What is the name of Toyota's flagship luxury sedan primarily sold in Japan?

Toyota’s flagship luxury sedan primarily sold in Japan is the Toyota Century.

The Century debuted in 1967 and was named to commemorate the 100th anniversary of Sakichi Toyoda, founder of the Toyota Group. Designed as a formal Japanese luxury car, it emphasized quietness, rear-seat comfort, craftsmanship, and dignified styling rather than sporting performance or mass-market appeal.

For decades, the Century served as a chauffeur-driven vehicle for business leaders, government officials, and other prominent passengers. Its restrained appearance and traditionally detailed cabin helped distinguish it from more globally oriented luxury models. Toyota sold the sedan mainly in Japan, where it occupied a special position above ordinary Toyota passenger cars.

The Lexus LS is Toyota’s international flagship luxury sedan and is often confused with the Century. The Avalon was a large mainstream sedan, while the Crown occupied an important but generally less exclusive position. Toyota later expanded the Century name into a larger SUV-style model, but the Century sedan remains the canonical answer to this question.
