Notes Access, from either Otsuki or Sarubashi (longer) station on the Chuo line.  (The thing to do would be to do a hike from Otsuki via Iwadonoyama down to the old bridge, which i didn`t, but it looks fantastic).  About 10 - 15 minutes to base of mountain.  Free information centre.  Very well kept trails.  Sigposting in japanese only but English hiking maps available. all text and photos by Kris
History 634 metres high, Iwadono Castle sits at the gateway to the country of Kai. It was also used for smoke-signalling and was a vital part of the effective Takeda communications network.  It was considered very strong because of its commanding views and massive unscalable bare rock face with only a few entry points.  In 1582, Takeda Katsuyori, escaping from Nobunaga`s forces, sought refuge at this castle but was denied entry by Oyamada, essentially making Katsuyori`s case hopeless.  Oyamada was later executed by the Oda, ostensibly for betraying his lord and being un-samurai-like.  Later taken over by the Tokugawa, this time to protect Edo/Musashi province.

    There is very little by the way of ruins even but if you are interested in hiking, or in the history of the Takeda clan, then this site is an easy day trip from Tokyo. There are lots of different hiking trails. The title picture is of the information centre at the base of the mountain - the staff were helpful and had good maps in Japanese and English. Their main theme when I went there was that both Iwadonoyama and Tokyo Sky Tree are the same height. I don`t know about Tokyo but the view from the Takeda Sky Tree is free and you have more chance of seeing Mt Fuji.
