Today the flag of Japan flies in celebration of the nation’s flag day.

Japan’s flag was informally adopted on August 5, 1854. It was officially adopted on August 13, 1999. The flag represents the ball of the sun, though it’s often referred to as the “ rising sun.”

Also flying is the flag of Greenland, which is also red and white and also includes a representation of the sun. The white half of the flag symbolizes the icecap, icebergs and ice floes, while the red half symbolizes the rising and setting sun, which gives the sea its beautiful red sheen.
