Go can have zugzwang because passing can be a 'bad' move. Firstly, if the opposing player passes then you might be behind on points, or you could have to resume the game if counting isn't possible yet. Secondly, there are ko-rule-variants where passing can be a ko-threat or even where passing can be illegal. But zugzwang is exceedingly rare in go.
