Sekidousan Castle




Sekidōsanjō is thought to have been built by Uesugi Kenshin in 1578 as part of his strategy to take Nanaojō. It is thought also to have been used by shugenja and so-called warrior monks (probably laymen fighting for monks). Following the death of Oda Nobunaga in 1582, the Hatakeyama Clan revolted and siezed the fort but they were besieged and defeated by Meada Toshiie and Sakuma Morimasa, and Sekidōsanjō was destroyed. Maeda Toshiie contributed to the rebuilding of the mountain worshippers' community but it was destroyed in modern times by the Meiji revolutionaries (ishigaki and other ruins remain spread across the mountain slope and are extensive; the castle ruin is towards the top of the mountain and one passes many temple ruins to reach it).

Visit Notes

Sekidōsanjō is a castle ruin overlooking a fortified monastic community centered around Ōmiyabō (now reconstructed). There is a main bailey ringed by residual dorui (earthen embankments) and surrounded at the base of the ramparts by a karabori (dry moat). The guide at Ōmiyabō accompanied me up. The paved path to the castle abruptly plummets over a cliff in one place, clearly damaged by a landslide.
