Oh...so it's basically The Skull Man.

No, Skullman is completely different from Shin. It's kind of an insult to even compare them.

But...wasn't Skull Man what Ishinomori originally intended, but Toei requested he change it to a bug theme to be more kid friendly?

I've been thinking. There is so much in KR you could never get away with on American television. Before you even get to the cuss words. Cops dying, people dying, the mature subject matter of the dialogue and plots.

Though some part of me does hope, one day, some how, we get Hibiki as an import.

I assumed the swearing was always like poetic license for subbers. They obviously know the audience/downloader is going to be older than the original intended market so why not make it a bit more edgy and real. That or it's a Japanese idiom that does roughly mean that 'swear word'

No, it's the word. Japan is more liberal than America, remember.

Hmmm , maybe. I'm going to have dig into this issue at some point for my dissertation anyway. But it can't just be that the Japanese let their kids run around calling each other bastards.

No one's saying that. But Japanese television can get away with aaaaaaaaaaaaaaaaalot more than we can.

Definitely, through all of the strict social norms and conservatism.

There's nothing wrong with the words.
You have to remember, there is no almighty Webster going around telling other countries that certain words are taboo.
The connotations of a word here doesn't hold the same weight in Japan. There it's just a word. It's not Japan being lax, it's just our culture assuming that curse words here are curse words there, too.
It's kinda like a Jamaican assuming bumbaclot is a curse word everywhere.

Basically: Curse words aren't universal or multilingual things.
