage from extreme weather events could potentially lead to losses in the agricultural and fisheries sectors.

Moreover, the tourism sector is a crucial component of Japan’s economy but it might face the impact of climate-induced alterations in natural landmarks. 

Fact: Glacial retreat in the mountainous regions is the outcome of climate change and jeopardizing freshwater resources in Japan.

Japan’s Climate Change Mitigation Efforts

3. Additional Efforts to Adapt to Climate Change

In terms of adapting to climate change, Japan has taken steps to improve its ability to withstand the effects.

For instance, the country is actively seeking out inventive measures to tackle the pressing issue of increasing sea levels.

This includes investigating unique approaches such as:

  • Implementing coastal safeguards
  • Promoting environmentally friendly urban development
  • Establishing eco-friendly infrastructure

The government also promotes the advancement of climate-resilient infrastructure and urban planning to alleviate the consequences of heat waves and extreme weather occurrences.
