You have to see Raikou in the basement of Burned Tower and then use your Pokégear's Map in order to track its location however it'll change its location on the map to a random Johto location when you go to another location.
You cannot catch Raikou in Pokemon Black. You have to transfer it from Diamond, Pearl, Platinum, Heartgold, or Soulsilver.

Pokemon HeartGold and SoulSilver.
After you beat the elite 4 again raikou starts roaming again.
You cannot catch Raikou in Pokemon Diamond and Pearl. To get Raikou in Pokemon Diamond and Pearl, you must trade for one from Pokemon HeartGold and SoulSilver where it can be caught or transferring from Pokemon FireRed and LeafGreen.
