My daughter is heading to Gifu City early in January and will be living and working there until the end of March. She'll be busy during the week but have time to poke around on the weekends. She won't have a car, so she'll be reliant on public transport.
She lived in Japan for most of a year 6 years ago, so she's been to the various well known (and lesser known) sites all over Honshu, so the usual tourist spots are not high on her "to-do" list. Any suggestions of things to do and places to go?
