World Car Free Day

What Is World Car Free Day?

Every year on September 22, the world observes "World Car Free Day," also known by the slogan "In Town, Without My Car!" The movement began in 1997 in La Rochelle, France, and has since spread to thousands of cities worldwide. The day encourages people in city centers to leave their cars at home and instead use public transportation, bicycles, or walking, offering a chance to reflect on issues like traffic congestion and air pollution while rediscovering a more human-friendly urban environment.

The History of "Reclaiming the City for Its People"

From a car-centered society to a people-centered one—Car Free Day has repeatedly prompted us to rethink how cities are designed.

• A movement born in Europe: In the 1990s, European cities faced serious issues such as historic buildings eroding from exhaust fumes and reduced quality of life due to traffic noise. In 1998, the French government threw its national support behind the movement, helping it spread across Europe as an effort to "reset" urban air quality.
• Adoption in Japan: Many Japanese cities, including Yokohama and Nagoya, take part in this event. Rather than a one-off event, it functions as a showcase for urban policy—testing improvements to public transit and pedestrian-only zones known as transit malls.

The Science of How Walking Activates the Brain's "Default Mode"

Stepping out of a car and starting to walk isn't just a change in how you get around—it's a scientifically backed way to optimize how your brain functions.

• Refreshing the prefrontal cortex: Driving keeps the brain in a heightened state of alertness, constantly scanning for hazards. Stepping away from the car and walking while taking in your surroundings shifts the brain into its "default mode network," a state neuroscience research links to creative thinking and reflection.
• Endorphin release and stress relief: The rhythmic movement of walking promotes the release of endorphins and serotonin, both associated with feelings of well-being. Breathing in clean air free of exhaust fumes while walking can lower cortisol (the stress hormone) and significantly improve mental health.

Interesting Facts About Car Free Day

• The "15-Minute City" concept: A major trend in current urban planning, the idea is to design cities so that everything you need—work, shopping, education, healthcare—is accessible within a 15-minute walk or bike ride. This is seen as a key solution for achieving carbon neutrality and maximizing residents' quality of life.
• The engineering of micromobility: Electric scooters and bike-sharing systems help bridge the "last mile" between public transit and final destinations, becoming an important piece of the puzzle in reducing excessive car use in cities.
• How noise affects cognitive function: Epidemiological studies have shown that reducing road noise and engine sounds is directly linked to improved learning ability in children and better sleep quality. A quiet city is, in many ways, infrastructure for nurturing intelligence.
• Easing the urban heat island effect: Eliminating exhaust heat from cars helps curb rising temperatures in city centers. Less reflected heat from asphalt and more greenery contributes to both physical and psychological coolness.
• The economic benefits of "detours": Driving tends to involve direct point-to-point travel, while walking opens up travel along lines and across areas. Walking increases the chances of stumbling upon hidden gems and local attractions, creating serendipitous boosts to local economies.

Ideas for Spending World Car Free Day

• To mark September 22, try traveling by public transportation or on foot instead of driving. Moving through the world at a slower pace can help you notice opportunities and beautiful scenery you might otherwise miss.
• Redefine what "travel" means to you. Instead of prioritizing speed, try enjoying the journey itself through mindful walking. Engaging your senses to notice the changing seasons gives your brain fresh stimulation and builds energy for the second half of the fiscal year.
• Do some bike maintenance. Taking care of the vehicle that carries you under your own power can boost your sense of self-efficacy and reinforce the feeling that you're in control of your own life.
• Check how walkable your neighborhood is. Notice where the benches are, where the shade is. Becoming aware of your living environment is a valuable form of self-care for maintaining well-being.
