Will it be possible to transfer from JP to NA/EU servers when transfers go live?

I really just want to play and it is a fact that the JP and EU servers have open space right now. I know that server transfers are going live in the near future, but the announcement fails to mention is JP to NA servers ect will be possible. I have searched the forums and was unable to find an answer on this topic. If anyone out there can answer this or point me to a forum article or link that addresses this thank you in advance.
