Yunishigawa Onsen

Hi, My planning staying 1 night at Yunishigawa Onsen and next day go Nikko .
So I have a few questions:
1. I can't choose between Nikko Pass all area and Yuttari Aizu Tobu Free Pass. Is Free pass the best option for my Travel.
2. I Can't find any bus time table from YunishigawaOnsen Station to Yunishigawa Onsen (If possible in English)

Hope to get some advice on what would be the best plan. Thanks so mush.

1) The Yuttari Aizu Tobu Free Pass won't pay off unless you are going to Aizu which I don't see on your list of destinations. The Nikko All Pass will likely be a good value if you also visit the Okunikko area, but it doesn't cover access to Yunishigawa. There is also teh Marugoto Kinugawa Free Pass (https://tabi.tobu.co.jp/ticket/honsen/a03_d.html) which covers access to Yunishigawa but not to Okunikko, so it could be a good value if you did not plan to visit the Okunikko region.

2) Departures from Yunishigawa Onsen Station:

Departures from Yunishigawa Onsen:

The bus ride takes about 25 minutes.

Uji Thank you for your help.
