Will a Japanese event Arceus work on an English game?

[Callie]

My friend went to Japan and got me an Arceus when the event was happening there. If I put that Arceus into my Heartgold will I still get the level 1 Dialga/Palkia/Giratina?

Yes. It activates it on any region game with any regional Arceus. Jason made a topic exactly like this.

Woops, didn't see that. Thank you though.
