Emperor Keikō
Per one of the legends in the Yamato Takeru cycle, Emperor Keikō sent him to the eastern provinces, whose "Kuni no miyatsuko" had rebelled against the imperial court. His enemies attempted to kill him by setting fire to a grassy plain, but he escaped by using the powers of his magical sword, the "Kusanagi no tsurugi" and two magic stones. The sword, one of the Imperial Regalia of Japan is kept at Atsuta Shrine in Nagoya, along with one of the magic stones. Yaizu Jinja claims to have the remaining stone, as well as to have been built on the location of Yamato Takeru’s miraculous escape.
