/jp/ - Otaku Culture

The japanese meaning of rape is actually more along the lines of forceful or aggressive sex. Hence why there can still be consent yet one of the parties claim to be raping the other.
The meaning changing a bit is common when there isn't a direct translation so the closest word is used. This is also why everyone in manga keep claiming ''I'll send you to hell'', ''I'll bring you there with me!'' even being or towards genuinely good people, as the equivalent ''Jigoku'' or Hell Realms are more in line with purgatory, a place you'd have to complete a sentence for your sins.
Likewise, the equivalent of god ''kami'' is more of divine and nature spirits. Which is why they have a closer, more down to earth view of them, to the point of possibly being gods of mundane stuff. Which is reflected in Zipangu with their mosnter girls being worshipped as such.
