I was just thinking about negation by adding the suffix. We have it in Bangla too. In fact, we share the same word, 'nai', for 'is not there'.

I think many Indian languages have it too.

And in fact the Japanese negation at the end - negation suffix ("nai"→"naka") - from whym's comment in this thread - sounds like the Marathi one - same sound (naka or nako).
