Futako Tamagawa station is just one stop from Yoga - and the Seta Onsen seems to be between them both.
Map So it is probably the same one. (EDIT - Original Post has changed so Onsen is in differrent position now)
I should really emphasise that days where it would be clear enough to see Mount Fuji are the exception rather than the rule.
