Tokyo has released a video of what an eruption might be like (Source):
Ashfall is the main threat, with maybe also lava flows for some areas close to the edifice.
Nothing appears to be pending at Fuji-san right now, and no alerts are up (overtourism is the main issue nowadays), but magma has been starting to move intermittently down there since the 2011 megaquake. I set up a post for it a while back, just in case; it has a few useful links.
Of note, though the references aren't in front of me right now, my understanding is that Fuji tends to erupt -- at least recently -- in tandem with Nankai Through megaquakes. This probably was a factor in the video's release, too, since they just renewed the warning that a big quake could happen at any time.
This does not mean that Fuji would go off, too, if a megaquake did occur. An eruption can happen whenever -- or not -- and this is just a possibility they're raising public awareness for. It's a cool video.
