I've found a rating system in some Japanese reviews that I like and I am going to try to adopt for future use, and I would like to see others adopt as well.
It is a 0-5 rating based on following categories:
Looks
Conversation
Sex
Service
Value for money
Overall
Just posted my first review based on this format. Added a few other elements I found helpful on the now defunct myredbook.com site.
Would be terrific if there was a review thread just for Yoshiwara. Also would be terrific if the review form data could be captured into a searchable database similar to myredbook. (For those of you not familiar with Redbook, it was focused primarily on the Bay Area of CA and was wildly popular for many years until taken down by the Puritans in the US gov a couple of years ago. It's the gold standard of review sites IMHO.)
