Hello Jocelyn!
I believe it is best to do Tokyo > Hakone > fuji > Osaka.
From Hakone youll have a great view from Mt Fuji before you actually go there. Also, Hakone is on the way to Mt Fuji so the itinerary makes more sense.
Have you taken a look at the itinerary pages here in Planetyze?

I hope this helps!
Have fun!
