Great place for couples, families as there are lots to do and see. Would have been nice if the cherry blossoms were in bloom while we were there. Otherwise easy location to find.
Took my infant son to Omiya park (walked there from Omiya station) in February. He loved the playground and the small zoo there, and we happily killed half a day there. Well worth a look, as it's rather scenic. There's a shrine in the grounds too.
