Did the so-called “Nanking Massacre” and the military comfort women forcefully taken by the Japanese troops actually exist as historical facts? In this book, we attempt to investigate whether the two events actually took place by using a new method. This is not merely to restore the international honor of Japan. We are hoping to review the causes of World War II, look over the world justice made by the victorious nations after the war and reveal the true world history. Searching for the Truth using spiritual method First chapter of the book is a spiritual interview conducted with the guardian spirit of Yoshikazu Sakamoto (1927 - Present), professor emeritus at the University of Tokyo, who also became Japan’s representative of the left wing scholar as a theoretical supporter on masochistic view of history. A guardian spirit is a part of the subconscious of the person living on earth and they are basically unable to lie. The second chapter is a “time travel” reading that goes back more than 70 years into the past, conducted by the spirit of Edgar Cayce (1877 - 1945), a psychic who was known as “The Sleeping Prophet” in the United States. The readings conducted by Edgar Cayce provides the details that would bring no doubts of Nanking city at the time when the large massacre is said to have taken place, the situation of the women who are said to have been military comfort women and the truth behind the anti-Japan propaganda of the United States during and after the war.
