Ryukoji Temple is a temple of the “Nichiren sect” founded in 1337. Nichiren offered plans to Kamakura shogunate for saving the nation in a time of crisis, however, the government did not listen but arrested him. Nichren was taken to Tatsunokuchi (place of execution). When it was about time to be beheaded, suddenly, a beam of light came into the place of execution and the executioner was dazzled by the intense light. The shogunate scared to death of this miracle and canceled the execution. The temple was founded on the remains of the Tatsunokuchi.
