三木城（別所城）
Miki Castle (Bessho Castle) is a historic castle in kinki dating from the Founded during the Nanbokuchō period as Bessho clan seat; fell to Hashiba Hideyoshi's siege by starvation (Miki no Hoshi-goroshi) 1578–1580, whose lord was Bessho Nagaharu (defender) → Hashiba Hideyoshi (besieging Oda forces).
Overview
Miki Castle (Bessho Castle) in Hyogo Prefecture is the site of one of Hashiba Hideyoshi's most methodical and pitiless military campaigns — the "Miki no Hoshi-goroshi" (Starvation of Miki), a siege-by-famine lasting nearly two years that became a template for Hideyoshi's subsequent conquests of Tottori and Takamatsu.
Bessho Nagaharu, lord of Miki Castle and head of the Bessho clan, was the preeminent local lord of Harima Province (southern Hyogo). When Oda Nobunaga dispatched Hashiba Hideyoshi to bring Harima under control in 1578, Nagaharu defected to the Mōri side rather than submit, allying with Araki Murashige and other disaffected Kinai lords. The defection threatened Nobunaga's entire western strategy.
Hideyoshi responded by constructing an elaborate network of subsidiary forts (tsukeshiro) completely encircling Miki Castle — cutting off every supply route and condemning the castle's population to slow starvation. The siege lasted from 1578 to January 1580: twenty-two months of progressive famine during which the castle's garrison and townspeople steadily diminished from hunger and disease.
In January 1580, Bessho Nagaharu negotiated a surrender: he would take his own life in exchange for the lives of the remaining garrison and townspeople. His suicide at age 21, sacrificing himself to save hundreds of others, transformed the defeated lord into a figure of tragic nobility. Miki Castle subsequently became one of the most emotionally resonant sites in Japanese military history — a place where the human cost of Sengoku unification is written in its most stark terms.
The castle site is a National Historic Site with earthworks, dry moats, and the main bailey area preserved. Miki City honors Nagaharu with memorials, statues, and an annual commemoration.
Connection to Swords
Miki Castle's relationship with Japanese blades can be understood through the sword-making culture of Harima, the province where the castle stood, and the historical context of its lord, Bessho Nagaharu. Harima Province (southern Hyogo) was known as a sword-making center, called "Harima-mono," and metalworking communities of smiths had existed throughout the region since the medieval period. The central Harima area, including Miki City, remains to this day the heart of the "Miki carpentry tools and edged metalwork" industry, and the tradition of metalworking and smithcraft from the medieval period has been inherited by the modern edged-tool production known as "Miki metalwork." Regarding the origins of Miki's tool industry, one theory traces it to smiths and carpenters brought by Hideyoshi's forces during the "Miki Campaign," who then settled in the castle town, establishing a historical continuity between the siege and the development of the sword and tool industry. The Bessho clan, as powerful regional lords of Harima, commanded numerous retainers, and their procurement of armor and blades was closely linked to Harima's smithcraft culture. Since the medieval period, swordsmiths have been active throughout Harima. After the Miki Campaign, as Hideyoshi brought the whole of Harima under his rule, the metalworking smiths of Harima were incorporated into Hideyoshi's military production. Following Hideyoshi's unification of Japan, the smiths of the Miki region specialized in the production of agricultural tools and edged metalwork, laying the foundation for the "Miki carpentry tools" industry that has continued from the Edo period to the present day. This progression can be understood in the context of Miki Castle as a symbolic example of Japanese metal culture's history—the transformation "from Sengoku swordsmiths to modern edged-tool industry."
