This prank is from the Japanese game show Dokkiri Award (with 'Dokkiri' meaning "to be surprised"). Comedian Toshiaki Kasuga went to work near the base of Mt. Fuji, and after a night of drinking, passed out in the bed of his rental cabin.
Because he was in a drunken stupor, he was able to sleep through the show's prankster crew setting up what would undoubtedly be the rudest awakening in the history of ever.
