Kusunoki Masatsura

Birth of the Young Kusunoki and His Father's Instruction

Born around 1326 (Karyaku 1) as the legitimate son of Kusunoki Masashige, Kusunoki Masatsura became known as the "Young Kusunoki" (Shō-Nankō), a loyal subject of the Southern Court remembered through the generations. His father, Masashige, was renowned as the "Great Kusunoki" for his unwavering devotion to Emperor Go-Daigo and stood as a central military commander supporting the Kenmu Restoration. Masatsura engraved upon his very bones the teachings imparted by his father, whose words at the Battle of Minato River resonated forever in his heart: "Even if reborn seven times, serve the Emperor." These words became the compass of Masatsura's entire life and remained his unwavering guide until the moment he fell at Shijōnawate.

Inheriting His Father's Legacy

In 1346 (Shohei 1), Kusunoki Masatsura gained the trust of Emperor Gomurakami of the Southern Court and took his place as a principal commander of the Southern Court forces. As tensions mounted with the Northern Court army led by Kō Moronao and his brother Moroyasu of the Muromachi Shogunate, Masatsura launched aggressive offensives against Northern forces across Settsu, Kawachi, and Izumi. In the battles of Sumiyoshi and Tennō-ji, he defeated Kō Moronao's armies and won victory after victory in succession. During this period, Masatsura's exploits recalled the very tactics of his father, Masashige—a warrior who had faced vastly superior Northern forces with bold stratagems and tactical mobility.

The Farewell at Nyoirin-dō—A Death Poem's Vow

In 1348 (Shohei 3), as it became clear that Kō Moronao was launching a final, overwhelming offensive against the Southern Court, Masatsura refused to retreat despite knowing the vast disparity in forces. Before departing for battle, he and his clan and retainers made pilgrimage to Nyoirin-dō temple at Yoshino and carved his death poem upon the temple door:

"I shall not return—knowing this, I draw the catalpa bow; even as I join the dead, let my name live on."

This single poem, which distilled both Masatsura's resolve and his yearning for his father, endured as a masterpiece that continues to move the hearts of people even seven centuries later.

The Fierce Battle at Shijōnawate and a Glorious Death

On January 5, 1348 (Shohei 3), the Southern Court army under Masatsura's command clashed with Kō Moronao's Northern forces at Shijōnawate (present-day Shijōnawate, Osaka Prefecture). Against a Northern army many times larger in number, Masatsura charged frontally. In the fierce fighting, many of his clan members, including his younger brother Masatoki, fell one after another in battle, and Masatsura himself received a mortal wound. At the exhaustion of his strength, Masatsura died together with his brother in an act of seppuku. He was but twenty-three years of age—or possibly twenty-two. This glorious death came to be celebrated in later ages as the very pinnacle of loyalty, and for the patriots of the Meiji Restoration, the sacrifice of the Kusunoki father and son became a spiritual pillar.

His Swords and Martial Prowess

Masatsura's martial prowess was cultivated through the instruction of his father, Masashige, and he is said to have excelled in horsemanship, archery, and swordsmanship alike. Few definitive heirlooms from the swords Masatsura possessed have been preserved, yet it is believed that the blades held by the Kusunoki family—both tachi and uchi-katana—were excellent works in either the Yamato or Yamashiro style. The sword "Kusunoki Kanemitsu," forged by Kanemitsu of Osafune in Bizen Province and associated with his father Masashige, is particularly renowned. The swords of the Kusunoki family were carefully passed down as both the pride of the warrior house and a symbol of devotion to duty. It is said that the blade Masatsura wore at the Battle of Shijōnawate was the very sword he used in his final act of seppuku, and its spirit, along with other relics of Kusunoki Masatsura preserved at Yoshimizu Shrine, continues to be transmitted to the present day as a testament to loyalty to the Southern Court.

The Legacy of a Loyal Servant and His Influence on Posterity

Throughout the Edo period, the life of Kusunoki Masatsura—a warrior who upheld righteousness despite knowing the battle was hopeless—became the very model and exemplar of the samurai way. Within the thought of the Mito School and reverence for the emperor, Kusunoki father and son were elevated to divine status as embodiments of righteous cause, and from the Meiji era onward they were enshrined as national heroes at Yasukuni Shrine and Shijōnawate Shrine. His death poem was quoted and imitated by countless warriors and patriots, and his spirit remained at the very core of Japanese bushido from the sonnō-joi movement of the late Edo period through the closing days of the Pacific War.
