大道寺政繁
Hōjō elder and keeper of Kawagoe Castle — a linchpin of Hōjō rule in the Kantō who fell with Odawara
Description
Origins and House
Daidōji Masashige (1533-1590) was head of the Daidōji, a house of senior retainers to the Later Hōjō of Odawara. The Daidōji had followed Hōjō Sōun since his move into Izu, and as a hereditary vassal line were counted among the "six houses of distinguished lineage" within the clan, holding high standing across generations.
Keeper of Kawagoe Castle
Masashige served as castle keeper (jōdai) of Kawagoe Castle, a strategic strongpoint in Musashi Province, and thus helped administer Hōjō rule over the province. Besides governing the districts around Kawagoe and overseeing temple and shrine affairs, he is recorded as having served as deputy (daikan) of Kamakura. He later became lord of Matsuida Castle in Kōzuke Province, entrusted with the western edge of the Hōjō domains and its defences facing Shinano and Kōzuke. His long stewardship of key Kantō positions made him one of the most powerful figures among the Hōjō retainers.
The Odawara Campaign and His End
When Toyotomi Hideyoshi launched the Siege of Odawara in 1590, Masashige held Matsuida Castle against the northern armies of Maeda Toshiie and Uesugi Kagekatsu. Outnumbered, he surrendered the castle, and thereafter served the Toyotomi side as a guide in the reduction of other Hōjō strongholds including Hachigata and Hachiōji castles. After Odawara capitulated he was held responsible for having opened hostilities and was ordered to commit seppuku, meeting his end at Jōrakuji in Kawagoe. (An alternative account places his execution at Sakurada in Edo; the circumstances are not conclusively established.) He was 58.
Legacy
Assessments of Masashige remain divided: he was among the foremost elders upholding Hōjō rule in the Kantō, yet after his surrender he joined in the assault on his former lord's castles. At the same time, attention is given to his role as an administrator who ran the practical business of domain governance for years as keeper of Kawagoe and lord of Matsuida, and he is remembered as a figure who laid groundwork for Kawagoe before its early-modern development.
