Japan is an excellent place for visiting but not for living unless you luckily find a proper employer (might be yourself), which is also true to rental car. It's adventurous urban camping if you are a visitor. Most of the cities in Japan are enough safe for adults to walk outside even at midnight, and there are konbinis for clothing and food. So going to a gym (for shower) + renting a car (for sleep) can be more reasonable than staying at a hotel, and maybe you will have a priceless experience when figuring out how to survive in a center of the city. In reality, on the other hand, as this article says, the shared-car is a built-in system among the working poor. Laborers in Japan work too long, and their commute takes too long so the car is a savior to maximize their sleep time.
