I don't really know what to say. It's very different out there in Turkey. It's Islamic country and very different culture. I'm sure your little boy will adapt a new life style better that you do as he's only 5. I don't really know any Japanese who live in Turkey. Turkey hasn't been accepted as a member of EU due to human rights issues etc. Where is he from in Turkey? If I were you, I wouldn't move there. Don't get me wrong. I love Turkish food and I'm recentlly getting into Turkish/German films but liveing out there will be a completely different story. Good luck.
