Château de Mihara
fondateur · 1567-1597
→One of the five great regents of Toyotomi Hideyoshi
Kobayakawa Takakage, third son of Mōri Motonari, was adopted in 1544 by the Takehara branch of the Kobayakawa clan, and in 1550 by the main Nuta branch, whose leadership he assumed at Takayama mountain castle. Together with his brother Kikkawa Motoharu, he formed one of the two pillars on which the power of the Mōri rested, Takakage in particular commanding the clan's naval forces on the Seto Inland Sea. His castles trace the development of military architecture in his time: he left Takayama for Niitakayama, built in 1552 on the opposite ridge, and in 1567 began the construction of Mihara castle, a sea fortress built on linked islets that became his principal residence from the 1580s. Having declared for Toyotomi Hideyoshi, he received the province of Chikuzen and settled at Najima, before returning to Mihara for his retirement in 1596, where he further enlarged the castle. He died there in 1597.
Research by the University of Hiroshima highlights the contrast between Takakage's successive castles. Takayama and Niitakayama, perched on ridges on either side of the Nuta, favoured defence; Niitakayama already shows stone walls and building foundations that anticipate the castles of the early modern period. Mihara, by contrast, opens onto the sea: built on islets, it combines enclosures and a military harbour, reflecting Takakage's role at the head of the Mōri fleet.
