Japan Summoning

In the Great Orient, lies a continent called Rodenius. One day, an unidentified flying object arrived at Qua-Toyne Principality's airspace. That UFO defied the Principality's common sense, but it was just a harbinger of something even more shocking. Far to the eastern sea, a group of islands suddenly appeared. The country of the islands called itself: Japan. According to them, their nation had been transported to another world. Now finding themselves separated from their old world and must survive in the new one, how will Japan interact with the native countries of this world? Will they greet it as a friend or as an enemy?
