For those of you wondering,
The title DOUBLE DRAGON is only partly based on the film title. After seeing the look, I noticed the Chinese symbol of Chi (气) or energy is seen in the back, creating Mt. Fuji. This symbol in Chinese coincides with the tale of two dragons that brought life and harmony, or energy to the world.
In modern day China, the Double Dragon coin is a sign of good luck and long life.
However, the Japanese version of the coins, as pictured above, stands for bringing those separated together once again, in their hearts or in person. It is a promise that you will see someone again.
The Japanese tale of the double dragons ends with the two dragons becoming separated, but they are not sad because they are UNDER THE SAME SKY.
