Doing some checkups before a run, I've noticed that different amounts of "required money" are given in the intro depending on the country selected.

European countries - 60 000EUR British countries - 40 000GBP Japan (And USA) - 80 000USD

Cash for Hudson Tech race: Europen countries - 6000 + 1500EUR (8 runs required) British countries - 4000 + 1000GBP (8 runs required) Japan (And USA) - 8000 + 2000USD (8 runs required)

Soooo. I guess that the same amount is given everywhere, but with a slightly different multiplier.
