Turbo Granny is a Japanese urban legend originating near Mount Rokko in Hyogo Prefecture. The story describes a supernatural elderly woman who appears in drivers’ rear-view mirrors at night, racing at unnatural speeds to overtake or scare them. Most sightings depict her as fleeting, but some versions portray her as malicious with her tailgating, banging on windows, or causing accidents.

Variants include:
* Malicious Granny: Chases or attacks drivers.
* Roadside Granny: Stands by highways, then lunges at cars.
* Ghost Car: Drives a spectral vehicle at high speeds.

The legend likely began as a cautionary tale against reckless nighttime driving. Symbolically, she may represent a spirit of someone killed in a car accident or an unexplained nocturnal phenomenon.

* The legend has influenced various works of fiction, including:
** Turbo Granny in Dandadan – A supernatural entity appearing in the manga series, inspired by the urban myth.
** Shin Megami Tensei V: Vengeance – Turbo Granny is a recruitable demon, staying true to her eerie highway-haunting origins.
** Dash Granny in Mob Psycho 100 - Dash Granny is a regular grandma that dashes through mountainside roads. Inspired by the urban myth.
