Tokyo's Narita International Airport has taken toilet cleanliness to a new level. There is now "toilet paper" for smartphones in the public lavatories. Passengers are encouraged to use the special wipes to disinfect their mobile phones. It is the idea of the Japanese mobile phone giant NTT Docomo. It also paid for the wipes to be put next to the regular toilet paper holder in 86 cubicles at the airport. An NTT YouTube video said toilet seats are usually more hygienic than smartphones. It said: "There are more than five times the germs on a smartphone screen as compared to a toilet seat."
Japan is a world leader in toilet technology. It has the most high-tech toilets in the world. Many Japanese homes have toilets that have innovative flushing, warm seats, automated bidets, and lids that automatically rise when you enter the toilet. There is also a gadget that produces loud flushing sounds to hide embarrassing "toilet noises". NTT made a two-minute instructional video for tourists on how to use the smartphone toilet paper correctly. It also shows how to use Japan's toilets. NTT said it wanted to make sure, "foreign tourists could enjoy their travel hygienically".
