The Nissan Fuga (Japanese: 日産・フーガ "Nissan Fūga") is a full-size luxury sedan produced by Japanese automaker Nissan since October 2004.
 It is built on a wider, stretched wheelbase version of the Nissan FM platform.
 After the Nissan Cima and Nissan President were discontinued in August 2010, the Fuga became Nissan's flagship vehicle.
 In North America and Europe, the Fuga is sold as the second and third-generation Infiniti M (Q70 from 2014), where it has been the flagship of the Infiniti luxury division of Nissan since 2006.
The Nissan IDx is a concept car introduced at the 2013 Tokyo Motor Show by Nissan.
 It is supposedly inspired by the Datsun 510.
 The IDx is Nissan's answer to the "RWD tuner craze" that is ongoing and a direct competitor to the Hyundai Genesis coupe & Scion FRS/Subaru BRZ.
 The IDx is aimed at young buyers and racing gamers alike.
 A few quirks the car has that might not make production are the "side view mirrors" that are designed to be cameras rather than traditional mirrors as well as the side-exit exhaust.
 There is a possibility that Nissan is building more IDx concepts because there is a number (003 and 004) instead of a 001 and 002 on each of the concepts.
 With Nissan's looming decision to discontinue several current models such as the Quest, Xterra, Cube and possibly the Juke there is expected room in Nissan's lineup for a new entry-level sports car.
NAPS stands for Nissan Anti Pollution System a moniker used in Japan to identify vehicles built with emission control technology.
 The technology was installed so that their vehicles would be in compliance with Japanese Government emission regulations passed in 1968.
 The term was first introduced in Japan, with an externally mounted badge on the trunk of vehicles equipped.
 Nissan's implementation began with the Y44E V8 engine installed in the Nissan President along with all vehicles installed with the Nissan L engine and the Nissan A engine in 1975.
 The initial introduction of Nissan's technology was the installation of an exhaust gas recirculation valve, followed with the addition of a catalytic converter and an air pump that added oxygen into the exhaust to promote higher temperatures in the catalytic converter, thus cleaning the exhaust further.
The Prince Homer was a small commercial vehicle manufactured by the now integrated Prince Motor Company.
 It was available as a van, called the Homy, a double cab, or regular cab truck.
 The first model was known as the T64, and was sold as the Prince Homer or PMC T64.
 The T640 was introduced in 1966 and was sold as a Nissan (without any modifications aside from badging) due to Prince merging with Nissan.
 It was shared with the Nissan Cabstar which was sold at "Nissan Bluebird Store" Japanese dealerships.
 Production of the T640 ended in 1968.
 The Homer was exclusive to Japanese Nissan dealerships called "Nissan Prince Store", when Prince was merged with Nissan in 1966.
 The Homer name was discontinued in 1982, while the Cabstar name remained when Nissan refocused "Nissan Prince Store" vehicles as private purchase products.

 Early generations were based on the automaker's Japanese-market flagship sedan, the Nissan President, while models produced after 1996 were based on the slightly smaller Nissan Cima.
 Exports of the Q45 ceased after 2006, but the Cima continued to be sold in Japan until August 2010, when production of both the Cima and President ended.

The Nissan S130 is a sports coupé produced by Nissan in Japan from 1978 to 1983.
 It was sold as the Datsun 280ZX, Nissan Fairlady Z and Nissan Fairlady 280Z, depending on the market.
 In Japan, it was exclusive to Nissan Bluebird Store locations.
 It was the second generation Z-car, replacing the Nissan S30 in late 1978.
 The 280ZX was the first time the "by Nissan" subscript was badged alongside the Datsun logo, along with Nissan trucks.
 The 280ZX was "Motor Trend's" import car of the year for 1979.
 The 280ZX was replaced by the Nissan 300ZX in 1984.
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 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.
 The car was mainly used by corporate executives and government officials.
 It was a luxury sedan specifically aimed to the Japanese market, where its main competitor was the Toyota Century.
 The President was the flagship limousine, and was sold at Nissan Motor Store dealerships.
 During the 1970s, it briefly saw other Japanese competitors introduce large sedans called the Isuzu Statesman de Ville and the Mazda Roadpacer (derived from General Motors-Australia products) which were short-lived.

Answer: Imperial House of Japan
