When it comes to hygiene and cleanliness – Japanese airports have taken matters up a notch by introducing “toilet paper” specifically for smartphones.

According to The Guardian, if you find yourself at Narita International Airport, you will be pleasantly surprised to find a toilet paper dispenser next to your regular toilet roll. But because of its miniature size, people might wonder what it’s for. Well, it’s to give your phone screen a germ-busting wipe. Considering that 1 in 6 cell phones are contaminated with fecal matter, this isn’t a bad idea.

NTT Docomo, Japan’s largest mobile phone operator, is the company responsible for this unique concept. These dispensers have been put in 86 toilet cubicles inside Narita Airport and will remain there until March 2017, reports The Telegraph.

This introduction to mobile screen cleaning papers is a response to a study that found out that smartphone screens have more germs compared to a toilet seat. Another survey showed that foreign visitors are generally impressed with the cleanliness and usability of Japan’s toilets. These factors further reinforced Docomo’s idea to introduce these smartphone sheets which also bear welcome messages for visitors and an instruction on how to connect to Docomo’s Wi-Fi service.

Toilets are considered serious business in Japan where many public buildings are fitted with modern and high-tech washlets, heated seats, and jets of warm water.

In some toilets meant for the ladies, there’s even a “sound princess”, a gadget that produces loud flushing sounds to cover up any embarrassing noises produced when a woman answers a call of nature.

Truly, Japan’s toilet game is on point.
