Is there a bus from Magome in Gifu prefecture to Komagane in Nagano prefecture? If yes, please provide information on schedule and if I need to reserve.
The Ina-Nagoya line bus has stops at Magome and the Komagane Bus Terminal. You can see timetables and make reservations on the Highwaybus.com Ina-Nagoya line page.
I hope that answers your question.
How can we travel from Magome town to Magome highway-bus stop?
Is there a luggage storage at Suganodai Bus center or at the Komagane Bus Terminal?
The Magome bus stop is at the bottom of Magome-juku. You can see it in Google Maps here.
Regarding luggage storage, there are coin lockers at Suganodai Bus Center. If you plan to take the Chuo Alps/Komagatake Ropeway, there are also coin lockers at the starting station, Shirabidaira. The coin lockers cost 500 yen per day and can fit one large hiking pack or several carry-on items. If you have large suitcases, then you can inquire with staff at Shirabidaira Station about storing them.
I hope that helps answer your questions!
