Speculations Will Mt. Fuji come into play?

[KiriNigiri]

We've now explored every major region/area of Wano apart from Mt. Fuji. Given the real world counterpart's landmark status and the historical significance, I don't see Oda passing up doing something with it.

Spoiler

Right now, Onigashima is hurling towards the Capital, which is stationed almost right at the base of the mountain. Mt. Fuji is notorious for its volcanic eruptions, so perhaps something chaotic occurs at the top to simulate that? Maybe that's where Luffy and Kaido's final fight takes place while the others work of a way to stop Onigashima's fall on the capital. Depending on how destructive Luffy and Kaido's fight is, the citizen's would be able to make out some of what is happening high above, especially if Kaido happens to be in Dragon form or some other similar large state.

I'd like to gather others' thoughts.

in the game, Onigashima have Volcanic area or something like that where in the manga we dont see any volcanic sign yet.

No joke, I actually was thinking that if Orochi survived, his only choice now is to try and destroy Wano to ruin Kaido's own plan. He might know how and it may play into Mt. Fuji erupting by some forced method.

I think mt Fuji is where the poneglyphs are created from the errupted element which is inscribed and then cooled down.
Seeing the similarities with Rodan, King may have something to do with it.

Mount Fuji is a potential ticking time bomb.
