As a solo foreign traveler with very little Japanese language ability, I participated in the event with the mindset of enjoying a performance, and it was very fun. I recommend going with companions for even more enjoyment. Knowing Japanese would allow for better interaction with the dancers and hosts. However, even without Japanese, there's no need to worry, you can still enjoy a great show and service.
If you want to watch a sexy show, this is a very good choice. If I get the chance, I’ll visit again.
