Notable people

Historical figures

Numazu's historical significance in pre-modern Japan is closely tied to several key figures who influenced regional governance, military defense, and the development of strategic sites along the Tōkaidō road. These individuals, primarily from the Sengoku and Edo periods, shaped the area's role as a vital post station and fortress in Suruga Province. Hōjō Sōun (1432–1519), originally known as Ise Shinkurō, was a pivotal warlord who founded the Later Hōjō clan and launched his ascent to power from Kōkokuji Castle in Numazu around 1487. Granted the castle by the Imagawa clan for his military services, Sōun used it as a base to expand Hōjō influence across eastern Japan, establishing control over parts of Suruga Province through alliances and conquests. His strategic occupation of the region contributed to Numazu's emergence as a defensive outpost, laying groundwork for later feudal administrations in the area. In the late , (1543–1582), the successor to the renowned warlord , fortified Numazu by constructing Sanmaibashi Castle in 1579 as a naval stronghold to counter invasions from the rival based at nearby Nagahama Castle. This fortification, located at the mouth of the Kano River, served as a key eastern defensive position for the Takeda during their brief control of Suruga, enabling resistance against Hōjō naval assaults for several years. Katsuyori's efforts underscored Numazu's military importance along the Tōkaidō corridor, though the castle fell after the Takeda's defeat in 1582. During the Edo period, Mizuno Tadatomo (1731–1802), a hereditary retainer of the Tokugawa shogunate, became the first daimyō of Numazu Domain in 1777, receiving 20,000 koku of land and authorization to rebuild Numazu Castle on the site of the former Sanmaibashi fortifications. As lord, Tadatomo oversaw local governance, including the management of the Numazu post station on the Tōkaidō road, which facilitated travel and trade between Edo and Kyoto under shogunal oversight. His reconstruction of the castle in 1777 marked a shift toward peaceful administration, with the Mizuno clan retaining control until the Meiji Restoration, contributing to the region's stability as a fudai domain.
