The new Japanese maglev became the fastest train in the world after traveling at 374 miles per hour (603 kilometers per hour)

In 2020, the Japanese capital will host the Summer Olympics, and if you're getting deja vu that's because the Asian nation is once again shattering rail records.

The new Japanese maglev became the fastest train in the world after traveling at 374 miles per hour (603 kilometers per hour) on a test run near Mount Fuji last year, breaking its own world record of 366 miles per hour (590 km per hour), set the previous week.

Maglev trains -- already operating at slower speeds in Shanghai and Changsha, in China, and Incheon, in South Korea -- use magnetic repulsion both to levitate the train up from the ground, which reduces friction, and to propel it forward.
