after you beat the elite four and the champion you visit professor Elm's lab and talk to him then he gives you the ticket to get on the boat at Olivine city
In Pokemon HeartGold, the player can travel between the Johto and Kanto regions on the SS Aqua 2. In order to get the boat to stop, the player must rest in their cabin.
You have to get that old persons granddaughter then it will say that the S.S. Aqua has gone into Kanto.
Do you have any unfinished business in Kanto? or in Johto?
In Kanto. It will be where you get dropped off on the SS Aqua.
Actually you can face off against Both Kanto and Johto Gyms again once you've defeated Red ask for their Phone Numbers in the areas you find them, notice they won't be in their Gyms they will be somewhere in either Kanto or Johto Kanto gym leaders can be found somewhere in Kanto while Johto Gym leaders can be found in Johto Areas you can only battle them on certain days not at the same time and you go to Saffron city in Kanto and the fighting Dome for rematches.
She is a Sinnoh gym leader, the game is based off the regions of Johto and Kanto.
you chase it throughout Johto and kanto and eventually you will find it where you found misty before you battled her north off cerualean city
Take the Magnet Train in Goldenrod City or S.S. Aqua. To use S.S. Aqua you must get a ticket off Prof. Elm, which he'll give you when you talk to him and you've beaten the Elite Four. When you fix the nuclear plant and get a ticket, you can also use the Magnet Train.
Yes you have to get all 16 badges (Johto and Kanto) then go east off Cerulean and to the power plant then you'll see him, press A next to him and he'll be at level 50. Hope you caught Snorlax!
Yes, there are. Just as Pokémon Gold & Silver Versions did, HeartGold & SoulSilver have Trainers start out in the Johto region. After winning the eight badges and defeating the Elite Four, Trainers can then travel through the Kanto region as well. http://bulbapedia.bulbagarden.net/wiki/Pokémon_HeartGold_and_SoulSilver_Versions
Kanto is the map where you first start off not the island 1,2,3,4...
You beat the Indigo Plateau and take the S.S. Aqua over to Kanto, get off at Vermillion City, Walk North through Saffron City, and the town above that is Cerulean City and on the Northern border is Nugget Bridge.
