Tokyo's Narita Airport is serious about toilet cleanliness. There is now "toilet paper" for smartphones in its toilets. Passengers can use the special paper to clean their phones. It is the idea of the Japanese phone company NTT. It paid for the paper to be put next to the regular toilet paper in toilets at the airport. Toilet seats are usually more hygienic than smartphones. There are five times more germs on a smartphone than on a toilet seat.
Japan is a world leader in high-tech toilet technology. Japanese homes have toilets with warm seats, automated bidets, and lids that automatically rise. There is also a gadget that produces loud flushing sounds that can hide embarrassing "toilet noises". NTT made a two-minute video to teach tourists how to use the smartphone toilet paper correctly. It also shows tourists how to use Japan's toilets so they "could enjoy their travel hygienically".
