Why can't I Poke-Transport Japanese events?

Question

I have a Shiny Rayquaza from Japan, and my brother has a Japanese event. Why won't Poke Transporter send them to my Y or his X?

Answer 1

Because they are hacked. According to this : http://www.gamefaqs.com/boards/696959-pokemon-x/68395519 you can transport Japanese to English pokebank.

Answer 2

Because there might be a chance they were hacked cause I tryed to import my japanese shiny genesect and it would let me till I saw where it was caught I have personally tested some Shiny Legends (Japanese) then I looked at where they were caught when they wouldn't transfer then I realized they were hacked so only Hacked Pokemon wont Transfer
