I thought Japan rounded up all the Muslims and deported them a few years ago?
They need to do additional cleanup
My understanding is they let a few Muslims in but not many. They officially pretend to not dislike importing Islam...but they dislike importing Islam for the obvious reasons-—that is the reasons that are obvious to everyone but the delusional left...but are trying to be quiet about it and not make waves. However there are people with certain skills and status that they will let in of any background so they have a few. When challenged on their policy of not letting in Muslims, they point to those few.
