The WWII plot to dye Mt. Fuji black

IN THE WANING MONTHS OF World War II, as the likelihood of a land invasion of the Japanese home islands loomed, the United States’ Joint Intelligence Center, Pacific Ocean Areas (JICPOA) instituted a new psychological warfare unit under the command of Colonel Dana Johnston.

Johnston to JICPOA’s commanding officer, General Joseph Twitty, the proposed operation would “give Fujiyama with some color other than that seasonably endowed by nature.”

In other words, the plan called for the marshaling of considerable manpower and equipment to dye Mt. Fuji black.
