Koromo Castle of Koromo Domain was built in 1749 by Naitō Masamitsu. Formerly the territory had been administered by the Miyake Clan from their Jin’ya, known as the Sakura Residence because its founder, Miyake Yasusada, had planted cherry trees all around it in 1600. Jin’ya were smaller scale administrative centers built in fiefdoms too small to support a castle. Koromojō when originally built had two yagura and a small donjon. It was also called Shichishūjō (“Seven Country Castle”) because from the castle could be seen seven provinces: Mikawa, Owari, Mino, Shinano, Tōtōmi, Ise, Ōmi.
Koromo Castle consists of an ishigaki (stone-piled wall) segment with a turret atop. The stone blocks used in the rampart segment show signs of being quarried and carved traditionally, which makes me think that the yaguradai is preserved from the Edo Period, or perhaps later restored using original materials. It is next to a modern stone wall, however. The turret is not original and was reconstructed in 1978 (English Wikipedia says “1959”, which I think is a mistake, and Japanese Wikipedia says 1977; I’m using 1978 because that’s what the sign at the site says). Now part of a park, the site is quite small, although the original castle was more expansive. A depiction of the original castle is shown at the site. The yagura was not open when we visited. Next to the castle is a large tea pavilion called Yūjitsutei which was originally built as a sho’in and chashitsu at Terabejō (long lost go’ten remnant perhaps? Although Terabejō became a jin’ya in 1618), but was relocated to a temple, Ryūju’in, in 1892 before being acquired by Toyota City in 1977.
