Hi Ditza,
Welcome on our forums. Yamada Onsen area is a fantastic place to soak, and offers great opportunities year around.
I myself visited the onsen in Fukeikan in the middle of winter, when the waterfall was almost completely frozen! A great bath, definitively. Have you had the opportunity to stop in the nearby ryokan, like
Taki no Yu and
Goshiki no Yu? They also offer great baths in natural surroundings...
Thanks for sharing your trip's details with us! Hope to read from you soon again.
Here are some detailed information on Fukeikan:
Entrance fee : 500 yens
Bathing time from 11:00 to 15:00 (from 9:00 to 15:00, mixed bathing; the rest of the day, the outside bath is segregated and reserved only for people staying in the ryokan.)
