It has recently come to my attention that there has been an event of some gravity held as of late in Tokyo:
Alternative fashion reporter La Carmina has recently covered a recent Steampunk event held in Tokyo Japan. Her blogpost can be found here:
Steam Garden: Tokyo, Japan steampunk party at Christon Cafe Shinjuku. Japanese cosplay fashion event.
The event was put together by a group called Tokyo Steam Garden. The group is comprised of Captain Kenny Creation, Philosopher Luke Chaos, Airship Technician Sa-Kyo, Medic Misa, Navigator Fiona, Princess Dani, Dolls, Green Fairy, Shisha and Boss the bird. They are also accompanied by Masters of Clockwork who sell various scientific gadgetry to patrons and supply Steam Garden with their various mechanical contraptions.
