Streets Ahead is an obstacle course first played on the original version of Takeshi's Castle.
Two contestants at a time race each other through this obstacle course.
Dressed in fat sumo costumes, the contestants have to first jump over five mini-hurdles, and then walk along a balancing beam. Once over the beam, they need to take the costume off and climb over a wall, using a ladder to get down on the other side.
Next there are two giant plastic satchels on the ground. The contestants each need to pick one up, put it on their back, and walk over to a tray on the floor.
On the tray are three marshmallows. Only using their mouths, the contestants have to pick up all three marshmallows before they can move on. When they've got them in their mouth it's a run to the finish line.
The 7 fastest men and the 3 fastest women to finish the course move on to the Midoriyama round.
