Usually when McDonald's makes waves on the Japanese side of Twitter, it's due to exciting seasonal releases like savory rice or Mobile Suit Gundam burgers, but this time it's a restroom that has people talking.

Sho Sawada (@shao1555) recently shared a video taken in the restroom of a McDonald's they visited (as dangerous as that sounds, don't worry, it's clean!), because they were so taken aback by a system implemented at the sink. When Sawada went to wash their hands, they noticed an unusual thing slot right next to it, and upon reading instructions, was surprised by its purpose--

--to wash your phone!

"At McDonald's nowadays, not only do they have a place to wash your hands but one to wash your smartphone as well..."

Just Sawada's video shows, some McDonald's in Japan have installed sink systems that come with a slot that "washes" your smartphone. It's a system called WOSH developed by Japanese company WOTA. WOSH is a sustainable hand-washing stand that along with a reusable water based sink, uses a hydrological cycle system and deep ultraviolet lights to disinfect your smartphone. WOTA says that in just 30 seconds, WOTA offers 99.9% sterilization of your phone--which means you can wash your phone when you wash your hands.
