Is this a Japanese sea ?

Today it was really warm and a beautiful day in Shirahama !

The air was very clear and we could see Amagi mountains and Izu Oshima island.

Besides the color of sea was just emerald green.

When I was taking pictures in the beach, some poeple came there and said.....

" Is this a Japanese sea ?"

" We have never seen a beautiful sea like this except Okinawa !"

They were very surprised at this beach.

I always come and see this beach, and am surprised very much every time too.
