Also called Akayama Castle, Akayama Jin'ya was built by Ina Tadaharu in 1629. This castle was huge with several large baileys partitioned off by moats. The moats are only about 1-2 m deep today but originally they ranged from 4-6m deep! Including the samurai residences, it covered an area similar in size to what is contained by the main water moats of Osaka Castle (Honmaru and Nishinomaru areas) today. In 1792 Ina Tadataka was demoted for failing to rebuild after a natural disaster and the castle was abandoned.
The castle site is much bigger than expected and the moats are beautifully preserved and maintained. This is also one of the most extensively signposted castle ruins I've been too. The photos here only show a small representation of the informational signs on the site that talk about not only the castle but the Ina Clan and their contributions to waterways management. The site is mostly a park today but parts of it are occupied by various plant, flower and bonsai nurseries. Even on the site, the signs mix castle and jin'ya regularly. It seems that the books I have and websites tend to call it jin'ya more often so that is what I've gone with.
