The Japanese automotive market has matured, with sales hovering at about 4 million cars in the last decade. It is set to decline further due to the declining population, the ageing population that has given up driving a car, the younger generation that is not interested in owning a car. Against the declining sales trends, the car sharing market has grown both in market size and with regard to awareness, especially in mega cities like Tokyo since 2010. It is currently dominated by a few top operators in Japan and by the traditional car sharing business.
