The Hiraga Clan Castle Site (平賀氏城跡 Hiraga-shi-jō seki) is located in Saku City, Nagano Prefecture. It was the residence of the local lord of the Saku district. At the end of the 12th century, Minamoto Moriyoshi, a son of Minamoto no Yoshimitsu (源義光, 1045-1127), became the lord of Hiraga Village and changed his name to Hiraga Moriyoshi (平賀盛義). However, in the Jōkyū Rebellion ( (承久の乱 jōkyū no ran) of 1221, the Hiraga clan took the side of the retired Emperor Go-Toba (後鳥羽上皇) and was defeated. Afterwards, other local clan seemed to have taken the name Hiraga. Also, Hiraga Gennai, a famous scholar and inventor in the middle of the Edo era, was a descendant of the Hiraga.

① The good thing was that I came across many enclosures on the backside of the mountain. The whole mountain - though not that tall - had been turned into a fortress.
Below the stone wall of the third enclosure (三の丸 sannomaru).
② Arriving at the sannomaru.
③ After more climbing, I reached the inner bailey (本丸 honmaru).
This was another enclosure situated on the backside.

Visiting the castle site
I tried to climb the castle site from the northern side and parked my car on the parking lot of Saku Hōju Cemetery. However, I failed as I was unable to locate the path to the castle. And while there were no signboards, I managed to reach the top of the mountain but got completely lost on my way back.The map is based on GSI Map powered by the Geospatial Information Authority of Japan.
