My mate and I figured: we're guys, we are in Japan and people didn't seem to care or be objective or judgmental of the sex shops one way or the other - so we wandered into one or two...or three...maybe five. Okay, six! It truly was surreal. There were other men wandering around in the shops with shopping baskets like they were swaggin' down an aisle of Family mart! Begging the question how much porn do some buy in one go!? I guess buying in bulk saves trips. It was funny watching other men mooch around like they were in HMV. Shop attendants aren't as helpful as they are in HMV though. These stores are all about anonymity. The store attendants only acknowledge you if you approach them. Fair do's! I guess no dude wants a store attendant creeping up behind him yelling "Welcome!! What kind of DVD are you looking for!? We have a buy one get one free on guzzling and bestiality today!" A couple of the stores have till points where a piece of non-transparent piece plexiglass or a curtain is placed between the cashier and the buyer, so the transactions were faceless. Again; adding to the anonymity and killing alibi's in cases where a husband is buying porn when he shouldn't.
Sex is a weird thing in Japan. It's still a bit of a taboo subject, yet it isn't at the same time.
