Biography

Matsunaga Hisahide allied himself with Miyoshi Chōkei and rose to power under the Miyoshi clan.

In 1563, he betrayed the alliance by poisoning Chōkei’s son. Later, when Shogun Ashikaga Yoshiteru refused to grant him the political concessions he sought, Hisahide responded by besieging the shogun’s palace. During this conflict, the Miyoshi–Matsunaga alliance is recorded as employing arquebuses—marking one of the earliest uses of matchlock firearms by a Japanese faction in warfare.

In 1567, Matsunaga Hisahide became the first daimyō to construct a tenshu (tower keep) at his castle of Tamon, marking a significant development in Japanese castle architecture.

Soon afterward, Matsunaga Hisahide found himself at war with Miyoshi Yoshitsugu, the heir of the late Miyoshi Chōkei. However, in 1568, with the rising power of Oda Nobunaga and his entry into Kyōto, Hisahide was compelled to submit to Nobunaga’s authority.

In 1577, Matsunaga Hisahide initiated a rebellion against Oda Nobunaga following consultations with Uesugi Kenshin. Oda Nobunaga initially attempted to settle the dispute through diplomatic means, but Hisahide refused outright to receive the Oda envoy. In response, Nobunaga dispatched his son Oda Nobutada, along with Tsutsui Junkei, to lay siege to Shikisan Castle. Surrounded and outmatched, the castle was ultimately set ablaze and Hisahide committed seppuku. Following the seppuku of Matsunage Hisahide after the fall of the castle of Shikizan, his son Matsunaga Kojiro leapt to his death from the castle walls with his sword through his throat and Hisahide’s head in his hands.

Matsunaga Hisahide was also renowned as a connoisseur of the tea ceremony. According to legend, during the fall of Shigisan Castle, he deliberately smashed a priceless tea bowl, rather than allow it to be captured by his enemies. This dramatic act of defiance became a popular motif in Japanese art and woodblock prints, symbolizing both aesthetic devotion and warrior pride.
