On our street, there are two homes with 7 cars each.  At both homes, only 1 car can fit in the garage because the rest is used for storage.  Two cars can fit in the driveways.  What that means is 8 cars all together are out on the street.  And, in our neighborhood, the houses were built such that not every home has a space in front of it.  Our home has a space on one side but not the other.  Still, people park in the "non" space which is only about 5 feet wide, meaning the car sticks into our driveway a good 3 feet or so.  All the fire hydrants on our street are blocked.  Another house has 4 cars but only 2 drivers.  The other 2 cars are "hobby" cars.  None of the cars are in the garage.  We have 4 cars as well, but 2 are in the garage, and the other 2 are in the driveway, so we do not take any street parking.  We need the Japanese law where you cannot purchase a car unless you can prove you have a space to keep it; otherwise, use public transportation.
