Chikuma Osaka Castle
Located at an altitude of 990m and a relative height of 220m, Chikuma-Osakajō was a yamajiro fortification used by Osaka Village located on the plain below.
Chikuma-Osakajō was a nice little site to visit. I wasn't sure if I could find anything and so was pleasantly surprised that I was able to identify several features, including evidence of vernacular construction methods. The bulk of the ruins consist of the shukuruwa (main bailey) surrounded by dorui (earth-piled ramparts). The dorui reaches the whole away around the enclosure, being perforated by a koguchi (gate) ruin. It seemed that the path leading from the koguchi would go all the way down to Osaka Village, although I came from the mountain road via Ôike Village. Opposite the koguchi the dorui is tallest, still standing about two meters above the enclosure. At the back of the shukuruwa is a horikiri (trench cutting into the mountain's ridge line). I began climbing further up the mountain but couldn't find anything else apart from a depression on the ridgeline which might've represented a deformed trench ruin.
