"Many good things come in small packages
Owning a city car, also called a Kei car, in Japan has distinct advantages: They are allowed up to 660cc engines and thus are fuel efficient, they’re limited to 3.25 feet in width and 7.5 feet in length, so are small and easier to park, and the government makes them vastly less expensive to register and inspect than larger cars. As a result, most automakers make one or several models and you can get just about anything in Kei form: vans, cabriolets, sports coupes, dump trucks, AWD, twin-charged rally machines, and rock crawlers. Unsurprisingly, people modify the snot out of them.
Perhaps because of the demise of the Japanese supercar (the Supra, RX-7, and Skyline all ceased production around the same time), there was for the first time an abundance of Porsches and BMWs on display, as well as Japanese tuners directing their parts towards this market. The EVO remains a popular candidate for every imaginable performance and aesthetic enhancement, with not as many competing Subaru STIs stationed around the show as in years past. The drifting phenomenon, whose initial surge in the United States is ebbing slightly, remains a hot ticket in Japan, and competitor’s cars were constantly mobbed.
Nobody does specific engine output like the Japanese, stock or modified, and absurd horsepower figures were spread thick through the show. Over 300 horsepower, from naturally aspirated four-cylinder engines was not uncommon (yes, their pump gas has a higher octane rating than ours), and there was a bevy of inline and V-6s with forced induction approaching the millennium horsepower mark, all without the help of nitrous oxide."
