The image is a photograph of a sign posted on a pole in a public space. The sign is in Japanese and translates to "Software Freedom Day" in English. The background of the sign is a light blue color with a map of the world in the center. The map is made up of different colors and shapes, representing different countries and continents. 

On the top left corner, there is a yellow sun with a green outline, representing the sun. Below the sun, there are two lines of text in Japanese that translate to "Do you know?" The text is written in both English and Japanese.

The sign appears to be promoting a software freedom day event, as indicated by the text on the right side of the image. The date "2015/09/19" is also written in the bottom right corner.
