(1301-1338) was the head of the Nitta family in the early fourteenth century, and supported the Southern Court of Emperor Go-Daigo in the Nanboku-cho period, capturing Kamakura from the Hōjō clan in 1333.

Long an enemy of Ashikaga Takauji, Nitta Yoshisada is often blamed for the split between the Northern and Southern Courts, as he fought against the Ashikaga and for the Emperor Go-Daigo. This rivalry came largely from the fact that the Ashikaga were ranked above the Nitta, despite their being descended from a younger ancestor; since the ancestors of the Nitta did not fight alongside their Minamoto cousins in the Genpei War, they were never accorded power or prestige at Kamakura.

In 1331, after being ordered by the bakufu (shogunate) to join an army at the Chihaya fortress, Nitta received summonses from Prince Morinaga and Emperor Go-Daigo to strike at the Hōjō, so he left his post. Returning to his home province of Kozuke, Nitta rallied the aid of other descendants & vassals including his brother Nitta Yoshisuke of the Minamoto clan, and began to march towards Kamakura through Musashi. On the approaches to the city, Nitta enjoyed some early victories, routing the Hōjō defenders and pursuing them towards the city.

The fall of Kamakura in 1333

Kamakura on land is completely surrounded by steep hills, making an army attack very difficult. Nitta first tried to enter through the Gokurakuji Pass and the Kewaizaka Pass, but concentrated Hōjō forces stopped him. Judging it impossible to enter by land, Nitta decided to try by sea bypassing the Inamuragasaki Cape on Sagami Bay, west of Kamakura. Once there, Nitta took advantage of a low tide and moved his men in through the beaches to the south but, according to the Taiheiki, he threw his sword into the surf and prayed to RyūjinIn describing this event, Japanese sources say Nitta Yoshisada prayed to a sea-god or Ryūjin, English sources almost always refer to Sun Goddess Amaterasu. The Taiheiki itself ( 稲村崎成干潟事) says:

Dismounting from his horse, Yoshisada removed his helmet and prostrating himself across the distant seas prayed to Ryūjin. "It is said that the lord of Japan from the beginning, Amaterasu Ōmikami, enshrined at Ise Jingū, hid herself within a Vairocana and appeared as Ryūjin of the vast blue seas. My lord (Emperor Go-Daigo) is her descendant, and drifts upon waves of the western sea due to rebels. I Yoshisada, in an attempt to serve as a worthy subject, will pick up my axes and face the enemy line. That desire is to aid the nation and bring welfare to the masses. Ryūjin of the Eight Protectorate Gods of the (seven) Inner Seas and the Outer Sea, witness this subject’s loyalty and withdraw the waters afar, open a path to the lines of the three armies.

He therefore speaks to Ryūjin who, he has heard, is manifestation of Amaterasu., who parted the waters for him.

The stele at , the tiny bay west of Inamuragaki, says:

666 years ago on May 21, 1333 Nitta Yoshisada, judging an invasion on land to be difficult, decided to try to bypass this cape. This is the place where, according to tradition, he threw his golden sword into the waves, praying the sea-god to withdraw them and let him pass.(Erected in 1917)

The city was taken, and the Hōjō clan's influence destroyed.

Following the fall of Kamakura (and of the Hōjō regency), Nitta was appointed Governor of Echigo and Vice-Governor of Harima and Kozuke Provinces, as Emperor Go-Daigo redistributed the Hōjō lands. Moreover, he courted Emperor Go-Daigo's secretary Kōtō-Naishi (匂当内侍), and married through the Emperor's mediation.

Death of Nitta Yoshisada

During the following few years, Nitta's rivalry with Ashikaga Takauji (and his brother Ashikaga Tadayoshi) came to a head, with the two planning rebellion, and issuing a call that "Nitta Yoshisada must be destroyed." They fought a number of battles, many of them in and around Kyoto, in the same locations as famous battles of the Genpei War; in the end, Nitta was defeated, but continued to be a thorn in Takauji's side until his death on July 2, 1338.

Nitta's death was as remarkable as his life. Turnbull (2003) writes that Nitta was fighting in the Siege of Kuromaru against Hosokawa Akiuji, an ally of Takauji, when his horse was felled by arrow fire. Nitta, pinned under the dead horse and unable to move was an easy target for archers. As a final act, Nitta drew his short sword and cut off his own head. Record has it that a number of his fellow samurai committed junshi seppuku nearby, in a show of allegiance.
