Private onsen without staying for night (Kanazawa, Kawaguchi)

Hi,
next Max we are visiting Japan (Osaka, Kyoto, Kanazawa, Tokyo, Kawaguchi) and we would like to visit private onsen without staying for a night, if its possible in Kanazawa (We are staying near Kenrokuen) or Kawaguchi (near music forest museum). Also Kyoto would be an option.

I am trying to find something on the internet, but not sure if the are having right info on some webs.

Do You have any reccomendations?
Thanks
