If you are in search of the fastest, most modern roller coasters in the world…you may want to skip Japan. With few exceptions, amusement park rides in Japan are about equivalent to state fair rides in America. This means Japanese amusement parks have to be a little more creative with their marketing. For example, Toshimaen, a western Tokyo amusement park, has on onsite onsen (hot springs) and a popular summer water park. It also has seasonal illuminations for cherry blossom viewing and December holidays as well as stunning fall foliage of ginko and maple trees.
