Tokyo subway sarin attack

Long ago, a group did something very bad.

This group was called Aum Shinrikyo. They wanted to take power in Japan.

In 1995, they hurt people on trains. This happened in the city of Tokyo. They used a bad gas on the trains.

Many people were hurt that day. It was a very sad time for the city. Many people felt scared on the subway.

Soon, the police came to help. They caught the leaders of the group. They also arrested many members.

The leaders were sent to prison. This helped make the city safe again.

Now, people remember this day.

In 1995, a group in Japan did something very bad.

The group was called Aum Shinrikyo. They were led by a man named Shoko Asahara. This group believed in a scary end to the world. They wanted to take power in Japan.

On March 20, 1995, they attacked the Tokyo subway. They did this during the busy morning rush hour.

Members of the group used a deadly gas called sarin. They released it on three different train lines. This attack killed 14 people. It also hurt many others. Nearly 1,000 people had problems with their vision.

The group wanted to stop a police raid. They also wanted to start a war. After the attack, the police worked hard. They arrested more than 200 members. They even caught Shoko Asahara.

Many leaders were sent to prison. Some were even put to death. This was a very dark time for the city of Tokyo.

In March 1995, a very serious event happened in Tokyo, Japan.

A group called Aum Shinrikyo carried out a chemical attack. They used a dangerous nerve agent called sarin. This attack took place on the Tokyo subway system. It happened during the busy morning rush hour. The goal was to strike near the National Diet. This is the place where the Japanese parliament meets.

The event remains the deadliest terrorist incident in modern Japan.

The attack worked through five coordinated actions. Members of the group released sarin on three different subway lines. They targeted trains passing through Kasumigaseki and Nagatachō. The gas caused many people to get very sick. This attack killed 14 people in total. It also caused severe injuries to 50 others.

Nearly 1,000 people suffered from temporary vision problems. The sudden release of the gas caused chaos in the stations.

This group started as a small yoga class in 1984.

A man named Chizuo Matsumoto founded the group. He later became known as Shoko Asahara. The group grew very fast over many years. By 1992, they had about 20,000 members. Their wealth also grew from very little to a huge amount.

Asahara led the group with many strange beliefs. He believed a global war was coming soon.

Asahara and his followers tried many different things before the subway attack. They tried to make biological weapons like anthrax.

These early attempts mostly failed to cause harm. They even tried to spray a liquid from trucks. They also tried to use a homemade sprayer on a car.

These efforts did not work as they planned. Eventually, they turned their focus to making chemical weapons. They built a laboratory in a place called Kamikuishiki.

This event changed how people thought about safety in cities. The police worked hard to catch those responsible. They arrested over 200 members of the cult.

This included the leader, Shoko Asahara. Many senior leaders were sentenced to death. Others were given long prison sentences. Today, the history of this attack is remembered as a very dark time. It shows how much harm can come from dangerous ideas.

On March 20, 1995, a major chemical terrorist attack occurred in Tokyo, Japan.

The attack was carried out by members of a religious cult known as Aum Shinrikyo. They used a highly dangerous nerve agent called sarin. This substance is a chemical that attacks the nervous system. The perpetrators coordinated five separate attacks on three different lines of the Tokyo Metro. These attacks took place during the morning rush hour when trains were very crowded. The primary targets were trains passing through the Kasumigaseki and Nagatachō areas. These locations are significant because they are near the National Diet, which is the Japanese parliament. This event remains the deadliest terrorist incident in Japan by modern standards.

The mechanism of the attack involved the intentional release of liquid sarin onto the subway trains.

Once released, the chemical caused immediate and widespread harm to passengers. The attack resulted in the deaths of 14 people. It also caused severe injuries to 50 individuals, some of whom later died from their wounds. Additionally, nearly 1,000 people experienced temporary vision problems due to exposure. The coordination of the five attacks across different lines maximized the chaos within the city's transit system.

The suddenness of the chemical release made it difficult for passengers to react or escape.

Aum Shinrikyo began in 1984 as a small yoga and meditation class.

It was founded by a pharmacist named Chizuo Matsumoto, who later took the name Shoko Asahara. The group's beliefs were a mixture of Indian and Tibetan Buddhism, Christianity, and Hinduism. Asahara claimed to be a divine figure with the power to transfer spiritual strength to followers. The group grew rapidly after receiving official religious status from the Tokyo Metropolitan Government in 1989. This status provided tax breaks and limited government oversight. Membership rose from about 20 people to approximately 20,000 by 1992. Their wealth also increased significantly, growing from very little to a massive amount of money.

Before the subway attack, the cult attempted to develop several types of biological weapons.

They tried to produce substances like botulinum toxin and Bacillus anthracis, which is known as anthrax. These efforts were largely unsuccessful because the group could not properly purify the substances. For example, they produced a crude broth of botulinum that was not toxic enough to cause harm. They also attempted to use a vaccine strain of anthrax, which is unable to cause disease in humans. One attempt even involved spraying a substance from a truck, but it caused no harm to the public.

These failures led the group to shift their focus toward chemical weapons.

The shift to chemical warfare was led by Masami Tsuchiya, who established a laboratory in the Kamikuishiki complex.

Tsuchiya suggested that sarin would be the most cost-effective substance for the group to manufacture. This chemical division focused on synthesizing nerve agents to achieve their violent goals. The group used various facilities to build up their stockpiles of dangerous chemicals. They even attempted to produce other agents like VX and chlorine gas. The group's transition from failed biological experiments to successful chemical production marked a dangerous escalation in their capabilities.

The subway attack was motivated by specific fears held by the cult's leadership.

Shoko Asahara had learned that a police raid was scheduled for March 22, 1995. He ordered the subway attack to hinder the police investigations into the cult. He also believed the attack might help trigger a predicted global apocalypse. Following the attack, police activity was intense throughout the summer. They arrested over 200 members of the cult, including Asahara himself. Thirteen senior members of the group's management were eventually sentenced to death and executed. Many other members received long prison sentences, including life in prison.

The history of Aum Shinrikyo is a study of how extremist ideologies can lead to organized violence. The group's attempt to seize power through both political and violent means shows their complex structure. They ran 25 candidates in the 1990 Japanese Diet election, but they received only 1,783 votes. This political failure contributed to the group's decision to use terrorism to overthrow the government. The attack serves as a critical example of the dangers posed by domestic chemical terrorism. It also highlights the importance of government oversight and the monitoring of extremist groups in modern society.
