The arson act at the offices of the anime studio Kyoto Animation, sometimes referred to as "KyoAni," that occurred on July 18, has been widely reported by media worldwide. The attack resulted in the deaths of 35 people with another 33 injured, and is one of the worst incidences of violence that has resulted in death or injury to happen in Japan.

The attack has grim echoes of the Sagamihara massacre, when on July 26, 2016, a former care worker at the Tsukui Yamayuri-en care home for the disabled in Sagamihara, Kanagawa Prefecture, killed 19 people and injured 27 others.

A suspect in the KyoAni attack was arrested the day after the incident, and was taken into custody and then to the hospital as he had sustained severe burns himself. The police were unable to question the suspect as he was sedated, but details soon began to emerge.
