If you and your friend are looking for an advanced strip theater topic, you can try an amateur show. The one at DX Tohji in Kyoto runs 20 days per month and has been reviewed on this site. The amateur group girls are on average less attractive and less fit than the typical strip dancers, but there are many (paid) opportunities to kiss and touch the performers throughout the show, and some interesting activities on the stage.
The only other active amateur show I know is Honey Trap at Kurihashi Live Theater, about an hour’s train ride outside of Tokyo. They are performing now through the end of January. I went once a few years back and had a great time even with minimal Japanese capability. The local patrons were excited to have a foreign visitor at the venue and helped me navigate some of the interactions. The venue was rustic and the interactions with the girls were more tame than at Kyoto, but there were a couple of good dancers and all 8 performers were naked. It’s worth a Saturday afternoon train ride for a strip theater enthusiast.
