Hihiirokane

Mythological · Legendary · Modern

A metal named in the Takeuchi documents, papers Takeuchi Kyōmaro presented in 1935 as his family's ancient records; they are a 20th-century forgery, and the metal appears nowhere in the Kojiki or the Nihon Shoki. As those papers and the occult writers after them tell it, hihiirokane is red like the sun or simply shining, cold to the touch, harder than diamond and proof against rust, and it carries heat so well that a handful of leaves will boil water. They claim the Three Sacred Treasures were made of it.

Lore & Narrative

The historian Kanō Kōkichi examined the documents in 1935 and published his proof that they were modern forgeries in June 1936. The metal outlived the exposure in occult magazines: in 1985 Asahara Shōkō, later the founder of Aum Shinrikyō, claimed in print to have found it.
