Ohatsu

Who They Were

Ohatsu (お初) was a daughter of Oichi (お市) and Azai Nagamasa (浅井長政), born in 1570 at Odani Castle in Ōmi Province. She belonged to the Azai clan, one of the great warrior houses of the Sengoku period, the century of civil war that ran from the mid-fifteenth century into the early seventeenth. Her life spans the collapse of that order and the establishment of the Tokugawa shogunate.

She was one of three sisters known collectively as the Azai sisters (浅井三姉妹), and all three became political actors of the first rank. Her elder sister Yodo-dono (淀殿) became the consort of Toyotomi Hideyoshi and mother of his heir; her younger sister Oeyo (江) married into the Tokugawa house. Ohatsu herself married Kyōgoku Takatsugu (京極高次), a daimyo whose domains placed him at the fault line between the two great powers of the age.

Her position was therefore unusual. Through blood she was tied to the Toyotomi; through marriage and her sister's marriage she was tied to the Tokugawa. That double attachment made her valuable as a channel of communication between two camps that were moving toward open war.

Life and Career

Ohatsu was born in the first year of the Genki era (元亀), 1570, the same year her father Azai Nagamasa broke with Oda Nobunaga. In 1573 Nobunaga destroyed the Azai house; Odani Castle fell, and Nagamasa died there. Ohatsu was three years old. She and her sisters were taken under Nobunaga's protection rather than killed, and they grew up inside the Oda political orbit.

Her marriage to Kyōgoku Takatsugu placed her in a family with its own strategic importance. Takatsugu held Ōtsu Castle, which commanded the Tōkaidō road between the capital and the east — the route any army marching between Kyoto and the Kantō region had to use. When war came in 1600, Takatsugu's allegiance mattered, and Ohatsu's family connections were part of the calculation.

The decisive phase of her career came in 1614–1615, during the two campaigns against Osaka Castle known as the siege of Osaka (大坂の陣). The Toyotomi stronghold held Hideyoshi's heir Hideyori and Ohatsu's sister Yodo-dono. Tokugawa Ieyasu moved to eliminate the Toyotomi entirely. Ohatsu, married into a Tokugawa-aligned house but sister to the woman inside Osaka Castle, served as a liaison between the two sides. She carried messages and negotiated in a situation where no other figure had standing with both parties.

The Tokugawa took Osaka Castle in 1615. Yodo-dono and Hideyori died there, and the Toyotomi line was extinguished. Ohatsu survived the fall of her sister's house. She lived on as a widow and a Buddhist nun, dying in Edo on 30 September 1633.

Why They Matter

Ohatsu matters because she is a rare documented case of a woman operating as a diplomatic channel in the highest politics of the Sengoku period. The Azai sisters as a group functioned as a network binding rival houses together, and Ohatsu was the member of that network positioned most directly between the Toyotomi and the Tokugawa.

Her usefulness to both sides rested on a fact that made her vulnerable: she was trusted by each camp precisely because she belonged to both. When the Toyotomi were destroyed in 1615, that dual belonging ceased to be an asset. The elimination of the Toyotomi removed the half of her family that gave her leverage, and she spent her remaining years in the Tokugawa capital.

Her career also shows how marriage worked as statecraft in this period. The placement of daughters was not incidental to war and alliance; it was one of the mechanisms by which alliances were built and maintained. Ohatsu's marriage to Kyōgoku Takatsugu was a strategic placement, and she performed the diplomatic work that placement implied.

The Name in Japanese

The name is written 常高院, read in kana as じょうこういん, and romanised as Jōkōin. The long ō in the second syllable is a long vowel, held roughly twice as long as a short o.

The three characters break down as follows:

• 常 — read here as じょう (jō). It means "constant," "unchanging," or "ordinary." In Buddhist usage it carries the sense of the eternal or the enduring.
• 高 — read here as こう (kō). It means "high" or "tall," and by extension "elevated" or "noble."
• 院 — read here as いん (in). It means "temple," "cloister," or "institution." Historically it also referred to a retired emperor or a cloistered noble, and it became a standard suffix in the posthumous names of women of high rank who took Buddhist vows.

The ending 院 is the key to reading the name correctly. 常高院 is not a birth name. It is a Buddhist name, the kind taken on entering religious life or conferred after death. Ohatsu was known in her youth as Ohatsu (お初) or Ohatsu-no-kata (お初の方), where の方 (no kata) is an honorific used for women of standing. The name 常高院 belongs to her later, posthumous or monastic identity, and it is the form by which she is most often referred to in historical writing.

Legacy

Ohatsu's legacy is bound up with the memory of the siege of Osaka. She is remembered as the woman who moved between the Tokugawa camp and the Toyotomi stronghold in the final negotiations before the castle fell, and as the sister who outlived the sister she could not save.

She died in Edo on 30 September 1633, eighteen years after the destruction of the Toyotomi. Her grave traditions and the temples associated with her name preserve the memory of a figure whose importance lay not in command or conquest but in connection — the family ties that made her, for a brief and decisive period, one of the few people both sides would listen to.
