Toyota Century: The Toyota Century (Japanese: トヨタ・センチュリー) is a large four-door limousine produced mainly for the Japanese market, serving as Toyota's flagship car within Japan; whilst globally the unrelated Lexus LS series is Toyota's flagship luxury model outside Japan.  Production of the Century began in 1967 and the model received only minor changes until a redesign in 1997.  The Century derived its name from the 100th birthday of Sakichi Toyoda, the founder of Toyota Industries.  The Century was available with only a V8 engine, the third Japanese built sedan post-war, at its introduction in 1967 until a major redesign in 1997, and is now only available with a Toyota built V12, an engine unique to the Century.  Although the Century is a premium, full size luxury sedan, it is not available at Japanese Lexus dealerships; it can only be purchased at specifically identified "Toyota Store" locations.  The logo used throughout is called the "Hō-ō 鳳凰" or "Fushichō" from Asian mythology, representing the Imperial House of Japan.

The second generation was the first diesel engine at 1500cc used in the CS20 series 1959 Toyota Crown in October 1959.  Japanese market vehicles with diesel engines were exclusive to Toyota Japan dealerships called "Toyota Diesel Store" locations from 1979 until the dealership was cancelled in 1988.

Toyota Voltz: The Toyota Voltz was a five-door hatchback sold from August 2002 to the end of 2004.  It was assembled by NUMMI in Fremont, in the U.S. state of California and marketed by Toyota in its home market of Japan, but curtailed after a disappointing sales volume of just over 10,000 units.  The Voltz was produced alongside the Pontiac Vibe in Fremont by NUMMI (New United Motor Manufacturing, Inc), a joint venture between General Motors and Toyota.  This vehicle is known as the Pontiac Vibe (itself a version of the Toyota Matrix) in North America.  The Vibe was exported to the Japanese market (with minor badging changes and right-hand drive configuration) as the Toyota Voltz, and was exclusive to Toyota Japanese dealerships called "Toyota Netz Store."  Whereas its exterior styling is identical to the Vibe, some interior details differ, matching the interior of the Matrix instead.  Curiously, the North American Toyota-branded Matrix was not sold in Japan.

Toyota Carina ED: The Toyota Carina ED was a Japanese compact car created in 1985 as a companion to the 1984 Carina sedan.  It was positioned as the four-door Celica, with a similar focus on luxury found on larger Toyota hardtop sedans, like the Toyota Crown and the Toyota Cresta.  It was the counterpart of the Corona EXiV.  Its design sought to emulate the hardtop four-door coupé styling of large American and European sedans, resulting in a small, low cabin with longer front and rear ends.  The ED's B-pillar stood up in the middle with no purpose other than to hinge the rear door on; it was not attached to the roof side of the cabin.  The ED achieved huge sales in Japan, and other Japanese manufacturers introduced the Mazda Persona, Nissan Presea, and Mitsubishi Emeraude around the same time.  "ED" is the initials of "Exciting" and "Dressy".  When the Carina ED was discontinued, the Toyota Brevis appeared for the market segment served by the Carina ED.

Nissan President: The Nissan President (Japanese: 日産・プレジデント "Nissan Purejidento") was a Japanese luxury limousine produced by Nissan from 1965 to 2010.

Widely considered by the media to be one of Toyota's worst flops, the experiment provided the foundation for Toyota's Scion marque.  The endeavors of this approach were also used in the home market of Japan.  The Japanese market efforts were the result of several Japanese companies contributing products or services under the WiLL brandname, and Toyota's contribution was three vehicles offered at restructured Toyota Japanese sales channels from "Toyota Vista Store" to "Toyota Netz Store".
