Walking into Ken + Julia Yonetani's "Wishes" is like stepping into a bad dream. The room is illuminated by hanging chandeliers, their green light eerily flickering against black walls, as Disney's "It's a Small World" repeatedly plays in the background. This first Tokyo solo show for the husband-and-wife team Ken and Julia Yonetani is a visual comment on nuclear power that invites visitors to tread the fine line between fear and beauty.
