I Survived a Japanese Game Show

In the Season 1 finale, the winner emerges from among the four remaining contestants. In one of three challenges, they hit the streets of Tokyo and must persuade strangers to do such things as draw mustaches on their faces. The survivors must then jump into a giant water-filled bowl dressed in sponge suits and retain as much water as possible while negotiating an obstacle course. Then there's yet another obstacle course, this one combining challenges from previous contests on the series.
