Nitta Yoshisada
Emperor loyalist Nitta Yoshisada in 1333 invaded Kamakura, deposing its Regent Hōjō Takatoki and ending the 145-year old Kamakura shogunate. According to the legend, being unable to defeat Kamakura defenses on land, he went down to Shichirigahama and, at the impassable cape of Inamuragasaki, prayed to the god Ryūjin to withdraw the waves and let him through.
