For a limited time this winter, the entire 52nd floor of the Roppongi Hills Mori Tower will be turned into a train-themed wonderland, perfect for all railway-lovers. This huge undertaking is possible thanks to all seven parts of Japan Rail and the Tokyo Metro, along with private railways and the Tokyo Metropolitan Bureau of Transportation, all working in cooperation. Life-size recreations of historic train stations, rare memorabilia, train-themed art, modern hands-on exhibits of all kinds, and much more come together to create a spectacular special exhibition, all about trains.
