The Nasu Trick Art Museum is a fun way to spend some time with friends or family if you are visiting Tochigi Prefecture. Different installations and artworks play tricks on your eyes and make for fun photos. Visitors are not only allowed to but strongly encouraged to bring cameras and actively play around in the various rooms of the three main buildings. A chair you cannot sit on... A painting whose women pours (actual?) milk... A mask that tracks your movements... There's lots to explore.
