Is there Public Hot Springs (Onsen) for both male/female in TOKYO? ? - tokyo male brazilian wax

I really want an onsen bath with my husband to enjoy Onsen in Tokyo. I know they are usually divided into male and female field. Is there a package to Tokyo? One of the advantages that only can afford, and do not bathe, and do not leave without accommodation in a Ryokan? We are in one months time. Is there someone you know? Thanks in advance!
