Is it Possible to Visit from Osaka to Nabano Sato at night?

Hi there,

I plan to visit japan next week with draft itinerary (still unfinished) as below :

Day 1 : Tokyo (only around shinjuku, harajuku, ginza, etc)
Day 2 : Tokyo - Kawasaki (Doraemon Museum, Sensoju Temple, Hananomai Ryokoku Kokugikanmae )
Day 3 : Yamanouchi (Monkey Park)
Day 4 : Tokyo (Mt. Fuji, Lake Yamanaka, Onsen, Gotemba FO)
Day 5 : Heading Osaka (spend night in Osaka), Nabano Sato ?
Day 6 : Osaka & Kyoto (fushimi inari & Otagi Nrnbutsu-ji)
Day 7 : Osaka & Heading Tokyo
Day 8 : Tokyo (owl cafe, etc..)

This is my 3rd visit to japan, but my 1st time using JR Pass. I am not sure whether some destination on my itinerary will be covered by JR Pass, so my questions some of my questions are :

1. Is it possible to use JR Pass to visit Monkey Park at Yamanouchi Town?
2. Is it possible to use JR Pass for trip to Mount Fuji area and Gotemba ?
3. If I have a plan to visit Nabano Sato at night (during my stay in Osaka), is it possible to use JR Pass to get back to Osaka at night? (let say, i will finish my trip in Nabano Sato around 8 or 9 PM.)

Many thanks for your help! :)

warm regards,
Ayu
