A few days ago, I was in the village of Ōyagyūchō and visited the Yagyuuyamaguchi Shrine on a hilly forested slope.
Yagyu Village (柳生の里) is located east side of Nara Prefecture. It is the home land of Yagyu clan and Yagyu Shinkage Ryu. There are many buildings and spots which are related with Yagyu clan, including their graves, the school, and ruins of houses.
The area was the former territory of the Yagyu clan, who became famous as the sword instructors to the Tokugawa Shogun with their famous school of Yagyū Shinkage ryū.
