Akiu Onsen Day Trip

Hi,

I�fm in Sendai with my girlfriend. We would like to make a day trip in Akiu Onsen. Are there mixed onsen and or private? If so, is it possible to book?
If not exist there alternatives around Sendai?

Thanks.

The default is public and separate at any onsen.

I could not find special notes for these 14 places at Akiu Onsen, but there would be some.
