Anyway, enough about me, you came here for a flag didn't you? Of course you did, and I've got one for you. In this post we have the Flag of Japanese Siam.
It comes from a world where Japan avoided engaging America during World War II and never allied with Germany and Italy. Among other things, this version of World War II saw the collapse of the Soviet Union due to Germany not wasting troops in North Africa and lasting till spring, and ultimately end with the allied atomic bombing of Munich and Dresden.
Meanwhile, the Japanese managed to retain their colonial empire and got involved in a Cold War with the United States. Despite depicting itself as the a union of East Asian people's, in reality Japanese society is highly stratified; with pure blooded Japanese as the ruling class and all other ethnicities as second class citizens.
Recently, however, the younger generation is beginning to grow weary of their parents' society and are increasingly liberalizing. There have also been movement to grant more rights to non-Japanese citizens. At the same time, many in the international community are beginning to suspect that Japan has been less than honest about the atrocities that occurred in the building of their empire.
