to travel from Mt Fuji (infact will stay at highland resort) to Nozawa.

"Highland resort"?
Will you stay near the amusement park Fuji-Q Highland?
Then, time required to get to Nozawa Onsen bus stop
is estimated at about 4 and a half to 5 and a half hours.

When will you travel?
(Timetables may be revised before the day of your trip.)
