Hihīrokane, described in the apocryphal Takenouchi Document, an alleged ancient writing in a lost script which details Japan's early history, Hihīrokane was used in the time of Emperor Jimmu, Japan's first emperor. The Kusanagi-no-tsurugi and the other Imperial Regalia of Japan are supposedly made from it. Its weight is lighter than gold, but harder than diamond. It was even said to be able to bring water to a boil without heat, violating the Law of Conservation of Energy. (Japanese mythology)
