What You'll Learn
Japanese cars are 36% more fuel-efficient than in 2009
Japanese cars have become significantly more fuel-efficient over the past decade, achieving a 36% increase in fuel efficiency from 2009 to 2018. This improvement is the result of a combination of factors, including technological advancements, government regulations, and a shift towards hybrid and electric vehicles.
Japan is renowned for its innovative approach to technology, and this extends to its automotive industry. Japanese car manufacturers have consistently strived to enhance the fuel efficiency of their vehicles, resulting in notable improvements over time. Between 2005 and 2019, the average fuel consumption of new light-duty vehicles (LDVs) in Japan decreased by 2.4% annually, outpacing other major LDV markets.
Government regulations have played a pivotal role in this transformation. In 2019, the Japanese government mandated a target for car manufacturers to increase fuel efficiency by more than 30% by 2030. This builds upon previous initiatives, such as the Top Runner Program, which sets standards for corporate average fuel economy. The program's target for the 2015 fiscal year was a 23.5% improvement in fuel economy from 2004, demonstrating the government's commitment to reducing emissions.
Japan has the highest sales share of hybrid powertrains among major LDV markets, with 18% of sales in 2019 attributed to hybrid vehicles. Iconic cars like the Toyota Prius, introduced in 1997, have paved the way for hybrid technology, influencing the wider automotive industry. Additionally, Japan has a unique category of vehicles known as Kei cars, which are designed to be as small and lightweight as possible to maximize fuel efficiency within the constraints of a gas-powered engine.
The shift towards hybrid and electric vehicles is a key contributor to the overall increase in fuel efficiency. While electric and plug-in vehicles currently represent a small portion of LDV sales, Japan has set ambitious goals for the coming years. The country aims to increase the percentage of electric and plug-in hybrid vehicles by 20% to 30% in the next decade, aligning with its zero-emissions targets.
In summary, Japanese cars have achieved impressive gains in fuel efficiency, surpassing the targets set by the government. This success is attributable to a combination of factors, including Japan's technological prowess, stringent government regulations, and the growing popularity of hybrid and electric vehicles. As Japan continues to prioritize bringing fuel-efficient vehicles to the global market, we can expect further advancements and innovations in this domain.

The country's zero-emissions targets
Japan has set ambitious targets to achieve a carbon-neutral society by 2050, including the elimination of gasoline-powered vehicles by the mid-2030s. This plan, known as the "green growth strategy," aims to generate nearly $2 trillion annually in green growth by 2050 and achieve net-zero carbon emissions. The strategy identifies 14 industries, including offshore wind and fuel ammonia, with a focus on increasing the use of renewable energy sources.
However, Japan's current policies and actions are not aligned with the Paris Agreement and are projected to result in emission levels of only 31-37% below 2013 levels by 2030, falling short of their NDC target of a 46% reduction. Japan's latest Green Transformation strategy, the GX Basic Policy, has been criticized for lacking concrete emissions reduction targets and prioritizing economic growth and energy security over ambitious decarbonization efforts.
To improve its climate targets and actions, Japan should consider committing to a full coal phase-out, setting more aggressive electricity mix targets for 2035, prioritizing the expansion of renewable energy sources, and strengthening its EV target to phase out all fossil-fuel passenger cars from new sales by 2035. Additionally, Japan has pushed back against a G7 target for all new car and van sales to be zero-emission vehicles by 2035, instead advocating for a more flexible approach that includes hybrid vehicles.
While Japan has the highest sales share of hybrid vehicles among major LDV markets, the pace of fuel economy improvements has slowed in recent years, and the country continues to face scrutiny from green investors for its slow embrace of zero-emission vehicles. Nevertheless, Japan remains committed to achieving its long-term goal of carbon neutrality by 2050 and is taking steps to incentivize companies to invest in future technology and support the transition to a green economy.

The rise of hybrid and electric cars
Japan has long been a leader in automotive innovation and is one of the world's top manufacturers of automobiles. The country has been making a concerted effort to boost the fuel efficiency of its cars. According to statistics, Japan's cars became 36% more fuel-efficient from 2009 to 2018, with the average fuel efficiency of a new gasoline-powered car rising from 53.1 MPG to 39 MPG during that period.
One of the main reasons for the increase in fuel efficiency from Japan's car industry is the steady supply of hybrid and electric cars entering the market. Japan has the highest sales share of hybrid powertrains among all major LDV markets, with an 18% share in 2019. The Toyota Prius, for example, has been a pioneer in the hybrid market since 1997 in Japan and 2000 in the US. Other fuel-efficient cars from Japan include the Mazda CX-3, Honda Fit, Honda CR-V, and Toyota Corolla Hybrid.
While Japan has been slow to adopt fully electric vehicles, it has dominated the global market for hybrid vehicles, hoping to leverage its investment in this technology. The country has set a goal of increasing the percentage of electric and plug-in hybrid vehicles by 20-30% by 2030. To encourage the transition, Japan is investing in EV R&D, focusing on improving battery and charging technology. The government is also providing subsidies and tax incentives for manufacturers and buyers to boost EV and hybrid adoption.
Japan has also set a deadline of 2035 to become fully electric, banning the sale of new gas-powered cars. This shift towards an electric future is evident in the growing interest in electric fleets, with companies like DHL Express deploying electric trucks in Japan in 2023. However, challenges remain, including limited resources, supply chain disruptions, and inadequate charging infrastructure.
As the world moves towards an electric future, Japan, with its innovative spirit and automotive expertise, is well-positioned to continue improving the fuel efficiency of its vehicles and increasing the adoption of hybrid and electric cars.

Kei cars are small, lightweight, and fuel-efficient
Japanese cars are known for their fuel efficiency, and the country is one of the leading manufacturers of automobiles in the world. The average fuel efficiency of a new gasoline-powered car rose from 53.1 MPG to 39 MPG between 2009 and 2018, a 36% increase. This can be attributed to Japan's innovative approach to technology and its zero-emissions targets.
Kei cars are a prime example of Japan's commitment to fuel efficiency. Kei cars are designed to be as small and lightweight as possible to maximise their fuel efficiency. Their compact size makes them ideal for navigating busy cities and tight spaces, and their low power and high driving ranges make them a popular choice for city dwellers. Some of the most famous Kei cars include the Honda Beat, Suzuki Wagon R, Daihatsu Copen, and Suzuki Alto.
Kei trucks, in particular, have impressive fuel economy, with many models achieving 30 to 40 miles per gallon of gas, and sometimes even 35 to 45 mpg in mixed driving conditions. Their lightweight materials and streamlined shapes contribute to their frugal fuel usage, and their compact size and efficient engines are crafted to fit within the kei car category regulations.
The Subaru Sambar, the first kei truck, was introduced in 1959 and could reach speeds of up to 75 miles per hour. Today, kei trucks continue to be a versatile and cost-effective choice for both personal and commercial use, offering high mileage and minimal operational costs.
However, the future of Kei cars is uncertain, as Japan has set a deadline of 2035 to become fully electric. With the increasing demand for electric vehicles, the popularity of Kei cars, which are primarily gas-powered, may decline. Nonetheless, Kei cars have played a significant role in Japan's automotive industry and have contributed to the country's reputation for producing fuel-efficient vehicles.
