HISTORY OF THE RISING SUN FLAG

What is the Rising Sun Flag?
It is a flag that was adopted by Japan in the 1870s. It depicts a red circle surrounded by sixteen rays on a white background. 
Where did the Rising Sun Flag come from?
There are 2 theories: 
In 607 A.D., the Emperor of Japan sent a diplomatic envoy to Sui Dynasty China where he sent a letter addressed to the country addressed to the sovereign of the “land where the sun sets (sun-set country),” from the sovereign of the “land where the sun rises (sun-rise country),” referring to Japan’s geographic location relative to China.
It is meant to resemble a chrysanthemum, a symbol of the Emperor and the Imperial Family of Japan.
