Iōji-toride, also called Iōjiyama-jinsho, was the honjin (main fortified encampment) of Takeda Katsuyori during the Battle of Nagashino. Iōji-toride overlooked Nagashino Castle, and was used during the siege of the Tokugawa-held stronghold. The 'Battle of Nagashino' mostly refers to the skirmishes around the castle and the siege, whilst the famous ill-fated cavalry charge of the Takeda happened to the southwest at Shitaraǵahara.
Iōji-toride is a hilltop fort site in Nagashino Township, Shinshiro Municipality. Ruins feature earthworks, including trenches and baileys. There are three baileys: east, west and middle/main. Between the middle and east bailey is a dobashi (earthen bridge). There is a trench between the middle and west bailey. The main bailey, where Takeda Katsuyori encamped, has a reconstructed miyagura (watchtower), erected in 2010. Nagashino Castle can be seen from the fort.
Iōji-toride is also called Iōjiyama-jinsho, a jinsho being an encampment site, and specifically is known as the main encampment of Takeda Katsuyori during his siege of Nagashino Castle in 1575. The site is accessed via well maintained trails, and I took the one to the right of Iōji (Temple). It takes less than ten minutes to walk up.
