Azai Sukemasa

Who They Were

Azai Sukemasa (浅井亮政) was a samurai and daimyō of the Sengoku period, the long era of civil war that ran from the late fifteenth into the late sixteenth century. He was born in 1491, in the third year of the Entoku era, and died on 21 January 1542. His life fell entirely within the Muromachi period, the span of Japanese history from 1336 to 1573 during which the Ashikaga shoguns ruled from Kyoto.

Sukemasa was the head of the Azai clan, a warrior house based in Ōmi Province, the region around the southern end of Lake Biwa. His father was Azai Naotane, and his mother was a daughter of Akao Norimasa. He held the position of daimyō — a regional warlord who governed territory and commanded his own military force — and his occupation was that of a samurai.

He married two women, Nishi Kōan and Azai Kuraya, and had many children. Among them were Azai Hisamasa, who succeeded him as clan head, and several daughters and sons whose names survive in the record, including Azai Takamasa, Azai Matsuichi, Azai Tsuruchiyo, and a daughter who married Kyōgoku Takahide.

Life and Career

The Azai began as retainers of the Kyōgoku clan, a more powerful house that dominated northern Ōmi. Sukemasa served the Kyōgoku, but the clan's fortunes turned when its leaders fell into a dispute over the succession. A house divided against itself could not hold its retainers, and the Azai rose as the Kyōgoku declined.

Sukemasa emerged from that collapse as the effective ruler of the Azai and took the title of daimyō. This was a familiar pattern in the Sengoku period: a retainer house, watching its overlord weaken, steps into the vacuum and claims the territory and authority for itself. Sukemasa's achievement was to make that transition stick, turning a family of subordinates into a ruling clan.

He died on 21 January 1542. His son Azai Hisamasa took over as head of the clan that same year.

Why They Matter

Sukemasa founded the Azai as an independent power. Before him, the family served the Kyōgoku; after him, the Azai were lords in their own right, and the position passed to his son. That change of status is the single fact that defines his career.

His importance to later history lies partly in what he handed down. The Azai domain he established became, under his grandson Azai Nagamasa, one of the notable powers of the Sengoku period, tied by marriage to Oda Nobunaga's family before turning against him. None of that would have been possible had Sukemasa not first broken the Azai free of the Kyōgoku.

The contrast with his successor is equally instructive. Hisamasa inherited the clan in 1542 but was never a strong leader. He lost territory to the Rokkaku clan and ended by becoming a Rokkaku retainer — the same subordinate position his father had escaped. The Azai's rise under Sukemasa and their partial reversal under Hisamasa show how quickly a Sengoku house could gain or lose standing depending on the abilities of the man at its head.

The Name in Japanese

The name is written 浅井亮政. It is read in kana as あざい すけまさ, and in romaji as Azai Sukemasa. The family name comes first, as is standard in Japanese; the given name follows.

浅 (read あざ, aza, in this name) — "shallow." This is the first character of the clan name 浅井. On its own the kanji commonly carries the reading あさ (asa), meaning shallow, as in shallow water. In the surname it takes the voiced reading あざ.

井 (read い, i, in this name) — "well," as in a well for drawing water. Together, 浅井 (Azai) literally suggests "shallow well." Place names and family names of this kind are common in Japan, and the meaning of the individual characters rarely describes the family itself.

亮 (read すけ, suke, in this name) — "bright," "clear," or "evident." This is the first element of the given name. It is a common character in male personal names of the period, and it can also be read あきら (akira) or りょう (ryō) in other contexts.

政 (read まさ, masa, in this name) — "government," "administration," or "rule." This is the second element of the given name. It appears constantly in the names of Sengoku warlords, and it carries the sense of governing or setting affairs in order.

So the full name breaks down as: 浅井 (Azai, the clan name, "shallow well") plus 亮政 (Sukemasa, the given name, "bright rule" or "clear governance"). The reading すけ for 亮 and まさ for 政 are both conventional name readings (nanori) rather than the everyday readings of those characters, which is typical of warrior names from this era.

Legacy

Sukemasa's direct legacy was the clan itself. He left the Azai as a ruling house with a defined territory in Ōmi, and he left a son, Azai Hisamasa, to inherit it in 1542. The line continued through Hisamasa to the next generation, and the Azai name remained a factor in the politics of central Japan long after Sukemasa's death.

His own reputation rests on the rise rather than the rule. He took a retainer family and made it a daimyō house, and he did so by exploiting the internal divisions of his former overlords, the Kyōgoku. That achievement did not outlast him intact — Hisamasa lost ground to the Rokkaku and ended as their retainer — but the clan Sukemasa founded endured beyond his son's setbacks, and it is for founding it that he is remembered.
