Okayama Castle
noun
This is the same 岡山 that you learned with 岡山県. So what's Okayama castle? Yep, Okayama Castle!
When 城 is added to a place name like this, it takes the on'yomi. You haven't learned this yet, so here's a mnemonic to help you:
The lord of Okayama Castle is none other than Joe (じょう), your local farmhand friend. How a farmhand like Joe managed to become the lord of a Japanese castle is beyond even us, but it's Lord Joe to you now.
