The largest city in the world is a bustling metropolis with millions of inhabitants and a vibrant culture.

What is the current population of the largest city in the world?

The Largest City in the World

The largest city in the world by population is Tokyo, Japan. As of 2021, the estimated population of Tokyo is over 37 million people, making it one of the most populous cities on earth. The city itself spans over 2,000 square kilometers and is home to a diverse range of cultures and communities.

Population Growth

Tokyo’s population has been growing steadily for decades due to a combination of factors such as rapid urbanization, industrialization, and migration from other parts of Japan and abroad. The city’s economic opportunities have attracted people from all corners of the world, leading to a cosmopolitan mix of cultures that make Tokyo unique.


With such a large population living within its boundaries, Tokyo is also one of the densest cities on earth. The average population density in Tokyo is around 6,000 people per square kilometer. This high density presents significant challenges for policymakers and residents alike in terms of managing resources effectively and sustainably.

How did the largest city in the world come to be established?

A Brief History

Tokyo has a long and storied history dating back centuries. Originally known as Edo, it was established as Japan’s capital during the Edo period (1603-1868) under Tokugawa Ieyasu. During this time, Edo grew rapidly into a thriving center for commerce and culture.


Following Japan’s modernization in the late 19th century, Edo was renamed Tokyo (meaning “Eastern Capital”) and became even more prominent on both national and international stages. Throughout much of the 20th century, Tokyo continued to grow and develop into the sprawling metropolis it is today.

Post-World War II

After World War II, Tokyo was rebuilt as part of Japan’s post-war recovery efforts. The city experienced a period of rapid growth and development during the 1950s and 1960s, fueled by an influx of migrants from rural areas seeking work in the city’s booming industries. Today, Tokyo remains one of the most important economic centers in Asia and the world.

What are some of the challenges facing residents and policymakers in managing such a large and complex urban environment?


One of the biggest challenges facing residents and policymakers in Tokyo is managing the city’s infrastructure. With such a large population, there is a constant need for new housing, transportation, and other essential services. Ensuring that these services are provided efficiently and sustainably can be a significant challenge.


Tokyo’s transportation system is one of the most complex in the world, with multiple subway lines, train stations, and bus routes crisscrossing the city. Managing this system effectively requires careful planning and coordination between different agencies.

Environmental Sustainability

Another major challenge facing Tokyo is ensuring environmental sustainability. With such a large population living within its boundaries, there is a constant strain on natural resources like water and energy. Policymakers must find ways to reduce waste and emissions while also promoting sustainable practices like renewable energy and green spaces.

Waste Management

Managing waste is a significant challenge in Tokyo due to its large population and limited space for landfills. The city has implemented various measures to reduce waste production, including recycling programs and waste-to-energy facilities.

Social Issues

Finally, Tokyo faces several social issues that policymakers must address. One of the most pressing issues is income inequality, which can lead to social unrest and other problems if left unchecked.

Housing Affordability

Housing affordability is another issue facing many residents of Tokyo. With high demand for housing in the city center, prices have skyrocketed in recent years, making it difficult for lower-income residents to find affordable housing options.

In conclusion, determining the largest city in the world is a complex task that depends on various factors, including population density and geographical boundaries. However, it is clear that urbanization continues to rise globally, with megacities becoming more common than ever before.
