When you come to Japan, one thing you notice is shapes. Shapes are different here.
Take the rectangle, for example. Most people would say that a parking space for a car is rectangular. Not always so in Japan. Holes are fair game as parking spaces in Japan, as well as swatches of garden and precipices.
Sometimes, land is just too expensive for houses to have a garage. Thus, cars are parked in any available space, even if the space in no way resembles the shape of the car.
