The Yamanashi Prefectural Maglev Exhibition Center explains the technology behind Japan's Linear Chuo Shinkansen, the magnetic-levitation line planned between Tokyo and Osaka. Displays cover the trains, superconducting magnets, and the test track that runs through this part of Yamanashi.
The big draw is the chance to see test runs when they are scheduled. Check the running calendar before making a special trip, as the centre is much more interesting when the trains are active.
