Tokyo Auto Salon is the world's largest custom car exhibition. Held every January at Makuhari Messe convention center, the show attracts over 300,000 visitors across three days. Every major Japanese tuner, aftermarket manufacturer, and automotive media outlet participates. For car enthusiasts, this is the pilgrimage.

The show began in 1983 as the Tokyo Exciting Car Show. Originally focused on aftermarket parts and modified vehicles, it has evolved into a comprehensive automotive event where manufacturers also debut concept cars and special editions. The scale has grown exponentially while maintaining its grassroots spirit. From enthusiast gathering to global phenomenon.

Every major tuner brings their showcase builds. Top Secret, Liberty Walk, RWB, HKS, Blitz, Varis, and dozens more—companies spend the entire year preparing vehicles specifically for Auto Salon debuts. These demo cars represent the pinnacle of Japanese aftermarket engineering and styling. The builds here set industry trends.

OEM manufacturers now participate extensively. Toyota Gazoo Racing, Nissan NISMO, Honda Type R, Subaru STI—official performance divisions debut new products alongside aftermarket companies. The line between factory and tuner continues to blur. Even manufacturers acknowledge tuner culture's influence.
