Seems like I need to find a reason to travel to Japan, this thing looks like a beast.

The fierce Kingda Ka is simply the tallest, fastest roller coaster on Earth. This remarkable thrill ride breaks all world records for coaster speed and height, zooming from
0 to 128 mph in 3.5 seconds and catapulting you 45 stories into the sky.


I finally got to ride this... thought I would be scared... but was not... incredible ride - 128 MPH is kinda a thrill on a roller coaster.....

Nice...  Only downside I see is the limited duration of that ride.

What really caught my eye with that coaster in Japan were the pivoting seats, which has got to provide some very unique views/feels during the ride.
