Japan has taken regard for visitors' hospitality and hygiene to the next level by introducing toilet paper for smartphones in lavatories at Narita International Airport. A second dispenser of toilet paper has been installed adjacent to the regular one in toilet cubicles at the Narita airport so people can use them to wipe their phone screens while answering the call of nature. These rolls of paper have been designed specifically for the purpose of cleaning smartphone screens. What is more, the wipes have a welcome message printed on them, along with information about Wi-Fi spots and helpful travel tips. An initiative by telecom giant NTT Docomo, the smartphone wipes dispensers have been installed in 86 stalls at seven restrooms in Narita's arrivals terminal. They will remain in place until March next year. The introduction of the smartphone sanitation system was in response to a research that showed smartphone screens typically carry five times more germs than toilet seats.
