Tsunami be damned, the Japanese are back and ready to build something better than America.  Check out the steepest roller coaster in the world "Takabisha".

 

I've been to Cedar Point about a million times and nothing in that park, even the Millennium Force has anything on this beast.  I think it's sweet how they put the steepest hill in the world halfway through the ride. At its worst, you're going down a 141 foot hill, at 121 degrees, at 62 miles per hour.   That's some scary math.
