It was Meiji 37 or year 1904 (somewhere in the timeline of Sakura Taisen), when The Great Empire of Japan started to increase its national power quickly by the westernization during the Meiji era. On the other part of the world, Czar Russia was going to extend its hegemony to the East and hence started a war against Japan. The war is known as Russo-Japanese war right now. Japanese army with quick series of victories over Russia astounded the world. The war culminated with the fall of Russia’s Port Arthur (Lushun in China) to the hand of Japanese army.
