Owning a car is never cheap: It entails a variety of expenses, from parking fees to insurance to road maintenance taxes.

Because of this, car-sharing is now becoming a favored approach for a rapidly growing number of people as they try to pinch pennies and feel less inclined to drive everywhere.

A 33-year-old working mother became a registered member with a car-sharing station run by Time24 Co. near her home in Koto Ward, Tokyo, last spring. She rents a car whenever she takes her 2-year-old daughter to and from a day care center.
