The main specialization of the plant in those days was aircraft construction. After World War II, the company retrained and began supplying the market with high-quality Fuji Rabbit scooters with a 135 cm3 engine.
In fact, the very name of the Subaru brand, in Japanese meaning a star cluster in the constellation Taurus, was coined by one of the first plant managers, Kenji Kita. It was on the initiative of this entrepreneur that the company first began producing cars.
Even later, the plant began assembling motors for small agricultural machinery. The engine for the Subaru walk-behind tractor of any series is always popular among farmers and homestead owners today. Equipment equipped with motors from this manufacturer is characterized by simply excellent performance, reliability and ease of use.
