Hōjō Ujinori

Who They Were

Hōjō Ujinori (北条氏規, ほうじょう うじのり) was a samurai of the Sengoku period, the long era of civil war that ran from the mid-fifteenth century until the reunification of Japan at the end of the sixteenth. He was the fourth son of Hōjō Ujiyasu, the daimyo — 大名, だいみょう, a regional warlord who held territory and commanded armies in his own right — who built the Hōjō domain into the dominant power of the Kantō region, the plain surrounding modern Tokyo.

Ujinori was born in 1545, in the fourteenth year of the Tenbun era (天文, てんぶん). His mother was Zuikei-in. His life spanned almost exactly the second half of the sixteenth century, the decades in which three successive warlords — Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa Ieyasu — dismantled the independent domains and forced every samurai family in Japan to choose between submission and destruction.

Life and Career

Ujinori's career was shaped by an accident of childhood. Very early in his life he became an acquaintance of Tokugawa Ieyasu, the future founder of the Tokugawa shogunate, because both boys were at the time hostages of the Imagawa, a neighbouring clan that held them as guarantees of their fathers' good behaviour. That shared captivity created a personal relationship that would later save Ujinori's life and give him a second career.

For most of his adult life he served the Hōjō cause as a commander and administrator within the family's Kantō territories. The end came in 1590, when Toyotomi Hideyoshi, having effectively unified Japan, turned his enormous army against the Hōjō. The campaign centred on Odawara Castle, the Hōjō stronghold, which Hideyoshi invested with a force vastly larger than anything the Hōjō could field.

Ujinori was persuaded to surrender while Odawara Castle was under attack. He then set off to Odawara in an attempt to negotiate peace — a mission that placed him between a besieging army and his own besieged family. The Hōjō domain was extinguished, but Ujinori was not. Tokugawa Ieyasu granted him the Sayama fiefdom, an estate assessed at ten thousand koku. The koku — 石, こく — was the standard unit of rice, roughly the amount one person would eat in a year, and it was how samurai wealth and status were measured; ten thousand koku made Ujinori a daimyo in his own right, though a small one.

He held Sayama until his death on 22 March 1600.

Why They Matter

Ujinori matters for two reasons, one structural and one personal.

Structurally, his fate illustrates exactly how the Sengoku period ended. The Hōjō were one of the last great independent houses, and 1590 was the year Hideyoshi broke them. Ujinori's surrender and his subsequent reward by Ieyasu show the mechanism by which the victors absorbed the defeated: not extermination, but reassignment. A Hōjō prince became a Tokugawa vassal with a modest but real domain. The same pattern repeated across Japan in these years, and it is why so many samurai families of the Edo period traced their standing to a surrender rather than a victory.

Personally, Ujinori's relationship with Ieyasu is a rare documented case of a hostage friendship that outlived the hostage system. Boys held as pledges by the Imagawa were not expected to meet again as free men on opposite sides of a war. That Ujinori did, and that Ieyasu chose to give him land rather than destroy him, says something concrete about how personal ties functioned inside the brutal politics of the period.

The Name in Japanese

The name is written 北条氏規, read in kana as ほうじょう うじのり, and romanised as Hōjō Ujinori. The long vowel in Hōjō is written with a macron; the family name is sometimes seen as Hojo in English text that omits it.

Broken down character by character:

• 北 — read ほう (hō) in this name. The character means "north". It is a common element in Japanese place names and surnames.
• 条 — read じょう (jō) in this name. It means "article", "clause", "line" or "strip". Together, 北条 originally referred to a northward-running strip of land, and it became the name of one of the most powerful warrior houses in Japanese history — though note that the Hōjō of Ujinori's day are the later Hōjō, a different family from the Hōjō regents who ruled in the thirteenth century. The later Hōjō are also called the Odawara Hōjō after their castle town.
• 氏 — read うじ (uji) in this name. It means "clan", "family" or "lineage", and it is the same word used for the pre-modern kinship groups that structured early Japanese society. In the Hōjō family, this character was inherited from generation to generation as a fixed element in male names.
• 規 — read のり (nori) in this name. It means "standard", "rule", "measure" or "norm". As a name element it carries the sense of a model or a principle.

The structure is typical of samurai naming. The first character of the given name, 氏, is a hereditary element shared across the Hōjō line — Ujinori's father was Ujiyasu (氏康) and his son was Ujimori (氏盛). The second character, 規, is the individual element that distinguishes one brother from another. A reader who learns to spot 氏 in a Hōjō name can immediately place that person inside the family tree.

Legacy

Ujinori died on 22 March 1600, a few months before the Battle of Sekigahara decided who would rule Japan. His son, Hōjō Ujimori, continued the family line after his death. The legacy of the Hōjō clan passed through Ujimori rather than through any restoration of the old Hōjō domain, which had ceased to exist in 1590.

The line that Ujinori founded at Sayama was therefore a continuation in name and blood, not in power. His descendants were Tokugawa-era samurai of moderate rank, carrying a name that had once belonged to the masters of the Kantō. That is the shape of the transition from Sengoku to Edo: the great houses were broken, and their sons were reissued smaller domains and told to serve.
