It often seems like the grass is greener on the other side. When it comes to Japan, it seems like the grass isn’t only greener, but it’s growing on a whole different planet. Japan is host to tons of new, exciting, weird, and even downright wacky different inventions. Some of them leave us envious, some we’d prefer to leave in Japan, and some of them leave us scratching our heads. Here are some of the coolest things to come out of Japan that will make you wonder why the whole world doesn’t use them yet.

State-of-the-art toilets
If you’ve got boys of a certain age, then you’ll know the scene in Disney’s Cars 2 where Mater (the loveable hick tow truck) travels to Japan and tries to use the bathroom. Presented with a confusing array of buttons he presses them all and gets the (clean) shock of his life.

Japanese toilets have a reputation for being highly engineered, but they probably leave the bathroom fresher than the rest of us, so maybe it’s something we should consider importing.
