Yes, unless if you know someone with a foreign game cartridge

There are two ways to get it that feel rewarding (once you get it): masuda method or random encounters. Out of the options, the masuda method is the best.
The Masuda Method is breeding a Pokemon of a different nationality with a Pokemon of your nationality (a Japanese Poké with an English Poké), increasing the odds of a Shiny by 75%
Yes, this does not ruin the Masuda method. The chances are the same when you exit out of the game and come back. Just do not remove any Pokemon from the Day-Care to continue the Masuda method.
The easiest way is to use codes
you got to the GTS and you get a japanise DITTO.and then you go to route 3 and go in the daycare put your japanise DITTO in the daycare with the pokemon you want shiny and then breed them there is a 2568 chance geting a shiny out of masuda method and there is a 8965 chance of running in to a shiny pokemon in the grass. hope this helped.
