The "Philadelphia Coastline", named as such in All-Star Battle despite the characters having long left Philadelphia and reached New Jersey, is the place where the climactic battle between Johnny Joestar, Gyro Zeppeli and Funny Valentine happens.
Before the events of Steel Ball Run, the place is an unremarkable patch of land bordering the Atlantic Ocean. A gentle slope covered in grass and a few trees scattered on it leads from the interior of the land to the coast. The only landmark in this place is the railroad which connects Philadelphia to New York.
The Philadelphia Coastline is greatly affected by Lucy Steel's Ticket to Ride and Saint's Corpse. Due to their power, the world itself is drawn to Lucy's position, and a bit of the land disappears. Moreover, the Ocean itself is drawn to Lucy and begins flooding a patch of land, although the water stops near Lucy and the dimensional wall created by D4C Love Train, creating an arena of a sort surrounded by small walls of water. Moreover, Tusk ACT4 leaves here a crater after pummelling Funny Valentine into the ground, the crater serving as a focal point into which Valentine is forcibly drawn due to the power of the Golden Spin.
- Stage Gimmick: D4C Love Train grants the combatant who touches its column of light a stock of Heart Heat Gauge, only recurring if the light fades before anyone touches it.
- Situation Finish: The loser is tossed into a sign warning travelers about bears.
