Every two years, the automotive world descends on Tokyo to present its vision for the vehicles we'll be driving in years to come. 2013 is the 43rd Tokyo Motor Show, and a host of carmakers from around the world such as BMW, Tesla, and Mercedes-Benz joined the likes of Honda, Toyota, and Nissan on their home turf.

Perhaps not surprisingly, there has been a heavy focus on electric vehicles at this year's show, with most manufacturers having some form of hybrid or electric model on hand. And, with eyes firmly looking forward, some companies have used the opportunity to show off some of the most unusual designs we've ever seen on ostensibly road-legal vehicles, such as Nissan's BladeGlider (above). Read on to see these, along with some traditional supercars, unorthodox farm equipment, and a few nods to the past.
