Last time, we went to a factory of stone in Uruma. During our tour I saw this stones and it looks familiar to me. And one of my office mate ask the management where does this stones came from. He said it came from the Philippines. So that is the reason why this stones are very familiar to me. I told my companion that you can see many of this stones in the Philippines even in front of our house.
On the next photos you will see a stones like this and yes this photos are taken in front of our house in Philippines. You will see many stones just like on the first photo. There is also big size of this stones as you can see on the photos.
All in all I enjoyed our study about stones in Okinawa. =)
