I knew I saw it somewhere..
Unfortunately it's not Japanese at all, but a Ford Europe project called "P-229".
It started 1983 as a non functional maquette which wasn't shown to public.
1986 it was lend from Ford Germany to Swiss "Verkehrshaus" in Lucerne which was the most frequented car museum in Switzerland that time. Till the early 1990s the P-229 was part of the exhibition "100 years of car history" labelled as "1:1 Fibreglass Model with Wheels, Colour in Red".
Originally the wind-tunnel proved mock-up was supposed to be a possible Ford Escort successor. It was designed under the aegis of Patrick LeQuement who was Ford's head of design back in 1983. In 1986 he was already working for VW few time before he finally moved to Renault.
