Are all cities in Japan designed the same?

Question:

I watch a bit of anime and iIve noticed (in anime's such as Gantz, Bleach, Highschool of the Dead and some others) the layout of the streets and stuff seem the same. There's always solid concrete walls around the house, then street thin enough to only fit maybe one car in, almost like and alley way. There also seems to be, like a river somewhere in the suburb but it doesn't seem natural because on either side, there's 2 grassy perfect slopes leading to it. Are msot suburbs in Japan liek this and if so what's the reason for the design?

Answer:

No. Sapporo, for example, is very different than Tokyo.
