Tokyo Xtreme Racer

The series was originally subtitled "Drift King", after the trademark nickname of street racing and professional racing driver Keiichi Tsuchiya who is featured in the first Shuto Kousoku Trial episodes and endorsed the game with, then team manager, Masaki Bandoh of Bandoh Racing Project.

During the 1990s Genki produced a highway drift/adult content (omitted in the localization Highway 2000) oriented Shutokou Battle spin-off series for the Sega Saturn, Wangan Dead Heat, and a circuit/tune edition unique episode for the PlayStation, Kattobi Tune, which oriented the Shutokou Battle series through a new direction, leading to the Dreamcast version and its worldwide recognition and distribution. "Kattobi Tune" was compiled under the supervision of Rev Speed, a popular Japanese car tuning magazine and features seven licensed professional tuners, RE Amemiya, Spoon, Mine's, Trial, "RS Yamamoto", Garage Saurus and JUN Auto, appearing years later in Racing Battle: C1 Grand Prix and also in the influential Gran Turismo series by Polyphony Digital.

Though the entire Shutokou Battle series has been referred to as the "Tokyo Xtreme Racer" series in the west, only a subset of games had an official "Tokyo Xtreme Racer" title attached. The games also received different names in different regions, adding to confusion.

Kaidō Battle (街道バトル) is a spin-off series for the PlayStation 2 created by Genki. They are focused on Touge racing and heavily centered on drifting. The franchise currently has three games, with two of them being released in North America under the Tokyo Xtreme Racer banner by Crave Entertainment.

The series, like the main Shutokou Battle games, includes licensed cars and authentic Japanese mountain roads as courses. In Conquest Mode, the player competes during the day in drift contests, earning more points for holding a drift longer or for a quick combination of drifts, but earns no points if the player bumps against the wall or a guard rail. Doing this, the player earns money to buy new cars and modifications. Daytime racing also features racing for sponsors, which includes a kind of racing challenge determined by the sponsor. Beating a sponsor challenge earns the player a sponsor. Sponsors give the player better parts and extra bonuses for winning drift contests.

At night, the player can challenge rivals in the parking lot, and race them in a vein similar to Shutokō Battle/Tokyo Xtreme Racer: the first one to have their life bar depleted loses; however, the first racer to cross the finish line will win the race. Through the night, the player will face the "Tricksters", a type of mini-bosses in the course. After all the Tricksters have been beaten, the main boss of the course (called the "Slasher") will challenge the player through an in-game BBS system. After the Slasher has been beaten, the player may advance to the next stage. The final boss in the last course is called the "Emotional King."

The story unfolds in Kaido Battle when Hiroki Koukami challenges and defeat all Slashers, including Motoya Iwasaki, the Speed King from Shutokou Battle, until he challenges Hamagaki, the Kaido President & 1st Emotional King in his yellow Pantera GTS at Irohazaka. By doing so, Koukami becomes the new Emotional King, while Hamagaki becomes a Trickster.

In Kaido Battle 2: Chain Reaction, Tatsu Zoushigaya arrives at the age of just 18. Like Koukami, he beats all Slashers and eventually Koukami himself in his Lancer Evolution 3 at Aso, Hamagaki in his Genki S2000 Turbo, as well as the secret rival Ground Zero Kazioka in his Skyline GT-R. But since he was defeated, Koukami moves away to Hokkaido and the Kaido Circuit spirals into chaos.

To fix it, in Kaido: Tōge no Densetsu, Zoushigaya becomes the Miracles Summit and now drives a black Subaru Impreza Prototype Rally Car and Kyoichi Imaizumi, Zao's Slasher, becomes the Absolute Emperor and drives a white Renault Clio V6 Phase 2. These drivers are now the fastest on the Kaido Circuit. Meanwhile, the 13 Devils from Tokyo led by Iwasaki come to the Kaido Circuit and have the intention to conquer it. In order to protect the circuit from the Devils, they create another team: The Kingdom Twelve. At the beginning, their leader's identity is unknown.

This time, the hero is also unknown and is able to beat everyone, even Imaizumi and Zoushigaya. By beating them, he is able to defeat the members of the Kingdom Twelve & the 13 Devils. By e-mails, the Kingdom Twelve's leader's identity is known after he beats Timberslash: Hamagaki. After beating him and Iwasaki, the hero battles Koukami and beats him. And after these events, the truth is revealed: Hamagaki was still angry since he lost his title as the Emotional King.

Thus, in Kaido Battle 2: Chain Reaction, he challenged every rival and eventually challenged Koukami again at Aso. But Koukami won again, making Hamagaki angrier than ever. Eventually, since Iwasaki became depressed, Hamagaki cajoled him to race into the Kaido Circuit, but by doing so, he manipulated him, and lies to everyone saying that his team protects the Circuit from the Devils, while the Devils didn't know his real goal: to found the fastest Rally Team and Highway Team.

The D1 Grand Prix drifting championship inspired the new series Racing Battle: C1 Grand Prix, released in 2005 and remembering the 1997 drift circuit based Shutokou Battle Gaiden and the continuation of the "Shutokou Battle circuit + RPG" concept introduced in Kattobi Tune,[1] a genre close to the Zero4 Champ series by Media Rings.

The first and only episode has the tagline "C1 Grand Prix", which is a double reference to the D1 GP and the Route C1, the latter being the Inner Circular Route of the Shuto Expressway and the circuit for most episodes of the Shutokō Battle series.
