Hojo Ujiteru was one of the powerful lords of the Hojo family. He built this castle to strengthen the Hojo position in the area and help defend Odawara Castle from attack. After Odawara Castle was surrounded by Hideyoshi forces, Hojo Ujiteru, Hojo Ujimasa and Hojo Ujinao left to fight in Odawara leaving Hachioji Castle nearly defenseless. Soon after, the castle came under attack from Hideyoshi forces on June 23, 1590 and fell in one day. Hideyoshi later went on to defeat the Hojo at Odawara and complete the unification of Japan. It is said that Hideyoshi feared Ujiteru for his intelligence and prowess and that is a large part of why he demanded Ujiteru to commit suicide (seppuku) after he was captured.

Hachioji-jo was a great sprawling castle across the mountaintop with barricades built in strategic places to stall would be attackers or spies. The picture above of the entrance to what was originally the lord's palace. It is at the base of the mountain while the castle was actually at the top. There are a few small pieces of stone walls around the mountain but that is all that remains. The palace stood at the top of the hill across the bridge and was heavily fortified.

    I hiked to the honmaru of this castle this morning. After that i went to the Tsumenoshiro and even to the Fujimidai. The trail to these last 2 destinations is fairly difficult. You really need to watch your step. Since it rained a little bit today, i slipped several times and i fell once on my bottom, but no harm. To get to the site i took a bus at busstop #1 at the north exit of Takao station. I asked the busdriver if he went to the castle. Since it's a weekday i had to get off at Reienmae-Hachiôjijôato. The ride is 180¥. From there it's about 1.5 km to the guidance centre, where i got my 100 meijô stamp. On the trails after the honmaru i encountered nobody. At some times i thought i was no more on track, but then i saw a signpost. The site is very well signposted.(sometimes only in japanese).

    As of June 2016, the bus from Takao Station (platform 1) is bound for 八王子城跡. It lets off at a round-about where it returns to the station about 10 minutes later. The 100名城stamp is located inside the guidance center. Great castle site, it's very relaxing and the part up the slope to the 本丸跡 makes for a good hike.

    Nice grounds and ruins to walk around with interesting reconstructions of bridges and walls. Lots of interesting hiking and Buddhist monuments scattered through out the hills and grounds, making it a peaceful and satisfying journey.

    Hachioji castle was a defining moment for me in (getting lost) visiting castles. On Midori-no-Hi 2008 I went to Mt Takao. From the top of Takao I hiked down the Jitaki waterfall course. Then, following the outdated map a friend had lent me I went across the train tracks, up the next mountain and was lost for about four hours. At one stage I came across a crude map burnt into a picnic table. I finally found some ishigaki but the trail I had been following from the monument ended in tangled, impenetrable scrub. I scrambled back up to the monument - the sun was setting and I was starting to worry - when finally I burst out on to the strangest of things, a perfect green square of lawn surrounded by ruined, grey walls. It was at this point that I fell in love with ishigaki. There were giant stairs and a giant bridge and a giant stone moat – after wandering around in a forest then coming on this in the gathering twilight the effect was surreal. That is the way you should see Hachioji-joshi! I didn't get the 100meijo stamp but it looks like you can camp inside the castle grounds so I might go back if I find someone who will let me borrow their tent.

    Hojo Ujiteru fled to Odawara. His retainers put up a good defense against Maeda Toshiie, Uesugi Kagekatsu, Sanada Yukimura and others but the castle fell on June 23.

    This is definitely a nice place to do some hiking and enjoy the ruins. Noone has bothered to fix the English directions on how to get there on all the websites that I've seen. You need to catch the bus to Reinenmae bus stop, as the Hachioji joseki bus stop is no longer in use.
