An object depicted in a painting may appear to be 3D depending on how it is painted. The angle from which an object is viewed may alter the observer's perception of it. Such optical illusions are known in Japan as trick art, a term coined by SD Corp., an art production company based in Nasu, Tochigi Prefecture. The pioneering company is behind the Tokyo Trick Art Museum in Tokyo's Daiba district.
The museum features depictions of Edo-period (1603-1867) tea houses and post towns. I saw one visitor flipping a tatami mat with her bare hands; another was spinning a huge tub with his legs like a hamster -- or so it seemed.
"I can't help but be excited. I feel like I'm a child again," said Yoko Sato, a 58-year-old housewife from Hamamatsu who was visiting the museum with her friends.

Toby Erthle, 35, a tourist from Munich, Germany, said, "Japanese trick art is also famous in my home country. Simple though it might seem, the abundance of ideas here is amazing."
The key appeal of the museum is that it encourages not only viewing but also touching and taking photos.
Optical illusions can be appreciated and shared with friends and family. "If visitors have richer communication than usual through the exhibits, we have achieved what we were aiming for," said Hironobu Shimizu, 45, the director of the museum.

Some exhibits utilize augmented reality (AR) technology. For example, some of the paintings hanging in the museum come alive when viewed using a dedicated smartphone app. Visitors can immerse themselves in the exhibits by using the AR app, with which users can make it seem as if they have become mermaids swimming with fish, or have joined a couple dancing.
The museum features 54 exhibits that can be enjoyed by adults and children alike.
