Translations (JP to English)

[VoltaAsura]

I'm curious, what is Japanese grammar like? Are there sentences like English, and other European languages? Is there anything similar to punctuation, commas, periods, colons and such?

I know this question wasn't directed towards me, but go here http://en.wikipedia.org/wiki/Japanese_punctuation I hope that's what you're looking for. (in that article a period is referred to as a "fullstop".)

and also this was an interesting read (since I don't know Japanese either :P)
