Uzaylıların feodal Tokyo'yu istila ettiği ve ele geçirdiği bir çağda, işsiz bir samuray istediği gibi iş bulur.

Commanding shoguns and samurai warriors, exotic geisha and exquisite artisans—all were part of the Japanese “renaissance”; a period between the 16th and 19th Centuries when Japan went from chaos and violence to a land of ritual refinement and peace. But stability came at a price: for nearly 250 years, Japan was a land closed to the Western world, ruled by the Shogun under his absolute power and control. Japan: Memoirs of a Secret Empire brings to life the unknown story of a mysterious empire, its relationship with the West, and the forging of a nation that would emerge as one of the most important countries in the world.
