INTERACTIVE BATTLE
Collapse at Daimotsu
6th month, 4th day to 8th day, Jōroku 4 (June 1531) · Daimotsu, Settsu Province (Amagasaki)
Hosokawa Harumoto and Miyoshi Motonaga defeated Hosokawa Takakuni and Uragami Muramune in Settsu Province; Takakuni was captured at Amagasaki and committed suicide.
Background
Hosokawa Takakuni, who had been driven from Kyoto in the Battle of Katsukawarahara in Daiei 7 (1527), allied with Uragami Muramune of Harima Province and briefly recovered Kyoto. However, his conflict with Hosokawa Harumoto and Miyoshi Motonaga continued, and in the 6th month of Jōroku 4 (1531), both armies engaged in a decisive battle in the Settsu region.
Outcome
On the 4th day, Miyoshi Motonaga's forces launched their attack from Tennōji and Abeno, crushing Takakuni's army and pursuing them toward Nakajima and Noriokawa. Takakuni's forces suffered numerous casualties while crossing the river, and during the battle, the Akamatsu contingent in the rear defected to Harumoto's side, causing Takakuni's army to collapse completely. Takakuni fled to Amagasaki and went into hiding, but was captured and committed suicide at Kōtokuji Temple in Daimotsu on the 8th day.
Course of the battle
1 June 5 (Capture) / June 8 (Suicide)
Takakuni Captured and Commits Suicide at Kōtokuji
The routed Hosokawa Takakuni fled to a merchant house in Amagasaki and went into hiding, but was captured and committed suicide at Kōtokuji Temple in Daimotsu.
Points of debate
The name of the merchant house (either 'Konoya' or 'Kyōya') where Takakuni hid is treated as uncertain even in existing notes; it remains unconfirmed.

Historical significance
With the collapse at Daimotsu, Hosokawa Takakuni was eliminated, and Hosokawa Harumoto and Miyoshi Motonaga gained hegemony over the Kinai region. However, Motonaga himself was attacked by Ikkō Ikki forces in the following year (1532) and committed suicide; Kinai politics continued to undergo reorganization until the Battle of Eguchi (1549).

Notes on the data
The phases of initial engagement (Tennōji and Abeno), pursuit and retreat (Nakajima and Noriokawa), and rear defection remain at broad-scale locations in available sources and cannot be pinpointed precisely; therefore, only the conclusion (Amagasaki and Daimotsu) is shown on the map. The identity of individual commanders in the rear contingent that defected is not specified in available sources, which only note 'defection of Akamatsu forces'; therefore, this text also does not name specific individuals.
