The newest fashion accessory in Japan is a mouthpiece made of LED lights that you can program to make your mouth glow in a variety of colors when you smile.

The accessory gained popularity when used as a feature in the marketing campaign of LaForet Harajuku (whose blog we borrowed these cute pictures from) - a boutique in Harajuku (which some of you may know as the “fashion district” of  Tokyo that Gwen Stefani ripped off used as inspiration for her L.A.M.B. clothing line).

Inspired by LED throwies, creators Daito Manabe & Motoi Ishibashi decided to show off their newest creation by outfitting them on young Japanese women and parading those women around the streets of Tokyo.  Which, incidentally, is how I feel all new technology should be unveiled.

It’s just weird and techy enough to be a huge hit in Japan. Will it migrate West?  Well, we did sport Silly Bandz, so why not this?  It’s not as bad as some other popular Japanese fashion trends.
