Translation:How is it here?
-je at the end of a 'verb-constuction' should be translated as 'how'. (and inakuwa = it is)
steef368866 is right. Je - how ; hapa - here ; kuwa - to be ; na - present time ; i - it...And this everything in question form done. Ready !
I think it's more like "What's it like here?" "What's this place like?"
I don't know how these things work out in terms of what's idiomatic and what's not, but "What's happening here?" would be Nini inatokea/inatukia hapa?, I think.
