Norwegian, naturally since I'm from Norway.
English (duh...)
Danish and Swedish. Well somewhat. I can understand it well unless it's a hard dialect, then some concentration is needed. Speaking would sound horrible, but I could do it. Reading Danish is no problem since it's close to Norwegian. Reading Swedish is a bit trickier, but I had to use a couple Swedish books for my education and that went well. So I can read Swedish, but I would prefer Danish if Norwegian or English were unavailable.
Teeny, tiny amounts of Japanese, thanks to anime/manga.
