Not sure where you mean (top of Madarao)?Has anyone ever done a bus run from top of madarao all the way down to iiyama ? Is this even possible without a hiking to much ?
From Madarao Kogen Hotel is where they leave from.......takes you to Iiyama station.
If you want to do some supermarket shopping, there is a supermarket next to Iiyama station.
Here is the timetable. Easy.
