武佐

The Legend of Musa: Spare Parts Warrior

Preserving Japanese Classic Cars from the Golden Era (1960s – 1990s)

What does 武佐 (Musa) mean?

In Japanese kanji, 武 (Mu) signifies martial warrior power and automotive performance, while 佐 (Sa) signifies assistance, support, and essential supply. Joined together, 武佐 (Musa) stands for the "Spare Parts Warrior".

Just as samurai relied on dedicated master armorers to forge and keep their battle gear sharp, classic Japanese sports cars—the iconic Fairlady Zs, Skylines, RX-7s, AE86s, and NSXs—rely on the Spare Parts Warrior to supply authentic components and keep them roaring on roads around the globe.
