When were the first London double-decker buses introduced?
Double-decker bus
In 1979, Chuo Kotsu, a chartered bus operator in Osaka, imported the Neoplan Skyliner.  Skyliner, and the other imported buses: Van Hool Astromega TD824, Drögmöller E440 Meteor, and a few MAN coaches inspired Japanese bus manufactures, who developed three domestic models in the mid-1980s: "Nissan Diesel Space Dream", "Hino Grand View" and "Mitsubishi Fuso Aero King".  They did not, however, sell very well as the ceiling was only 1.7 metres (5ft 7in) high.  Nevertheless, Aero King was sold for 22 years, but, being unable to meet exhaust gas emission and safety levels, production stopped in 2005.
