A series of racing games by Genki, known also in Japan as ''Shutokou Battle'' and dating to the SNES days, although few of the earlier games made it to the United States. It got more notice when the SegaDreamcast versions came stateside. (Genki also developed the first ''Manga/WanganMidnight'' console games.)

The main feature of the game is its free roaming environment (not introduced until the first Dreamcast game) and the "SP" system, in which both your car and the opponent's car have life bars that go down when either car is ahead or hits a wall/civilian traffic.

List of the games in the series (note that localized releases are listed by their English titles):
* ''Drift King Shutokou Battle '94'' (Super Famicom, Japan-only)
* ''Drift King Shutokou Battle 2'' (Super Famicom, Japan-only)
* ''Highway 2000'' (Saturn, known as ''Wangan Dead Heat'' in Japan)
* ''Tokyo Highway Battle'' ([=PlayStation=], known as ''Shutokou Battle: Drift King'' in Japan)

----
!! The ''Tokyo Xtreme Racer'' series contains examples of the following:
* BossGame: ''Kaido Battle'' series as well as ''Racing Battle: C1 Grand Prix''.
** Also applies to ''Drift King'' titles where Keiichi Tsuchiya is the BigBad of these games.
* BossBonanza: Some bosses in [=TXR3=], and Phantom Nine in ''Import Tuner Challenge''.
* BossRush: In later parts of every Shutokou Battle games, especially against Nagoya bosses in TXR 3.
* {{Cap}}: On your speed; ''[=TXR0=]'' caps you at 430 km/h / 267 mph, and ''[=TXR3=]'' to 370 km/h / 230 mph.
* CulturalTranslation: The North American version converts all measurements to U.S. measurements, ''even though the game is set in Japan''. Also see the RaceLift example below.
* EasyModeMockery: Some games have an "easy" life meter option in which you only lose SP for trailing (as opposed to losing SP for trailing as well as hitting stuff). However, using this option reduces the amount of currency won from battles.
* FourIsDeath: In the first ''[=TXR=]'' game, there are two racing teams whose name starts in "Four" ([[QuirkyMiniBossSquad Four Devas and Four Devils]]), consisting of four members each. In ''[=TXR0=]'' and ''Import Tuner Challenge'', the number for the final boss is "400", connecting the number "4" to the unlucky and demonic number.
* GameBreakingBug / UnwinnableByMistake: Due to an error involving converting currency, one opponent in ''Tokyo Xtreme Racer 3'' requires you to have more money than is [[{{Cap}} permitted]]. And she's one of the 599 opponents you need to defeat to challenge the GiantSpaceFleaFromNowhere FinalBoss. As a result of this hard lesson learned, every subsequent localization of any Shutokou Battle / Kaido Battle game leaves the currency as is.
* GiantSpaceFleaFromNowhere: The final boss in ''[=TXR3=]'', and Twenty Masters in ''Drift 2''.
* GuideDangIt: Many of the requirements to summon and/or be able to challenge "Wanderer" opponents. In ''[=TXR3=]'', some of the opponents' requirements are hinted at in their profiles, but for many others, as well as those in other games, you may as well hit up a guide.
* HeroicRROD: In ''[=TXR3=]'', driving for too long without stopping occasionally in the parking areas results in drastically reduced engine performance (from water and oil temps overheating). Driving for too long in a single night will also wear down your tires and make the car less responsive to steering inputs, and have less grip overall.
* InUniverseGameClock: The ''Shutokou Battle'' games have in-game clocks that are tied to the system clock and are used for some events, such as Wanderers that only appear at a particular time. However, this is subverted due to...
** TheNightThatNeverEnds: It is always nighttime, whether you're playing at 10 PM, 5 AM, or even noon.
* JapaneseRanguage: At least in ''Tokyo Xtreme Racer: Drift 2'', you can apply a stripe to your car. Among the options such as "Stripe", "Brush" and "Wild", there is a "Frame" option. Every single stripe in the option looks like a ''Flame'' stripe.
* LifeMeter: The SP gauge system.
* MirrorBoss: In ''Tokyo Xtreme Racer 3'', [[spoiler:the GiantSpaceFleaFromNowhere FinalBoss is a [[http://www.youtube.com/watch?v=iDc3a2gLtbY#t=3m37s ghost copy of your own car]].]]
* [[OneManArmy One Driver Army]]
* QuirkyMiniBossSquad: Thirteen Devils, Zodiacs and Kingdom Twelve.
** In the first Dreamcast game, there are Four Devas and Four Devils.
** [[BossBonanza Phantom Nine]] in ''Import Tuner Challenge'' does count.
* RaceLift: Many characters in ''[=TXR0=]'' had their names changed from Japanese names to Western names. The result: [[FridgeLogic Tokyo's highway racing scene is comprised mostly of Westerners.]]
* RainOfBlood: In ''[=TXR3=]'', if you race Blood Hound in the rain, the rain turns into blood.
* TheRival: For Kaido Battle series, it's GranTurismo series, except you're on the tracks instead of mountain roads.
** ''Racing Battle: C1 Grand Prix'' also shares this.
** The earlier ''Shutokou Battle'' games prior to TXR series have in common with RidgeRacer games at that time.
* ShoutOut:
** The top two members of Rotary Revolution [[InitialD are brothers and drive a white RX-7 FC and yellow RX-7 FD]]. Which makes sense as the cover car that can be used at the start is an AE86.
** The FinalBoss of ''Tokyo Xtreme Racer Zero'' and ''Import Tuner Challenge'' is [[spoiler:[[WanganMidnight a dark blue Fairlady Z S30 with insane horsepower and manaical handling]].]]
*** Averted in ''Drift 2'' where one of the regular rivals use this type of car with reduced performance.
** Most of the "cheat names" you can enter at the start of your career in Kaido Battle 3/[=TXR=]:Drift 2 are names of various InitialD characters.
** Red Devil's red [=R34=] makes reference to the various mobile suits piloted by [[MobileSuitGundam Char Aznable]]. In some games, he simply sticks a Commander Zaku's horn on the hood. In Street Supremacy, he models it after Char's Z'Gok E. The variant you can unlock for purchase has the Z'Gok E's standard steel blue paint.
* TerribleTrio:
** The Rook, The Bishop, The Knight.
** Yeti Fang, Reign Supreme, Forever Knights.
* TrueFinalBoss: In ''Drift 2'', when you defeated the Blackout (Forever Knights in the Japanese version), the Emotional King (final boss) in Hokkaido area of the game, the game isn't completed yet. Ground Zero is waiting for you in Hakone where you have started off, while it's stormy there.
* WideOpenSandbox: When you're not racing opponents, you're more or less free to drive around the city with impunity, unless you're playing a game with water and oil temperature as gameplay mechanics, and even then a quick pit stop will remedy that.
* YouAllLookFamiliar: It is a coincidence that both ''DaytonaUSA 2001'' and the TXR games are developed by Genki.
** Even cars in ''Daytona USA 2001'' do resemble Japanese cars. For example, the Red Cat resembles a mix of Honda NSX and Mitsubishi GTO, while Hornet resembles more like a Nissan Skyline GT-R.
