The Itami Family and Hosokawa Takakuni and Oriental Melons
1. The Itami Family and the Collapse of Takakuni
The Itami family ruled the surrounding region from their stronghold, Itami Castle. Their name first appears in historical records in 1309, during the Kamakura period (1185–1333), when Itami Chikamori served the deputy military governor (shugodai) of Settsu Province. Later, during the Nanboku-cho period (1336–1392), Itami Saemon-no-jo was recorded in 1363. On June 4, 1531, Itami Kunisuke fell in battle when Hosokawa Takakuni (1484–1531)—the 31st Kanrei (Shogunal Deputy) of the Muromachi Shogunate and 15th head of the Kyocho-Hosokawa family—was defeated by the allied forces of Hosokawa Harumoto and Miyoshi Motonaga (1501–1532).
In 1521, at the height of his power, Takakuni deposed the 10th shogun, Ashikaga Yoshitane (1466–1523), replacing him with Yoshiharu (1511–1550, the 11th shogun), son of the 8th shogun, Ashikaga Yoshizumi (1480–11511). Yet, as the saying goes, light is always accompanied by shadow. In July 1526, Takakuni’s cousin, Hosokawa Tadakata (d. 1531), fabricated allegations that Takakuni’s key retainer, Kozai Motomori (d. 1526), was in secret communication with Hosokawa Harumoto (1514–1563). Tadakata’s exact motives remain unknown, though Motomori was said to be unrefined and uneducated. Flying into a rage, Takakuni had Motomori assassinated.
This act enraged Motomori’s brothers, Hatano Motokiyo (d. 1530) and Yanagimoto Kataharu (d. 1530), who promptly rebelled in their home province of Tanba. Motokiyo fortified Yakami Castle, while Kataharu held Kannosan Castle. Stunned by the uprising, Takakuni ordered Tadakata to lay siege to Kannosan Castle, while dispatching Kawarabayashi Shurinosuke and Ikeda Danjo to Yakami Castle on October 23. Skirmishes persisted for days. On November 5, Naito Kunisada (d. 1553), lord of Yagi Castle who sympathized with the brothers, withdrew his forces from the encirclement of Kannosan Castle. On November 30, Akai Goro, lord of Kuroi Castle, struck and broke the siege. As Takakuni’s troops retreated, infighting broke out between Shurinosuke and Danjo, while Tadakata simply fled. Within six months, the political fragility of Takakuni’s regime stood fully exposed.
2. The Miyoshi Intervention and the Seesaw War
The Miyoshi family was swift to exploit this vulnerability. As if acting in concert with Motokiyo and Kataharu, Miyoshi Masanaga (1508–1549) landed at Sakai as early as December 13, seizing Hori Fortress—a stronghold situated on an island in the Yodo River, near present-day Juso Park.
Following a series of dramatic political reversals and the ongoing decline of the Muromachi Shogunate, Takakuni went into exile, wandering through Iga, Ise, Echizen, Izumo, and Bizen provinces. He eventually secured the backing of Uragami Muramune (1498–1531), a powerful warlord based at Mitsuishi Castle in Bizen. Rebuilding his strength, Takakuni and Muramune occupied Harima Province on July 27, 1530, captured Itami Castle by late February 1531, and reclaimed Kyoto on March 7. They then advanced toward Sakai in Izumi Province, the seat of Ashikaga Yoshitsuna (1511–1573)—known as the "Sakai Shogun"—who exercised a degree of shogunal authority.
A fierce, seesaw struggle ensued. On June 2, Akamatsu Harumasa (1495–1565), stationed at Okishio Castle, arrived at Kannoji Temple and was welcomed that evening by Takakuni and Muramune. However, on June 4, Harumasa unexpectedly defected to the Sakai Shogunate. Caught in a pincer attack—with Harumasa striking from the north and the Sakai forces pressing from the south—Takakuni’s army collapsed.
3. The Tragedy of Itami Kunisuke and the Downfall at Daimotsu
Itami Kunisuke lost his life in the chaotic melee. Was his sacrifice born of loyalty to Takakuni? Hardly. He was simply swept away in a self-serving struggle for survival. The Hosokawa Ryoke-ki (Chronicle of the Two Hosokawa Houses), written by Ikushima Sochiku and covering events from 1504 to 1570, captures the horror of the scene: "The river was so choked with corpses that it resembled a burial mound. People said that such a disaster was unprecedented—unheard of in the past, present, or future." Driven by ambition, Kunisuke had submitted to Takakuni, earning the honorific character "Kuni" (国) for his name, only to realize too late that he had jumped onto a sinking ship.
With his primary retainers slain, Takakuni fled the battlefield in ruin toward Amagasaki. He sought refuge at Daimotsu Castle, only to find it already occupied by Akamatsu forces. Desperate, he hid in an indigo dyeing shop called Kyoya, turning a large ceramic indigo pot upside down and crouching underneath it. On June 5, Miyoshi Kazuhide (d. 1532) arrived in search of him.
Knowing children were playing nearby, Kazuhide brought out a basket of oriental melons (makuwauri) and promised: "If you tell me where Takakuni is hiding, all of these melons are yours." Tempted by the sweet fruit, the children revealed his hiding place.
At around 4:00 a.m. on June 8, at the age of 48, Takakuni committed ritual suicide at Kotoku-ji Temple in Amagasaki. In his farewell poem (jisei), sent to Kitabatake Harutomo (1503–1563), he wrote:
The painted seas and mountains shown,
The landscapes sculpted into stone—
Even beyond the mortal space,
Shall my open eyes guard this place?
