I've decided to collect various numbers and figures. I'll approximate distances with Google Maps highway distances, and I'll use metropolitan-area population figures.
France, UK, Belgium, Holland
Paris: 11.8m
P - London: 12.3m, 456 km, P - Brussels: 1.83m, 306 km, B - Amsterdam: 2.16m, 203 km
P - Strasbourg: 0.64m, 487 km
P - Lyon: 1.76m, 466 km, L - Marseille: 1.60m 315 km
P - Le Mans: 0.15m, 208 km, P - Tours: 0.14m, 239 km
Spain
Madrid: 5.84m
M - Barcelona: 5m, 618 km
M - Valencia: 1.71m, 355 km
M - Sevilla: 1.51m, 532 km
M - Valladolid: 0.32m, 211 km
Italy
Turin: 0.91m, T - Milan: 1.32m, 142 km, M - Florence: 0.37m, 317 km, F - Rome: 2.75m, 284 km, R - Naples: 0.96m, 229 km
Russia
Moscow: 10.1m, M - St. Petersburg 4.57m: 707 km
Japan
Aomori: 0.30m, A - Sendai: 1.03m, 362 km, S - Tokyo: 35.7m, 365 km, T - Osaka: 2.67m, 512 km, O - F*k*oka: 1.46m, 611 km, F - Kagoshima: 0.61m, 282 km
South Korea
Seoul: 24.5m, S - Pusan: 3.57m, 436 km
Taiwan
Taipei: 6.78m, T - Kaohsiung: 2.77m, 356 km
Germany and China are rather patchwork and confusing.
I've mentioned the larger cities on the routes; they range from a few hundred thousand people to a few million, with some much-more populous cities and a few much-less-populous ones: Le Mans and Tours. Route lengths are usually around 300 - 500 km / 200 - 300 mi, with a few longer ones here and there.
