Behold, a coat. That will hug you. And whisper into your ear. Some Japanese students at the University of Tsukuba decided they'd put their effort into creating a coat that could give the sensation of being hugged from behind by their girlfriend. Make that, their imaginary anime-sounding girlfriend.
The result is called the Riajyuu Coat. The Japanese slang "riajyuu" means someone who is pleased with their life outside the internet. It's a mashup of the words "riaru", which is the loan word for "real", and "jyuujitsu", which can mean "satisfactory" or "complete".
The above video recently showed up on Japanese site NicoNico Douga. It seems somewhat tongue-in-cheek and not entirely serious!
Among university students and researchers in Japan, there appear to a handful of them who enjoy creating devices and machines that serve no real purpose, such as last year's robot butt. Well, maybe these things do have a purpose...
