3DS Neo Bowser City

Neo Bowser City (known as Koopa City in the British English version) is the third course of the Star Cup in Mario Kart 7. It takes place in a rainy, neon-lit city themed after Bowser, the only Bowser-themed course to not be a version of his castle. Neon signs are everywhere and images of Bowser himself and his signature emblem can be seen in various places. It is the second course in the Mario Kart series that takes place entirely in the rain, the first being Luigi Circuit from Mario Kart: Super Circuit.

Neo Bowser City also appears as a retro course in Mario Kart 8, Mario Kart 8 Deluxe, and Mario Kart Tour. In the former games, it is the first course of the Bell Cup, a cup that comes with the Animal Crossing × Mario Kart 8 add-on content pack for the original Mario Kart 8, while in the latter game, it was introduced in the Tokyo Tour.

Notably, the course's music quotes themes from several other Mario Kart courses: the Toad Circuit and Mario Circuit theme from Mario Kart 7, the Luigi Circuit and Mario Circuit theme from Mario Kart Wii, and the Toad's Turnpike theme from Mario Kart 64. The theme was reused in the arrangement entitled "Circuit (Mario Kart 7)" in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate.

Mario Kart 7
This course takes place in a brightly lit city in the rain. A large percentage of the course is winding roads with moving neon arrow railings. There is a small upward spiral section in the middle of the track that goes up a tower. Traction is decreased due to the rain. There is a tunnel close to the end of the course, that leads to a road that is covered with puddles. A Glide Ramp then appears just before the end. A billboard is seen near it with a picture of either Bowser (said picture is his artwork from Mario & Sonic at the Olympic Winter Games), the player's view, or an animated "Overtake" ad from Toad Circuit. If gliding players veer left (right in mirror mode) from the starting line, they can fly over a Koopa Clown Car with a fan to give them lift enough for the first bend; in higher engine classes, however, they must steer back quickly to avoid hitting the wall.

Course layout
The course starts with an S-bend; however, players must steer back in quickly to avoid hitting the wall. Just before the player enters the air vent area, it is possible to be pushed through the guardrails by a heavier opponent. After that, the race continues under a tower with air ducts. Then there are two soft turns and a red tunnel. After many turns, the player exits and reaches the winding part of the road, which consists of three hairpin turns. Then, there is a shorter tunnel that leads to a road all to the left, that is covered with puddles. At the end, there is a glider ramp back to the finish line.

Shortcuts

 * After the S-bend, players can cut through the mud with a Mushroom. They must steer back in quickly to avoid hitting the wall.
 * Near the finish line, if players use a Mushroom or the Koopa Clown Car air current, they can glide through a secret zone on the S-bend under the red tunnel.
 * The last U-turn of the middle section with no railings can be skipping by drifting off the edge to to cut the gap. This is not very viable for races as it saves a minimal amount of time whilst also being very risky, due to it being very precise; a sign with Bowser's head on it can block the way and cause the player to fall out of bounds.
 * A glitch shortcut can be performed on the secret zone below the S-bend. By landing on it, turning around, leaning backwards off the edge of the area (which is heavy off-road) to gain an upwards angle and using a Mushroom, it is possible to go through the bottom of the bridge and land on it. If done quickly this saves around six to seven seconds.

Staff ghost
The normal staff ghost for this course is Metal Mario, using the Standard Kart, Standard tires, and Super Glider. The expert staff ghost is again Metal Mario, though instead using the Blue Seven, Monster tires, and Parafoil.

Mario Kart 8 / Mario Kart 8 Deluxe
Neo Bowser City returns to Mario Kart 8 as a retro course in the second DLC pack Animal Crossing × Mario Kart 8 and as part of the base content of Mario Kart 8 Deluxe. It is the first track of the Bell Cup. The city background is given an overhaul in design, featuring a glass tunnel where anti-gravity vehicles are driving in, and with more distinctive architecture, instead of having mushroom hills on the far background. The start and finish banner has been redesigned, featuring hexagon patterns behind the Mario Kart logo, and on the two neon pillars (previously one) supporting the banner. It is also possible now to hit the banner, like in Mario Circuit and DS Wario Stadium. Unlike on the other two courses, though, the banner for this course spins when hit, whereas the other courses' banners only swing.

The new Bowser insignia that is now used in this course is also modeled around a hexagon. The blimp with a screen on it has been removed. Billboards now show an animated picture of the name of the course, along with Bowser in it, instead of displaying an ongoing video of the player's point of view, an animated ad, and a still picture of Bowser. The signs and animated picture display the text "Neo Bowser City", even in non-American versions, where the name of the course is different. A similar discrepancy occurs in 3DS Music Park (called "Melody Motorway" in the British English version). The rails with scrolling neon arrows have been redesigned into neon rails with light arrows on top of them.

The overall course layout is unchanged, but has received a few minor modifications. A drop-off has been added at the entrance to the tunnel in place of a downhill slope. The three-quarter turn into the glider ramp at the end has been modified into an anti-gravity section, complete with spin boost pillars, while the water puddles have been removed. The Koopa Clown Car air current found near the S-Bend has been moved to behind the banner, instead of beside it. The music is also roughly the same, similar to 3DS DK Jungle and  Wii Grumble Volcano, but an electric guitar has been added. Bowser's minions - Koopa Paratroopas, Dry Bones, Hammer Bros., Fire Bros., and Boomerang Bros. are spectators for this course. In addition, like in the rainy courses in Super Mario 3D World, rain drops flow down the screens of both the GamePad and the TV, just to add a minor effect.

Shortcuts

 * Like with the turn after the S-bend, it is now possible to use a Mushroom or Star to cut through the mud on the anti-gravity segment.

Staff ghost
The 150cc staff ghost for this course is Dry Bowser on the Bone Rattler, with a time of 2:09.513. In Mario Kart 8 Deluxe, the 200cc staff ghost is Bowser.

Mario Kart Tour
Neo Bowser City reappears in Mario Kart Tour, starting with the Tokyo Tour. Appearance-wise, it features elements taken from both its Mario Kart 7 and Mario Kart 8 versions, though it contains more cues from the former due to its lack of anti-gravity. The city now has more gray hues than blue, the screen near the starting line now shows four players racing, and the bridge is now a glass tunnel. The rain is only present if the game is not in battery saver mode. This course is a favorite of Bowser, Bowser Jr., Ice Bro, Funky Kong, Waluigi (Bus Driver), and Dry Bowser (Gold). It is also a favorite of Rosalina (Halloween) and Bowser Jr. (Pirate) if they are at level 3.
