Visitors laugh as they jokingly motion to give a push while sitting on colorful toilet bowls at the Unko Museum in Yokohama, south of Tokyo. In a country known for its cult of cute, even poop is not an exception. A pop-up exhibition at the Unko Museum in the port city of Yokohama is all about unko, a Japanese word for poop. The poop installations there get their cutest makeovers. They come in the shape of soft cream, or cupcake toppings.
