Mazda's corporate headquarters are a short distance outside of Hiroshima. The tour is a must for any automobile fan, but if you have any serious technical questions, then you should go on the Japanese tour and bring along your own interpreter, as there's less detail on the English tour. Highlights include the Mazda Cosmos (the world's first car with a rotary engine) and the 4-Rotor Mazda 787B, which is the only Japanese car to win at Le Mans. From there you will be taken to their Ujina plant and the actual assembly line, with a look at some of their concept vehicles. From JR Hiroshima Station, take the San'yo Line in the direction of Saijō or Mihara to JR Mukainada Station (two stops); cross the rails and exit through the south exit. From the train station exit, head straight on the street a little to the right of the exit until you see the confusingly labelled pharmacy, called "Zoom-Zoom". Head down the stairs opposite Zoom Zoom into an underpass and you'll exit in the Mazda Admin building's parking lot.
