Find the number n such that the following alphanumeric equation:

   KYOTO
   KYOTO
 + KYOTO
   TOKYO

has a solution in the base-n number system.

(Each letter in the equation denotes a digit in this system, and different letters denote different digits)

That's all great and such, but I think all the Ts are supposed to equal the same amount. :)

It's not based on base 5 or 10, as you will see in the numerous full solutions below ;)
