As a matter of fact, if you really are interested by onsen, I strongly would advise you to go out of Tokyo to enjoy a dip in a hot spring. There are destinations that are not too far from the capital and still really interesting: Nikko, Gunma-ken, Izu.
Still, this requires a day-trip, so it might be not attractive for everybody. If you really want to taste an onsen, then probably the Oedo Onsen in Odaiba might be the best choice: easy to access, and with a mixed rotenburo (for your feet only, though)...
