In order to get into the Sinjoh Ruins, you have to have Arceus first in your party, and walk into the ruins research center. I believe you must also have the National dex.
EDIT: You do not have to have the national dex.
take arceus to the unown ruins
Shinto Ruins is only obtainable if you have an Arceus.
Its shinjo ruins and you need to bring only arceus to the ruins of alph and you will find cinthia and she will bring you there
Once you have Arceus, go to the Ruins Of Alph and you'll be able to go to Shinto Ruins.
well is´NT exactly a region, the Shinto ruins are localized in Sinnoh, and for unlock it you need to show an event Arceus to the old man inside the house of the Ruins of Alph, then the guy will lead you inseide the unown ruins and you will be transported to the Shinto Ruins.
In the English version, it's Sinjoh ruins. You have to have an arceus from the event and trade it over from DP.
you need to finish the puzzles!
its not in the johto or kanto region. bring arceus to the unknown ruins. then a guy will alow you to go to the ruins where u get a LV1 giratina dialga or palkia with repective orbs
He goes to the Shinto Ruins in Pokemon HeartGold and SoulSilver. You will see him if you do the Arceus subquest
First you need the special event Arceus you need the national dex and you have to have beaten the elite four. Go to the alpha ruins, go to the cave, something just happens. (ps. make sure you got Arceus in your party.)
Yes! First get an arceus. Then go to ruins of alph. Cynthia will be there and then you go to Shinto ruins. Then you can catch one of the 3 legends: Giratina palkia dialga.
First, you need an Event Arceus and you go to Shinto Ruins. Cynthia will be there as well. Then Arceus can create either Giratina, Dialga or Palkia. They will be at Level 1.
