The Fujicabin Model 5A was a microcar built in Japan in 1955.

The Model 5A was a cabin-style three-wheeler that utilised the epoch-making FRP for full monocoque construction designed by Tomiya, who also designed the Flying Feather.

It was equipped with an aircooled, two-stroke, one-cylinder engine. The body weighed only 130kg and it could attain the high speed of 60km/h.

Its aerodynamic body design and other features were revolutionary, but the FRP technology could not keep pace and only 85 cars were produced.
