Route 254 runs from Bunkyō Ward, Tōkyō, to Matsumoto City, Nagano Prefecture, via Toshima, Itabashi, and Nerima Wards in Tōkyō, Wakō, Asaka, Niiza, Fujimi, and Kawagoe Cities in Saitama Prefecture, Fujioka, Takasaki, and Tomioka in Gunma Prefecture, and Saku and Ueda Cities in
Nagano Prefecture.

The road conditions are varied, ranging from a main street in the center of Tokyo to a narrow road through mountainous areas and a 2,500-meter-long tunnel through Mount Misa in Nagano Prefecture.
The Misayama Tunnel Toll Road and the Matsumoto Tunnel Toll Road, which were toll-free for a long time, became free of charge in September 2020.

This video was recorded along routes that run as far as possible on bypasses that have already been opened, including those that are partially in service.
