Fuji Hakone Free Pass and Mishima

Hi all, I have a query and will be thankful for any responses here!

I will be travelling to Numazu in June and am thinking of getting the Fuji-Hakone pass (from Mishima Station) to visit Hakone and Lake Kawaguchiko during my 2 days in the area. My travelling during these 2 days will be as such (Do note that i will be using my JR Pass as well).

Day 1 - Numazu - Mishima - Odawara - Hakone. For the return trip, i am planning to use the pass to get myself to Moto-Hakone before taking the Tokai Bus back to Mishima to end off the round trip. That means i do not intend to pass by Odawara on the way back to my lodging.

Day 2 - Numazu - Gotemba - Lake Kawaguchiko. Return trip will be in the reverse order.

Will the travelling trips for the above be covered fully by my JR Pass and Fuji Hakone Pass? If anyone here has a more efficient way for me to travel to and fro mishima and Lake Kawaguchiko/Hakone, please let me know, thank you!

You can't purchase FH-Pass at Numazu also Mishima.

Read again, "Fares and service guide"and "Where to buy".

If you purchase at Shinjuku station or Odawara station in advance, you can use from Mishima.
And, this pass won't be sold out(sales numbers is no limited),
so maybe you have enough time to go to Odawara on the day first, if you don't oversleep.
You can specify the start date of use, no worry. (date stamp is so)

If you will get(or got) a lot by Japan Rail Pass on other days,
it is no problem even if you take Shinkansen to Odawara on that day.

Also you can ask about only FH-Pass by e-mail.
