my name is hana, I was born in Kyushu and had lived there till 16 years old. the places you're planning is enough I think.
I've heard many oral traditions about the Christians. I wrote a book about it. If you are interested in it, I'd like to send it to you of course free, I'm not a professional.
It's in paperback and Kindle book.
