The Fuji Cabin, designed by “the Leonardo da Vinci of Japan”, Ryuichi Tomiya, made its appearance at the 1955 Tokyo Motor Show. It was a beautifully streamlined two-seater coupe on three wheels, and it was powered by a Gasuden scooter motor with kick start. It was a monocoque design, strengthened by a full-length tunnel bringing cooling air to the motor. There were two rounded beetle-wing lids providing access to the motor and allowing warm air to exit.
The steering is by a closely-placed set of handlebars. The small but well-engineered motor incorporates a reverse gear, unusual for the typical Western scooter-powered microcar. There is a feeling of solidity to the entire structure, which is helped by the coat of dense insulation material sprayed inside the cabin roof, dashboard, and sides. The front wheels are independently sprung on rubber, and the rear is on a swing arm with a coil strut, providing a comfortable ride. A single Cyclops headlamp graces the shapely nose.
