Legend has it that the word immortality, 不死 (fushi), became the name of the mountain, Mount Fuji. It is also said that the kanji for the mountain, 富士山 (literally mountain abounding with warriors), are derived from the Emperor's army ascending the slopes to carry out his order. It is said that the smoke from the burning still rises to this day. (In the past, Mount Fuji was a much more active volcano and therefore produced more smoke.)
