The bus timetable has been updated in last two weeks, should have plenty of time to do it in a day if you get on at the closest station. Assuming you're properly prepared.
Only applicable for Yoshida and Fujinomiya.

My problem is I want to have a decent breakfast before I climb and everything is closed before first bus 6:30ish. My hotel breakfast starts 6:45 so I'm hoping they let me sneak in for a feed.
