What is the Toyota name for Lexus LS 400?

The Toyota name for the Lexus LS 400 is Toyota Celsior in Japan; globally, the same car was marketed as the Lexus LS 400. This naming split reflects how Toyota styled its domestic market differently from international markets, where the Lexus luxury brand was used.


Market naming differences


To understand how the LS 400 was named around the world, note the distinct domestic badge in Japan versus the Lexus branding used elsewhere.



  • Japan: Toyota Celsior — the LS 400 sold in Japan under the Toyota badge.

  • North America, Europe, and most other markets: Lexus LS 400 — sold under the Lexus luxury-brand umbrella.


Both names refer to the same flagship model, with the domestic Japanese version adopting the Celsior designation while international markets used the Lexus LS 400 branding.


Historical context


Origins of the Celsior name


As Toyota introduced Lexus as its global luxury brand, it designated the domestic Japanese version of the LS 400 as the Toyota Celsior. The Celsior name was used specifically for the Japanese market, while buyers outside Japan encountered the Lexus LS 400. This approach reflected branding strategies that differentiated domestic products from international luxury offerings.


Brand strategy and impact


The naming divergence illustrates how Toyota navigated regional branding: the Lexus brand carried luxury perception abroad, while the Celsior name resonated with Japanese buyers as a distinct Toyota product line. The outcome was a single generation of a vehicle known worldwide as the LS 400, but with two names depending on market or badge.


Summary


In short, the Lexus LS 400’s Toyota name in Japan is Celsior; in other markets, the same vehicle appeared as the Lexus LS 400. The difference showcases Toyota’s market-specific branding approach during the early years of its luxury-labeled lineup.
