Sakasai Castle




Sakasai Castle was the easternmost frontier of the Hojo territory standing in opposition to the Satake, Yuki and other lords of the area. For the time period, it is a fairly large and tough castle that made use of the river and wetlands surrounding it as a natural defense. Sakasai Castle was abandoned after the Hojo were defeated by Toyotomi Hideyoshi in 1590.

Visit Notes

I've wanted to go to Sakasai Castle for a long time, but it is probably one of the most remote and difficult castles to get to in the Kanto area. I finally found a reasonable way to get there, but it still took all day just to go and come back because there was so much time riding or waiting for busses. Regardless, it was a great trip. They have done a fantastic job accurately rebuilding the structures here to reflect the feel of a castle from the Sengoku Period. Most castle reconstructions are based on later Edo Period castles, so this is a valuable site. Besides the reconstructions, the moats and castle layout are also well preserved with many signs. If you have a chance, please stop at the soba restaurant next to the castle. They have brochures for the castle and the people are incredibly nice. They called a cheaper taxi for me than the one I was planning to take and let me kill time in the restaurant on that hot day while waiting. Of course, I also had my fill of zaru soba before that too.

Cycling anticlockwise from Tokyo to niigata and down to Kyoto will allow me to pick up a few castles that I normally would not get to. This was one of those, combined with the cherry blossoms and preparations for hanami it took on a whole new look. Well worth the trip, just hope the rest I want to see will yield as good photo opportunities .

I now see that my first post was anonymous. I probably forgot to put my name. I agree Kris, this site is really worth seeing and the soba are really good :-)

I really liked this site. The grounds are nicely sign-posted and interesting to wander around and explore. The fact that you could climb a sengoku style watchtower was purely awesome. The curving moat was very Hojo-style; coming after heavy rains it was easy to see the defense value of the surrounding marshes. The pool where the princess drowned herself actually looked quite deep, dark and scary. Though there do seem to be some signs that they had planned to do more and ran out of money halfway it really shows that the town has pride in this site that they spent money reconstructing an out-of-the-way castle well rather than on, say, more of those expensive incomprehensible bronze artworks that litter Japan. For a castle that only existed for about 10 years and wasn`t such a major site this is truly worth seeing. I went by car and in the afternoon; the soba shop was closed which was a shame - it sounds good

An easy drive, and well worth the effort. The reconstruction has a great feel, and the view out over the valley from the yagura is tremendous. Walking the grounds and surrounding woods give a great perspective. Very interesting to see an earlier wooden style in lieu of the usual white stucco.

\ I don't know how the webmaster managed to pay only 2100yen for a ride at least the double of mine."As I said above you need to take a bus from Moriya Sta. There is a highway bus from there to a spot along the highway that is much closer to the castle. Bus schedules and routes seem to change around here a lot so email me for more information about how to get there."""
