Let's judge Japan by popular belief, assume that any Asian weird-going-ons are from Japan, and not China or Korea, and let's also judge them by weird festivals that may have been hosted once per thousand years as a joke. Let's also judge them on loveuality, because America has NONE of that. Judging them on cosplay is fun too, seeing as we do it too, see your nearest Anime Festival...
Japan itself isn't what this topic represents. I'm only showing what we find weird.
...That rant was posted before reading this, but I didn't type that for nothing. Japan finds us weird too, like how we eat burgers bigger than our stomachs when we aren't actually hungry, and how we get fat when we eat, see a side by side comparison of a champion american eater and a champion japanese eater.
