Does buying the pass make sense - 28700 yen

Also - Other consideration here is would it just be slightly more to not use the JR pass but be able to book the faster Nizomi train which is not included? this looks like it would save us some time traveling down to Osaka on the first one way there.

Hi there,

Looking at your itinerary I do think that a 7 day JR Pass could be useful for your travel. A return Tokyo - Osaka with the JR Pass as about the same price as the cost of a normal return by Shinkansen. Basically any additional travel you than make with the JR Pass is what you save. Such as travel from the Airport and between Tokyo and Kyoto.

When you travel to Fuji, the best way to get there is actually via Tokyo. Unless you plan to visit Hakone, in which case you can make a stop directly on route to Tokyo.

As you already know the Nozomi train is not covered by the JR Pass, however you can take the Hikari or Kodama instead, these trains travel the exact some route but make a couple more stops on the way and take a little more time. From the difference in time from Tokyo - Osaka is about 20 more minutes of train travel with the Hikari.

I hope this helps!
Daniel
