Hirano Nagayasu

Who They Were

Hirano Nagayasu (平野長泰, ひらの ながやす) was a samurai who served Toyotomi Hideyoshi during the Azuchi–Momoyama period, the decades of unification wars that preceded the Tokugawa shogunate. He was born in 1559 in Tsushima, the son of Hirano Nagaharu (平野長治). His career is defined by a single afternoon of fighting in 1583, at the Battle of Shizugatake, which made him one of the seven warriors celebrated as the Shichi-hon-yari (七本槍, しちほんやり), the "Seven Spears of Shizugatake."

He lived through the transition from Hideyoshi's rule to Tokugawa Ieyasu's, fighting for the Tokugawa at Sekigahara in 1600 and later seeking to rejoin the Toyotomi side at the Siege of Osaka in 1614. He died on 8 June 1628. His heir was Hirano Nagakatsu (平野長勝).

Life and Career

Nagayasu was born in 1559, in the second year of the Eiroku era (永禄, えいろく), during the Muromachi period. His birthplace, Tsushima, lay in the thick of the Sengoku civil wars, and his father, Hirano Nagaharu, was a samurai of the Hirano family. Nagayasu entered the service of Toyotomi Hideyoshi, the general who would complete the unification of Japan.

The decisive moment came in 1583 at the Battle of Shizugatake, fought between Hideyoshi and Shibata Katsuie. Nagayasu fought with enough distinction that he was counted among the seven warriors later known as the Shichi-hon-yari, the Seven Spears of Shizugatake — a group remembered as some of Hideyoshi's most trusted commanders. For his performance in the battle he was rewarded with an additional 3,000 koku (石, こく), the standard measure of a samurai's landed wealth, roughly the rice needed to feed one person for a year.

In 1600, at the Battle of Sekigahara, Nagayasu fought in the Eastern Army under Tokugawa Ieyasu, the side that won and that went on to found the Tokugawa shogunate. Fourteen years later, in 1614, he reversed course: he asked to serve the Toyotomi clan at the Siege of Osaka, the final campaign against Hideyoshi's heirs. The request was refused. In the Edo period that followed, he became a hatamoto (旗本, はたもと), a samurai in direct service to the Tokugawa shogunate. He died on 8 June 1628.

Why They Matter

Nagayasu belongs to the generation of samurai whose careers spanned the whole arc of unification: the wars of the 1580s under Hideyoshi, the decisive Tokugawa victory at Sekigahara in 1600, and the last stand of the Toyotomi at Osaka in 1614. His name survives chiefly through the Seven Spears of Shizugatake, a group whose reputation became a template for the ideal of the loyal, battle-tested retainer.

His career also shows how fluid allegiance could be in this period. He fought for the Tokugawa in 1600 and then sought to fight for the Toyotomi in 1614 — a shift that reads as opportunism to modern eyes but was a normal feature of a world in which warrior houses balanced obligation, reward, and survival. The refusal of his 1614 request spared him the fate of the Toyotomi cause at Osaka.

As a hatamoto under the Tokugawa, he represents the institutional turn that followed the wars: the absorption of the surviving warrior class into a hereditary, salaried military bureaucracy. His son, Hirano Nagakatsu, carried the family line forward.

The Name in Japanese

The full name is written 平野長泰, read in kana as ひらの ながやす, and romanised as Hirano Nagayasu. In Japanese name order the family name comes first: Hirano is the surname, Nagayasu the given name.

平 — read hira here. It means "flat" or "level." It is a common element in Japanese place names and surnames.

野 — read no here. It means "field" or "open country." Together, 平野 (Hirano) means something like "flat field" or "plain," and it is also an ordinary Japanese word for a plain or open expanse.

長 — read naga here. It means "long" or "chief/senior." In names it frequently appears in the reading naga, as in this name.

泰 — read yasu here. It means "peaceful," "calm," or "prosperous." It is a common closing element in male given names, often carrying a wish for tranquility or good fortune.

So the given name 長泰 (Nagayasu) combines "long" with "peaceful" — a name meaning roughly "enduring peace." The family name 平野 (Hirano) is a plain or flat field. Note that the surname's first kanji, 平, also appears in Taira (平), the great warrior clan, though the two are not necessarily connected.

Legacy

Nagayasu's lasting association is the Shichi-hon-yari, the Seven Spears of Shizugatake. The phrase itself is worth unpacking: shichi (七) is "seven," hon (本) is the counter for long objects such as spears, and yari (槍) is "spear." The seven were singled out from Hideyoshi's forces after the 1583 battle and became, in later telling, a byword for elite service under the Toyotomi.

His reward of 3,000 additional koku after Shizugatake places him among the warriors whose fortunes were made by that single engagement. The figure also gives a concrete sense of how military success was converted into wealth in this period: land and rice, measured in koku, were the currency of samurai status.

He outlived Hideyoshi, fought for the Tokugawa at Sekigahara, was refused a place at Osaka, and ended his life as a hatamoto, dying on 8 June 1628. The Hirano family continued through his son, Hirano Nagakatsu. For students of Japanese, his name is a compact lesson in how surnames, given names, and honorific titles such as Shichi-hon-yari are built from ordinary kanji with concrete meanings.
