Where did you get the idea from Clockwork from? I googled Karakuri and I got something from One Piece and that had something to do with robots etc. But this castle in Goemon is just an old-fashioned Japanese castle.
Aha. Okay, no big deal. Karakuri is, in my experience, frequently in reference to some type of mechanism. The context in which I've most often seen it is Samurai Shodown, which takes place roughly in the same time period of Goemon, doesn't it? In both instances, two separate characters: Yagyu Karakuri Hanma and Karakuri Ocha-Maro both are made of/make use of (respectively) wood and metal machinery, gears, etc. So, it's the first thing my mind goes to, rather than "trick."
Well, it's got a maze in it and Goemon ends up getting "tricked" in the end.
Hah. Well, in that case, I'd be tempted to translate it, just to retain the obviousness of the joke.
That font for Akira certainly looks similar, but it's not quite the same as the BEast Buster font.
Cool. I was just curious. I've always liked that font.
