>if every city had to connect to every city.
It doesn't have to connect directly. It's more like how train lines work in the real world, with a train traveling between two termini and stopping and multiple local stations along the way. See how my network map above forms a connected graph? So Fukuoka in Kyushu isn't connected directly to Sapporo in Hokkaido (which would be pretty much impossible anyway), but you can still get to Sapporo from Fukuoka by traveling north to Kyoto, east to Tokyo, and then north again to Hokkaido. The caveat is that you have to stop at pretty much every station along the way, and you will have to change trains a few times.
