Going to Japan for the first time. Is it worth it to travel the 4 hours from Kyoto to Shirakawago? We were booked into Kyoto for 4 nights which seemed too much for folks not all that interested in temples, and I saw this was a World Heritage site; we thought we could split the Kyoto visit up and take one night to go further afield. 1) Can anyone advise as to how long a visit to Shirakawago might take once we are there, meaning, is it "worth" a whole day of visiting, or a few hours worth of sightseeing? 2) Also, how geographically spread out is it? Meaning-- is it walkable? Or do we need wheels? 3)Are there guides there that speak English, or is it do it yourself? 4) Finally can you book train reservations from Kyoto to Kanawaza from abroad and if so how? We are having trouble getting schedules and as we don't have much time, need to pin down the specifics to see if it is doable. Thanks!
