I'm very late to this thread, but that video impressed me! Distinctively Japanese but still very steampunk - which shows how flexible steam is. A bit of Wells, a bit of Miyazaki!
I strongly suggest visiting the other Japanese Steampunk thread (linked above). The only caveat is, that communication has been severed a bit. It was always a bit hard to get the Japanese folks to participate in this forum, and I did not feel a real "connection." Not to say that I felt we were "shunned" or anything like that, but I did feel a bit of a cold shoulder.
Their productions/events, are immense actually. They have an annual Steam Graden plus several other events during the year which include performance arts . You see, the Steampunk movement in Japan got started in the Tokyo nightclub scene and became supported by the craft art markets and DIY movement. They have benefited greatly from the Audio/Video production venues in Japan plus the very lively night life in the sophisticated Tokyo nighclubs, which have catapulted the movement into a very strong underground scene, which is much more closely related to the Goth and darker-themed crowds, and away from the bubble-gum Japanese pop culture on the surface.
For your reference, for a while I was acting as Brassgoggles' ambassador to Steampunk Mexico and the Tokyo Inventor's Society. The first one in Mexico, I was involved in from its inception, since I was raised in that country and I stumbled on the first Mexican movement which back then was brand new, becoming a member there. The Japanese forum, on the other hand, started one year later, and I fail to remember what led me to them, probably my meagre dealings on Twitter with the Japanese band Strange Artifact when I was promoting my Steampunk business in Japanese. I also became a member of one Spanish Steampunk group and initiated contacts over Facebook with Steampunk groups in Argentina and Chile.
In any event, a couple of years ago, communication between us (Brassgoggles, Tokyo, Mexico) became very scarce. The Mexican forum migrated to Facebook after fracturing from a single national forum into several smaller regional groups (there was infighting, and they were too big, you see, kind of like a Steampunk Supernova that exploded as it was too big to be stable).
Our contacts with the two national movements dwindled. Being beleaguered by real life issues, I failed to try to reinforce and cultivate the ties between the two forums and Brassgoggles, so my mission as ambassador didn't quite pan out as I desired.
