Kanye West has lost a $20 million deal to play in Japan as a result of his controversial stunt at the Grammys, according to sources in Tokyo. West, 47, had signed up to do two shows at the Tokyo Dome in May, but following the naked stunt on the red carpet of the Grammys on Sunday night with his wife Bianca Censori, his investors have taken fright. A source said: 'Kanye is just ****ing up every opportunity that comes to him. The stunt was creepy beyond belief and has been greeted with horror in Japan.'
