Import Tuner Challenge
2006 video game
Import Tuner Challenge is a 2006 racing game published by Ubisoft and developed by Genki for the Xbox 360. It is an installment in the long-running Shutokō Battle series of games known as Tokyo Xtreme Racer in North America and Tokyo Highway Challenge in Europe. This is the only Shutokou Battle game to be released on the Xbox 360.
Plot
After the 13 Devils have been defeated once more in the Kaido Circuit, Motoya Iwasaki, aka Speed King, disappeared suddenly, leaving without a trace. Since then, many drivers from all across Japan come to Tokyo in order to have his title of "Speed King", especially the Japanese-American racer, Snake Eyes, and his team, Phantom 9, which later began an all-out assault on many teams in the Shuto Expressway following Speed King's absence, and his return to Tokyo, after five years of racing in America.
The player assumes the role of Ren Tennoji, Iwasaki's best friend, who sets out to defeat numerous teams and rivals, including Bloodhound, Midnight Cinderella and Platinum Prince, and much later on, Skull Bullet, an American racer who came to Tokyo in pursuit of Snake Eyes.
It is later revealed in the story by Bloodhound that Iwasaki disappeared from the Shutokou due to the passing of his girlfriend from a terminal illness three years prior to the events of the game, and went into hiding as he later became disillusioned with street racing and went on a major identity crisis as a result of her death.
Shortly after Tennoji defeats Snake Eyes, Iwasaki reveals himself as Speed King once more and thanks Tennoji for reviving his passion for racing, and decides to return to the Shuto Expressway once again. Tennoji later finishes off loose ends and eventually defeats Speed King and ultimately "???" (Unknown), solidifying his status as the best racer in the Shuto Expressway.
It is revealed in the sequel, Tokyo Xtreme Racer (2025), that Tennoji inherited the title of Speed King from Iwasaki.
This brief starts where responsible research should: with the source description of “Import Tuner Challenge” as 2006 video game. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 2006 video game. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q6007407. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006 and 2025.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
