Bio Fuchibe Yoshihiro

Following the collapse of the Kamakura shogunate in 1333 at the hands of Ashikaga Takauji (足利尊氏, 1305–1358) and Nitta Yoshisada (新田義貞, 1301–1338), Emperor Go-Daigo (後醍醐天皇, 1288–1339) launched the Kenmu Restoration (建武の新政), briefly restoring imperial rule. In the east, the Kamakura shogunal office (鎌倉将軍府 Kamakura-shōgunfu) was established to oversee Kantō, with Tadayoshi serving as its military governor. Yoshihiro served under Tadayoshi's command in Kamakura, where his name would become entwined with one of the Restoration's most haunting legends—the death of Prince Moriyoshi (護良親王, 1308–1335).

According to the Taiheiki (太平記), when the prince was confined at Tōkō-ji Temple (東光寺) in Kamakura after his political downfall, Tadayoshi, fearing that the imprisoned royal might be rallied as a symbolic leader by the rebel Hōjō Tokiyuki (北条時行, 1322–1353), ordered Yoshihiro to execute him. The chronicle recounts how the samurai entered the earthen cell and attempted to strike down the prince, only for Moriyoshi to bite through the sword blade in defiance. After a desperate struggle, Yoshihiro decapitated him, but when he carried the head into the moonlight, its eyes glared back as if still alive. Shaken by the sight, he decided that such a head should never be shown to his lord and, recalling the ancient Chinese tale of the swordsmiths Gan Jiang and Mo Ye (干将・莫耶), he cast it into a nearby bamboo grove. The grove, known as Okamae-dokoro (御構廟), still forms part of the grounds of Kamakura-gū Shrine (鎌倉宮), built centuries later on the temple's site.

Another local tradition, however, preserves a very different version of Yoshihiro's actions. It claims that he disobeyed Tadayoshi's command out of pity for the prince and secretly spirited him away from Kamakura, eventually helping him escape north to Ishinomaki in present-day Miyagi Prefecture. Aware that his defiance would endanger his family, Yoshihiro is said to have renounced his ties to them, parting from his wife and children beneath a great hackberry tree by a bridge over the Sakai River (境川), marking the boundary between modern Sagamihara and Machida. The spot, later known as Wakare-bashi ("Parting Bridge"), became the site of the "Enkiri-enoki" — the "Severance Hackberry" — which still stands as a relic of that farewell.

A second legend from the region tells of Yoshihiro's battle against a dragon that had taken up residence in a pond called Ryūike (龍池) along the same river, terrorising the surrounding villages. He is said to have led his men in pursuit and slain the creature by shooting an arrow into its eye. The dragon's body, according to the story, split into three parts that fell in different locations, prompting the construction of three temples — Ryūtō-ji (龍頭寺), where the head fell, Ryūdō-ji (龍胴寺, now Ryūzō-ji 龍像寺), where the body landed, and Ryūbi-ji (龍尾寺), where the tail was said to have struck the ground — to calm its vengeful spirit. Only Ryūzō-ji remains today, where the tale continues to be told, and an old stretch of the Kamakura Highway near the Sakai River is still remembered as the place "where the dragon was shot."

Yoshihiro's life ended amid the chaos of the Nakasendai no Ran (中先代の乱 ) in 1335, when Hōjō Tokiyuki, son of the last Hōjō regent, rose against the Ashikaga. As the Hōjō army pressed toward Kamakura, Tadayoshi fled westward to Suruga, ordering Yoshihiro to ensure that Moriyoshi could not be used as the rebels' rallying figure. This act sealed the prince's fate. After the fall of Kamakura, Ashikaga Takauji returned from Kyoto , crushed the Hōjō forces, and soon rebelled against Emperor Go-Daigo, setting the stage for the division between the Northern and Southern Courts (南北朝 Nanbokuchō). Yoshihiro continued to serve in Tadayoshi's forces during these campaigns but was eventually killed in battle at Tegoshi-gawara (手越河原) in Suruga. According to the Nantaiheiki (難太平記), he charged into enemy lines and fell fighting while covering his lord's retreat.

Fuchibe Yoshihiro remains a shadowy but compelling figure — remembered at once as a loyal retainer, a reluctant executioner, a dragon-slayer, and a man whose name lingers in the place-names, temples, and riversides of Sagami's old countryside.
