Next to my apartment there is some kind of office, and behind it, a car park. The car park is full most of the time, given Japanese people tend to work ALL the time.
However, some mornings I see the cars arriving. You notice that they all just park each other in, so there must be some serious negotiation at the end of the day - who wants to go, and who is trying to impress by staying the latest... I seriously don't know why they don't just mark lines, and give each other some access!
In Japan it is really important to be seen to be busy - Japanese people often talk about how busy they are, while they are sitting in the staffroom drinking coffee. Or they do this funny run/walk - moving their feet quickly but not moving anywhere fast! And, all the staffrooms are packed full of 'work' (piles and piles of papers). So I suspect parking the car closest to the building is a sign of working the hardest.
