Hachioji Castle – the prominent mountain Castle near Tokyo

Hachioji Castle was Built when Hideyoshi’s Punitive Force from West Japan Achieving East Japan


Hideyoshi was one of the most famous samurai leaders of Japan. His power was arising in west Japan and his army was proceeding to concur East Japan. Hojyo was, at the time, one of the most powerful clan leaders of East Japan needed to increase defensive force against Hideyoshi’s army. Hachioji Castle was built in Fukazawa mountain.

殿の逃走路A race glass vase (must had been imported from Europe) was found in a goten area (residential building). This is the only a race glass found in Japan in that time period. The master of the castle Hojo Ujiteru was leading a artistic and elegant life as if he was in a peaceful time.

Hideyoshi’s Hojo Subdude

The main branch of troops was attacking Odawara castle and his subsidiary troops came to attack Hachioji Castle. When the castle was attacked the master Ujiteru was away to Odawara and the castle was protected by minimum troops. The castle fell in one night. Hideyoshi ordered to kill everyone including women and children. Soon after the main castle Odawara fell and that was the end of Hojo. Ujiteru too ordered to Harakiri (honorable suicide).

御守殿の滝Waterfall of Gosyuden
Here is a waterfall outside of residential area. The legend says the women cut their throats and jumped into this fall when the castle fell… however you usually don’t jump into such a shallow fall nor cut their throats on top of it. In those days commonly survivors burn buildings and then cut throats when the castle fell. It is silly to think you can wonder off when there are full of enemy troops out side.

The castle was named after this shrine. The legend says, a renowned monk Myoko was in the mountain for a ascetic practice. While his training, he met a Gozutenno god and eight princes.
