KDDI lines up the first Japanese smartphone installed with Firefox OS.

Named the “Fx0,” the new model has a skeleton body to express the openness (i.e. unrestricted aspect) of Firefox OS. Artist Tokujin Yoshioka, responsible for the design, teams up with KDDI’s brand “au” for the third time, following the au design project “Media Skin” and au’s original product- iida “X-Ray.” Yoshioka’s latest contribution to au is a transparent design unveiling the beauty of the mechanics comprising the phone. The Firefox logo adorns the Home button of the device.

Before becoming freelance, Yoshioka worked under Shiro Kuramata and Issey Miyake and has marked his name as a designer who transcends the realms of product design and architecture to produce art. He has been handling the designs for Issey Miyake stores for over 20 years and has also handled the design of the Swarovski flagship store in Ginza, Tokyo. Many of his works are exhibited as part of the permanent collections of prestigious museums around the world including the MoMA, Musee d'Orsay, Centre Pompidou and Victoria and Albert Museum.
