I've been looking for a nice one day hike to an onsen but had a bit of trouble finding good spots. I wouldnt mind hiking for a day, staying at the onsen and then hiking back the next day.
Extra points for nice mountain or sea views.
Im staying in tokyo for the majority of my trip but I'm happy to allocate a few days to the trip as well as rent a couple hotels on the way.
