Nitta Yoshisada

Who They Were

Nitta Yoshisada (新田義貞, にった よしさだ) was a samurai lord of the early fourteenth century, born in 1301 and active through the end of the Kamakura period (1185–1333) into the Nanboku-chō period that followed. He was the head of the Nitta clan, a warrior family that traced its lineage to the Minamoto line, and he is sometimes known as Minamoto no Yoshisada. His father was Nitta Tomouji, and his mother was a foster daughter of Horiguchi Sadayoshi.

Yoshisada is best remembered as a decisive military commander who marched on Kamakura in 1333, besieged it, and captured it from the Hōjō clan, the regents who had dominated the shogunate. He later fought on behalf of Emperor Go-Daigo and the Southern Court, pitted against the Ashikaga brothers in a long and shifting campaign.

Life and Career

Yoshisada was born in 1301, in the third year of the Shōan era (正安). His birthplace is recorded in several locations: Ikushina, Satomi, and Hōsen. He rose to prominence as the head of the Nitta clan during a period of intense political crisis, when Emperor Go-Daigo sought to overthrow the Kamakura shogunate and restore direct imperial rule.

In 1333, Yoshisada led his forces east toward Kamakura, the seat of the Hōjō regency. He fought the Battle of Kotesashi and the Battle of Hakone-Takenoshita on the approach, then laid siege to the city itself. The campaign succeeded: Kamakura fell, and the Hōjō clan was destroyed. This victory made Yoshisada one of the principal military figures behind the Kenmu Restoration, the brief return of imperial authority under Go-Daigo.

The restoration did not hold. The Ashikaga brothers, led by Ashikaga Takauji, turned against the emperor, and Yoshisada was tasked with defending the Southern Court’s cause. What followed was a see-saw campaign in which the capital changed hands several times. Yoshisada fought at the Battle of Fujishima, the Battle of Teshimagawara, the Battle of Tegoshigawara, and the Battle of Minatogawa, among others. He also took part in the Battle of Teshimagawara, a separate engagement from the similarly named one, and the fighting swung back and forth without a decisive end.

Eventually, a peaceful compromise was agreed between the warring factions. As part of the settlement, Yoshisada was entrusted with two royal princes, a mark of the trust placed in him by the Southern Court. In 1337, he was at the Siege of Kanegasaki, where the situation turned disastrous. Both princes were killed during the siege, and Yoshisada’s own son also died there. Yoshisada himself managed to escape the collapse.

His escape did not last long. At the Siege of Kuromaru, his horse was killed beneath him. With no way to continue fighting, Yoshisada committed seppuku on August 17, 1338, at a place called Tōmyōji Nawate. He was thirty-seven years old.

Why They Matter

Yoshisada’s capture of Kamakura in 1333 was one of the pivotal events that ended the Kamakura shogunate and the Hōjō regency. Without that victory, Emperor Go-Daigo’s attempt to restore imperial rule would have lacked its most important military success. Yoshisada was, for a time, the emperor’s most reliable general in the field.

His later career is equally significant for what it reveals about the fragility of the Kenmu Restoration. The war against the Ashikaga brothers was not a simple contest between loyalists and rebels; it was a prolonged, shifting struggle in which the capital changed hands repeatedly. Yoshisada’s campaigns, including the battles of Minatogawa and Kanegasaki, defined the military geography of the early Nanboku-chō period. His death at Kuromaru in 1338 removed one of the Southern Court’s most capable commanders and marked a turning point in the conflict.

The Name in Japanese

The name is written 新田義貞 in kanji.

• Kana reading: にった よしさだ
• Romaji: Nitta Yoshisada

Character by character:

• 新 (にった, nitta): The character means “new.” In this surname it is read as part of the compound 新田, where it contributes the sense of “new field.”
• 田 (にった, nitta): The character means “rice field” or “paddy.” Together with 新, it forms the surname Nitta, literally “new field.” The reading にった is the surname reading of the compound, not the individual on-readings of the characters.
• 義 (よし, yoshi): The character means “righteousness,” “justice,” or “duty.” It is a common element in samurai given names, carrying connotations of moral correctness and loyalty.
• 貞 (さだ, sada): The character means “chaste,” “upright,” or “constant.” In names it often conveys steadfastness and integrity. The combination 義貞, read Yoshisada, pairs righteousness with constancy.

The full name, then, reads as “Nitta Yoshisada,” with the surname meaning “new field” and the given name meaning something like “righteous constancy.” The name fits the man: a lord whose reputation rests on loyalty to the imperial cause and a willingness to fight to the end.

Legacy

Yoshisada’s legacy is tied to the Southern Court and its doomed cause. He is remembered as one of the great loyalist generals of the Nanboku-chō period, a counterpart to figures like Kusunoki Masashige, who also died fighting for Emperor Go-Daigo. His capture of Kamakura is often cited as the decisive blow against the Hōjō, and his death at Kuromaru is treated as an example of samurai resolve.

His family continued after him. His sons Nitta Yoshioki, Nitta Yoshiaki, and Nitta Yoshimune carried on the clan name, and a daughter married into the Chiba family. The Nitta clan’s fortunes declined with the Southern Court, but Yoshisada’s name remained a reference point for later generations of warriors who valued loyalty to the throne. In the centuries that followed, he was celebrated in military chronicles and popular literature as a model of the loyal general who gave everything for his sovereign.
