While very little remains here of any part of the castle, it has great historical importance. In 1582, Toyotomi Hideyoshi defeated the ruling Mori Clan by diverting a river to flood the castle. The moat still exists, and is filled with lilies that bloom in the summer. You can also still see some of the old waterways. There is even a small museum with some artifacts and information on the site.

稲荷山健康センター
"Temporarily Closed" from 2020. Many of the baths here contain kampo (Chinese remedies), so they are supposed to have healing powers. In addition to the onsen, there is a home theater, game corner, manga corner, restaurants, chairs for relaxing, a souvenir shop and other facilities.
最上稲荷
Considered to be one of the Three Great Inari Shrines of Japan, Saijo Inari is a large shrine complex built on the side of Mount Ryuo. Legend has it that the shrine was commissioned by the priest Hoon-Daishi after prayers to Saijo (who came to him as a white fox in a dream) successfully cured two emperors of seemingly fatal illnesses. Buses run from outside the east exit of JR Okayama Station — disembark at 'Inariyama'.
造山古墳
Along the trail there are actually two burial mounds (古墳 kofun) with the name "Tsukuriyama" that can be distinguished only when viewing the characters used to write the names. The tomb on the Okayama side of the trail (造山古墳) is the most interesting. This burial mound, believed to have been completed in the fifth century, was the largest in the nation at the time it was built. Because the tomb within the mound has never been excavated, it is not certain who is actually buried here; however, it is believed to be one of the former rulers of the Kibi Kingdom, as tombs of this size were reserved only for those in the highest positions. Although the best view of Japanese burial mounds is always from above (to see the key-hole shape), at this mound, visitors are permitted to walk on top of it. Atop the mound there is a shrine.
鯉喰神社
If you walk the trail with no prior knowledge of the area or the sites, Koikui Shrine will seem quite disappointing in comparison to the other shrines. However, Koikui is much more interesting than it appears. After the demon was shot by the prince's arrows, he transformed into a carp and swam away. The prince turned into a cormorant and followed him. Koikui Shrine is located on the site where the prince is believed to have caught and killed the demon.
吉備津神社
Last rebuilt in 1425, this shrine is important for two reasons: it was once the head shrine of the entire Kibi Kingdom, and legend holds that Prince Kibitsuhiko-no-mikoto fought the demon Ura on this site. He shot arrows at the demon, but the demon evaded his attacks by throwing boulders at the arrows. Finally, the prince shot two arrows at the same time, hitting the demon directly in the eye (but not yet killing him - read on).
