Notes 山上の見事な石垣にとても感動しました。私が行った数日前に草木を刈ったばかりなのでなおさらきれいに見えたと思います。兵庫県では竹田城の次に、全国で見ても最も石垣が立派な山城の一つです。登山道は結構急で足場が悪い所もあるのでいい靴と履いて時間を十分にとってください。トレッキングポールがあれば持って行った方がいいと思います。登りが大丈夫でも下りはちょっと不安です。山頂からの眺望もすばらしいので山に登る価値はあります。
History Yamana Suketoyo built this castle in 1574 after his Konosumiyama Castle was defeated by Hideyoshi. Arikoyama Castle is just Xkm south of Konosumi Castle. Another name Konosumi Castle is Konusumiyama (盗山城) which looks like "stolen child". He named Arikoyama Castle (有子山城) "mountain where the child is" as a play on words from Konusumiyama. Arikoyama Castle was again attacked by Hideyoshi in 1580 when Seketoyo's son Akihiro was lord of the castle. After it fell to Hideyoshi, Maeno Nagayasu and then Koide Yoshimasa becams lords of Arikoyama Castle. Afer the Battle of Sekigahara, Koide fortified the foot of the mountain as Izushi Castle and abandoned the mountaintop Arikoyama Castle. After hiking up the mountain to get to the castle I can see why he wouldn't want to use it if it was no longer necessary. The Edo Period saw a more stable government with no local conflicts so many provinces moved from mountaintop castles to lower castles and put their efforts into building up the surrounding castle towns.
