One thing that you could see in Japan and not in other country?
18+ content items sitting on the shelve in the normal store like it’s a normal item, In place like Akihabara they also have advertisement of Adult video game on the street.
There is this one big store where we visited that had a lots of comic and game and other toys lining up, then there is a section for adult content item but they don’t separate it from other section!
I know that Japan is pretty open to thing like this and they are big on censoring but it seem like they did not even hide these thing from kids since you can see it pretty much everywhere if you just pay attention to your surrounding.
And if you haven’t notice even the Television in our hotel have porn channel, although you have to paid to access it, you can still watch their “preview” for free about a minute so anyone even a 5 years old kid might accidentally hit the button and see it. Japan is pretty convenient in accessibility to everything but maybe they should reconsider some of them…
