Hojo Tokimune (?? ??, 5 June 1251 – 20 April 1284) of the Hojo clan was the eighth shikken (officially regent of the shogun, but de facto ruler of Japan) of the Kamakura shogunate (reigned 1268–84), known for leading the Japanese forces against the invasion of the Mongols and for spreading Zen Buddhism.
Tokimune was known to rule with an iron fist, and also eventually monopolized at one point all three titles of power, namely holding offices of tokuso (head of clan, since birth), and rensho (Vice Regent).
During his lifetime, the following seats of power: Japanese Emperor, Imperial Regent (sessho), and Imperial Chief Advisor kampaku, and the shogun, all had been completely marginalized by the Hojo Regents.
