We'd never heard of this place before but decided to try it out since it's in the middle of Tokyo and relatively easy to get to. The pass allows you to ride any 4 attractions and get admission to the space museum. Given that the price of each ride ranges from 420 yen to 1030 yen, and admission to the museum is usually 1800 yen for an adult, this not a bad deal at all. The roller coaster is actually pretty high and steep, and there is enough variety of attractions to keep you entertained for the day. We thought the Haunted Mansion was pretty cool too! There are also heaps of rides the kids can enjoy so families who want more tame rides can also make good use of this pass. The space museum is interactive and worth going to as well. Would definitely recommend people who have a spare day in Tokyo to try out this retro feel theme park!
