Tldr: In 1970s Japan, Mitsuyasu Maeno was a Japanese pornstar with Ultranationalist leanings. He was disillusioned by Yoshio Kodama, a fellow ultranationalist and underworld figure, when it was discovered that he played a part in the Lockheed bribery scandal of 1976. Thinking that Yoshio betrayed the country by consorting with American interests and dishonouring the Samurai code, he decided to get revenge by flying a plane, Kamikaze style, into Yoshio’s mansion. Yoshio however survived because he was in another room, but Maeno perished.
It’s one of the least effective methods out there
