A man was taken to a hospital in an unconscious state on Wednesday after he allegedly set himself on fire near the office of Japanese Prime Minister Fumio Kishida.
Initial details about the incident in Tokyo were scant, and police and the prime minister’s office declined to comment.
TV Asahi said the man set himself on fire after telling police that he was opposing plans for a state funeral for the assassination of former prime minister Shinzo Abe.
The television station said a police officer trying to douse the fire was injured in the process.
The Kyodo news agency and other outlets said police were called to the scene after reports of a man “engulfed in flames”.
It said a note was found near the person, expressing opposition to the funeral.
Abe, Japan’s longest-serving prime minister, was shot dead during an election campaign on July 8, and a publicly funded funeral will be held in his honor on September 27.
But state funerals are rare in Japan, and the decision has been controversial, with polls showing nearly half the public opposing the idea.
