The Kyoto Animation arson attack (Japanese: 京都アニメーション放火殺人事件, Hepburn: Kyōto Animēshon satsujin hōka jiken) happened at Kyoto Animation's Studio 1 building for anime in the Fushimi-ku ward of Kyoto, Japan, on the morning of 18 July 2019.

The arson killed at least 36 people, injured 34, and destroyed all materials and computers in Studio 1. It is one of the deadliest killings in Japanese history since the end of World War II and the deadliest building fire in Japan since the Myojo 56 building fire in 2001.

Many heads of state have expressed condolences, including António Guterres, General Secretary of the United Nations. And many donations and massages have send to victims of the arson attack.
