Izu Ohdairashin Castle
After the fall of the Imagawa Clan, the Takeda Clan and Hōjō Clan fought fiercely over the provinces of Suruga and Izu. The Hōjō built a number of fortifications in Izu and had their clansmen and chief retainers defend them. Ôdairashinjō was one such fort built as a link between Nirayamajō (see: Nirayama Castle) and Tokurajō. Ôdairashinjō was a strategically useful castle in controlling the Kano River and even Shigesu Port. Tôyama Tamibe was castellan of Ôdairashinjō. However, Hōjō Ujimitsu took over command after the Takeda Clan seized Tokurajō.
Ôdairashinjō ("Great Plateau New Castle"), is also called Minamimiyajō ("South Shrine Castle"). It is located above the temple Engyōji, near to the nationally designated historic site of the Kitaema Grottoes. The main bailey is cleared. Sub-baileys form a nice profile when viewed from below and are now the temple's necropolis. If one climbs the mountain up past the Karakasamatsu-tōge ("Paper and Bamboo Umbrella Pine Pass"), then one will come to Ôdairakojō ("Great Plateau Old Castle"), but it was already getting dark when I visited and so I didn't have time for that. As I said, the profile of the ridgeline looks like the castle's footprint likely extended further down into what is now the temple's necropolis, and there is a separate smaller spur of terraced sub-baileys which climb the ridge up from the temple's other side where there is a torii and small shrine.
