Welcome to the Takeshi's Castle, a Japanese game show involving 100 to 140 contestants who try to go through a series of silly physical challenges designed to eliminate them. Designed like a live-action Mario game, thousands of people have come to take on Takeshi's Castle to try and win the ¥1,000,000 prize but hardly anyone does! Each episode was filmed over the entire length of the day, with some challenges going well into the night.
