Hōjō Masamura

was the seventh Shikken (regent) of the Kamakura Shogunate, regining from 1264 to 1268. He was the son of Hōjō Yoshitoki, the second Shikken, and brother of Hōjō Yasutoki and Hōjō Shigetoki.

Life Hōjō Masamura was born on July 10, 1205, the son of Shikken Hōjō Yoshitoki. His mother was the daughter of Iga Tomomitsu. Shikken Hōjō Yasutoki was his half brother. Masamura was born on the day Hatakeyama Shigetada was killed. Masamura held his genpuku, coming of age ceremony, in 1213.

Before his regency, he served as Captain of the Right Division of Bureau of Horses (uma no gon no kami), Governor of Mutsu Province, and Mayor of the Left Capital District (Sakyō no gon no daibu).

After the sudden death of Yoshitoki, Masamura's mother and his elder brother, steward of the Mandokoro Iga Mitsumune, conspired to replace shogun Kujō Yoritsune with his son-in-law, associate counselor Ichijō Sanemasa, as shogun, and to make Masamura the next shikken. The plan failed, but Masamura was pardoned by his half-brother Yasutoki and was not punished.

In 1239, Masamura became a member of the Council of the Shogunate (hyōjōshū). In 1249, he became the head of the newly established High Court of the Shogunate (hikitsuke).

In 1256, he was appointed rensho, and assisted the shikken Hōjō Tokiyori and Nagatoki.

In 1264, Nagatoki resigned due to illness, and Masamura became the seventh shikken. Hōjō Tokimune subsequently became his rensho.

During Masamura's reign, Prince Munetaka was removed from the post of shogun and Prince Koreyasu was appointed as the seventh shogun. Masamura and Tokimune are thought to have played a central role in this change of power.

In 1268, Masamura stepped down to the post of rensho, and gave the post of shikken to Tokimune, who had grown up. Tokimune, who reigned during the difficult time preceding the Mongol invasions of Japan in 1274 and 1281, is said to have been frequently aided by Masamura.

Masamura fell ill in 1273, and entered the priesthood, taking the Buddhist name Kakusū. He died shortly after on June 13, 1273.
