You can't. Sorry! ;)
Pokemon Pear [and Diamond] is located in the Sinnoh region. You will not be able to get to the Johto region unfortunately. Sorry.
You can't get to Johto region in Pokemon Diamond/ Pearl, but you start there in Heartgold/ Soulsilver.
you go there after you beat the champion on diamond.
I don't think you can.
it is not possable
It has to be traded from Diamond, Pearl, or Platinum. There are no Buneary in the Johto region.
Johto region!
no, in Pearl as well as Diamond and Platinum, you can only be in the Sinnoh region
To get Ho-oh in diamond, you have to have a Johto region game, trade Ho-oh to Ruby, Saphire, Emerald, Leafgreen or Firered and then migrate.
You can't unless cheat or trade.mISDREAVUS IS ONLY IN POKEOMN PEARL.i CAN GET YOU ONE THOUGH.
Mainly Johto, but after you beat the Pokemon League you can go to the Kanto.
No. Johto is not an available region in Pokemon FireRed. You can only explore the region of Kanto and the nine islands surrounding it. Currently, only Pokemon Gold, Silver and Crystal are games which explore Johto.
