The Nagoya City Science Museum, being located in one of the busiest urban centers of Japan, gets most of its visitors arriving by public transportation. Without a car to store their stuff in, most of them are carrying some sort of bag with their personal belongings, plus, in the case of tourists from out of town, any souvenirs they’ve been buying while in the country’s fourth-largest city.
For those who don’t feel like lugging their things around inside the museum, there’s a bank of lockers. Of course, a drab wall of solid gray metal wouldn’t be very visually appealing. At many other tourist attractions in Japan, you’d see a brightly colored mural featuring some local mascot character, but the designers at the Science System went with something a lot more original and appropriate by plastering the chemical symbols of the elements on them.
