Toei Subway

The Toei Subway is a train system in Tokyo.

It has four different lines. Each line has its own color.

The Asakusa Line is rose. The Mita Line is blue.

The Shinjuku Line is black. The Oedo Line is magenta.

Many people use these trains every day. Millions of people ride them to move around.

These trains help people travel through the big city.

The Toei Subway is a big train system in Tokyo, Japan.

It helps millions of people travel every day. In 2023, about 2.85 million people used it daily. This is one of two main subway systems in the city. The other one is called Tokyo Metro.

The Toei Subway has four main lines.

Each line has its own color and name. The Asakusa Line is rose. The Mita Line is blue.

The Shinjuku Line is black. The Ōedo Line is magenta.

Building subways can be very expensive. For a long time, the system lost money. This was because building the tracks cost a lot. The Ōedo Line was very costly to build. However, the system made a profit in 2006.

Some trains use different track widths. We call these track widths gauges. The Toei Subway uses three different gauges. This helps trains move onto other private railway lines. These are called through services. They let passengers travel far without changing trains.

The Toei Subway is a major rapid transit system in Tokyo, Japan.

It helps millions of people travel around the city every day. In 2023, about 2.85 million people used these subway lines daily. This is one of two main subway systems in Tokyo. The other system is called the Tokyo Metro. These two networks are completely separate from each other. People with special prepaid passes can switch between them easily. However, regular ticket holders must buy a second ticket to change lines. There are two special stations where passengers can switch without a new ticket. These are Meguro and Kudanshita.

The system works using four different subway lines. Each line has its own special color and name. The Asakusa Line is rose and is the first to open.

The Mita Line is blue and was opened in 1968. The Shinjuku Line is black and started in 1978.

The Ōedo Line is magenta and is the longest line.

These lines use different track widths called gauges. This helps trains move onto other private railway lines. These trips are called through services. They let passengers travel far without changing trains.

Building a subway system is a very long and difficult job. In 1920, Tokyo City first proposed a plan for seven subway routes. However, a huge earthquake struck the city in 1923. This event changed how the city planned its transportation. The city also had a lot of debt from fixing the earthquake damage. Because of this, the city could not start building its own subway right away. At that time, private companies ran the only subway line. These companies later joined together to become the Tokyo Metro. The Toei Subway did not start building its own lines until 1958.

Many important dates helped shape the current Toei Subway. The first line began construction in 1958 between Kuramae and Magome. The Asakusa Line began running in 1960. Since then, the network has grown steadily over many years. The Mita Line opened in 1968 and the Shinjuku Line in 1978. The Ōedo Line became fully operational in 1991. Today, the entire system has 99 unique stations. Some counts say there are 106 total stations if you count every line. The total length of all the lines is 106 kilometers.

Managing a subway is a very big task for the government. Building the tunnels and tracks costs a huge amount of money. For most of its history, the Toei Subway lost money. The Ōedo Line was particularly expensive to build. Even so, the system reported its first net profit in 2006. That profit was 3.13 billion yen. This shows how much work goes into keeping a city moving. You can see how subways connect to the world around you. They link different parts of a giant city together through the ground.

The Toei Subway is a major rapid transit system located in Tokyo, Japan.

It is operated by the Tokyo Metropolitan Bureau of Transportation. This organization manages the system under a specific government ordinance for underground high-speed trains. The Toei Subway serves as one of the two primary subway operators in the city. The other major operator is the Tokyo Metro. While they both serve Tokyo, these two networks are completely separate systems. They function as two different layers of the city's massive transportation web.

Understanding how passengers move between these two networks is quite interesting. If a traveler uses a prepaid rail pass, they can switch between Toei and Tokyo Metro lines freely. However, passengers using regular tickets must purchase a second ticket to change networks. There are two specific exceptions to this rule where platforms are shared. On the Mita Line, the platforms between Meguro and Shirokane-Takanawa are shared with the Tokyo Metro Namboku Line. At Kudanshita station, the Shinjuku Line shares a platform with the Tokyo Metro Hanzomon Line. At these two locations, passengers can change lines without passing through a ticket gate.

The Toei Subway consists of four distinct lines, each with its own identity.

The Asakusa Line is identified by the color rose. It began operations in 1960 and connects Nishi-magome to Oshiage.

The Mita Line is blue and opened in 1968, running from Meguro to Nishi-takashimadaira.

The Shinjuku Line is black and has been running since 1978.

Finally, the Ōedo Line is magenta and is the longest line at 38 kilometers. This line became fully operational in 1991 and runs from Hikarigaoka to Tochōmae.

A unique technical feature of the Toei Subway is its use of different track gauges. A gauge is the distance between the two rails of a track. The Toei Subway is one of only two rapid transit systems in the world that uses three different track gauges. This is similar to the Barcelona Metro in Spain. The different gauges allow for through services, where Toei trains run onto tracks owned by private suburban railways. For example, the Asakusa Line connects to the Keisei Line. The Mita Line connects to the Meguro Line, which then links to the Tōkyū Shin-Yokohama Line and the Sōtetsu lines.

These connections allow passengers to travel long distances without needing to switch trains.

The history of the system began with early proposals in 1920. Tokyo City originally planned seven different subway routes. However, the Great Kantō Earthquake struck on September 1, 1923. This disaster caused massive damage to central Tokyo and changed how the city planned its infrastructure. Because of the high cost of earthquake reconstruction, the city faced large public debts. This made it difficult to get approval to start building a municipal subway. During this time, private companies operated the only subway, which eventually became the predecessor to the Tokyo Metro.

Construction of the Toei Subway finally began in 1958. This was driven by rapid economic growth and a growing population in the 1950s. As more people moved to Tokyo, road traffic increased and old tram systems became less effective due to congestion. The Tokyo Metropolitan Government obtained a license to build the first line between Kuramae and Magome. Since the opening of the Asakusa Line in 1960, the network has expanded steadily. This growth included the Mita Line in 1968, the Shinjuku Line in 1978, and the Ōedo Line in 1991.

Operating such a massive system involves significant financial challenges. Building underground tunnels and maintaining tracks involves very high construction expenses. Because of these costs, the Toei Subway ran at a financial loss for most of its history. The Ōedo Line was noted for being particularly expensive to construct. Despite these difficulties, the system achieved a major milestone in fiscal year 2006. It reported its first net profit of ¥3.13 billion, which is approximately $26.9 million. As of 2023, the Toei Subway carries an average of 2.85 million passengers every day.

Today, the network includes 99 unique stations across its four lines. If you count every station on every line, the total is 106 stations. The total length of the entire system is 106 kilometers. The system uses various types of rolling stock, which are the actual train vehicles. For example, the Asakusa Line uses 5500 and E5000 series trains. The Ōedo Line utilizes 12-000 and 12-600 series trains. These various lines and technologies work together to keep the massive city of Tokyo moving every single day.
