Digging up the family tree in Okinawa

My Dad's side of the family is in Okinawa. While we were there, we got in touch with some folks to figure out where his family came from. We stayed in Okinawa for 4 days,and had a good time there. We met some very nice people, ate some good food, and went to see some awesome places.
We met up with the Gishitomi family, and although their name is slightly different, the chinese characters that make up their name is the same as our family, and it is pretty rare.

We also caught up with Mr. Takara, that keeps track of families in the Oroku district in Naha, Okinawa. Him and his wife were able to help us track the Uehara side of my Dad's family.

We were able to visit the Uehara grave site, which looks like a giant retaining wall on the side of a mountain, but it is actually a gigantic tomb.

We were able to see Gishifu-jima, which is an island off the coast of Okinawa, and is probably named after one of my ancestors. That was pretty awesome =)

We were able to figure out some stuff about the family, but for more details on the Gishifu side, we would have had to gone to an island called Ishigaki. It was a little too much out of the way, plus it would have been more digging amongst old documents.
