I think it says おとせ (otose), probably スピードおとせ as in "lower your speed". Anyway the car number plates and clusterfuck of powerlines are undeniably Japan. In saying that, the overall vibe does feel very much like Australia.

But am I the only one that thinks this was AI generated from real photos with maybe some editing added on after?

Sorry OP, if you really did do this all by yourself, please take it as a compliment, but I'm just not convinced.
