Notes This castle is just a short train ride from Shinjuku. If you are a castle fan in the Tokyo area, it is a must see. The pictures really don't do it justice. Even though there are no original buildings, the basic layout and structure of the castle is mostly intact. It's a fun place to explore with many moats and earthen embankments. You can pick up a map at the entrance or in the Nakanomaru bailey but only the 2 main roads are marked. Make it day trip and visit nearby Hachioji Castle too.
History In 1521, Oishi Sadashige moved his castle here from nearby Takatsuki Castle. The power of the Oishi waned and this area came under the control of the Hojo in 1559 when Oishi Sadahisa adopted Hojo Ujiyasu's son Ujiteru. Ujiteru greatly expanded and fortified the castle into the best mountaintop castle in the Kanto region. After turning back difficult attacks by both Uesugi Kenshin and Takeda Shingen, Ujiteru moved his castle to what is now called Hachioij Castle. This was a stronger location and better built castle.

    Takiyama castle has possibly the best maps ever for remnant earthwork. There is the usual topographical map overlaid with the locations of castle structures, but next to that they have sketched a close up of the current location, and then a corner box of little ashigaru fighting, showing how the structures would have been used in defensive operation. My favourite was the ni-no-maru, which had the Takeda troops in red battling it out against the blue-clad Hojo poking spears through the fence and firing down a rain of arrows. The fact that the Takeda forces made it as far as the ni-no-maru in what was considered to be one of the famously difficult to attack mountaintop castles of the time was the spur that lead to the construction of Hachioji castle. I agree completely, this is a beautiful site to visit and a lot of fun to wander around.

    We visited this castle in combination with Hachioji castle and Jindaiji castle in Chofu. Similar to Hachioji with grounds and moats to explore but less features or atmosphere.
