This roller coaster in Yokohama. "Japan". It goes under water and maybe its the best roller coaster in Japan. Yokohama is a popular city in Japan. There is a lot of shopping places and the best amusement park in Japan. In Yokohama amusement park there is many roller coasters, horror games, and fun games. The tower in the picture behind the roller coaster is a Inter Continental Yokohama Grand a five stars hotel. I recommend you to go Yokohama.
