On July 26, 2018, the remaining six members of Aum Shinrikyo on death row were executed. These executions were part of the final chapter in the legal proceedings against those responsible for the Tokyo subway sarin attack. The executions were met with mixed reactions in Japan and abroad.

Shoko Asahara was executed on July 6, 2018, along with six other senior members of Aum Shinrikyo. The executions marked the end of a long legal process and were carried out in secrecy. The event brought closure to one of Japan's most notorious criminal cases.

On February 27, 2004, Shoko Asahara was sentenced to death by the Tokyo District Court. He was found guilty of masterminding the Tokyo subway sarin attack and several other crimes. His trial lasted nearly eight years, and the verdict was a significant moment in Japan's legal history.

Shoko Asahara, the leader of Aum Shinrikyo, was arrested on May 16, 1995, following a nationwide manhunt. His arrest marked a significant turning point in the investigation of the Tokyo subway sarin attack. Asahara was found hiding in a secret compartment in the cult's headquarters.

On March 20, 1995, Aum Shinrikyo members released sarin gas on five trains in the Tokyo subway system during rush hour. The attack killed 13 people, severely injured 50, and caused temporary vision problems for nearly 1,000 others. It was one of the most serious attacks on Japanese soil since World War II.

The Matsumoto sarin attack was a precursor to the Tokyo subway attack. On June 27, 1993, members of Aum Shinrikyo released sarin gas in the city of Matsumoto, Nagano Prefecture, targeting judges who were overseeing a lawsuit against the cult. The attack killed eight people and injured over 500.

Aum Shinrikyo, the cult responsible for the Tokyo subway sarin attack, was founded by Shoko Asahara in 1984. The group initially started as a yoga and meditation class but gradually transformed into a doomsday cult with apocalyptic beliefs. Asahara claimed to be Christ and sought to take over Japan and the world.
