A man in his late 50s or 60s set himself on fire at Tokyo's busy Shinjuku railway station on Sunday in what appears to be a rare violent political protest, according to The Associated Press.
The man was taken to the hospital after suffering serious injuries, said Daiji Kubota, an officer at the Shinjuku police station, the AP reported. He said the man's identity and the reason for the self-immolation was under investigation.
Footage of the incident on Twitter and other social media showed a man clad in a suit and tie sitting on a small mat along the metal framework above a pedestrian walkway with two plastic bottles of what looked like gasoline beside him, according to the AP.
Witnesses were quoted as saying the man spoke through a megaphone to protest the government's moves to change Japan's defense policy, doused himself with gasoline and set himself alight as hundreds of people watched from below and from nearby buildings, the AP reported.
Television reports showed firefighters pulling the man down onto the pedestrian bridge walkway and using hoses and a fire extinguisher to put out the fire before loading the victim into an ambulance, according to the AP.
Japan's Cabinet is expected on Tuesday to approve a proposal calling for the right to "collective self-defense," which would allow Japan to play a more assertive role in international security amid China's growing military presence and rising regional tensions. Japan currently limits its participation even in U.N. peacekeeping activities to noncombat roles, the AP reported.
Critics say the shift undermines the war-renouncing Article 9 of Japan's Constitution, and opposition groups have staged constant but peaceful protests outside Prime Minister Shinzo Abe's official residence, according to the AP.
Japan has had very few self-immolations in past decades despite a long history of suicides by ritual disembowelment, or seppuku, dating back to the feudal era, the AP reported.
The most high-profile suicide for political reasons in the modern era was by Yukio Mishima, a right-wing author considered to be one of Japan's greatest novelists, who killed himself in front of the headquarters of Japan's Self Defense Forces in 1970 after an unsuccessful coup attempt, according to the AP.
