This is the coolest thing I've seen all week! It must've been so much work rehearsing and setting this all up, with all the little details, like the furries driving cars in the background :3
I was more impressed it seemed like it could have been one take for the final video, I only saw one or two spots where there could have been a transition. I just wish I understood Japanese. I didn't notice the cars the first time.
I especially wonder how the final shot is done, lifting into the air. I assume it would be a boom camera, but I didn't see ant boom in the shot, so I wonder how that was done.
For anyone curious on how this sort of video is made, OK GO has a great behind the scenes for "I Won't Let You Down". The biggest "trick" is recording the video at a different speed than it's played at. It gives everyone just slightly more time to hit their poses and still have it look crisp in the end result.
"Fursuiter" is a fairly old term, relatively speaking. Wiktionary lists two examples from 2009 and 2010, but I'm sure the term is way older than that. There's an Urban Dictionary entry from 2003, for example. The Wikipedia article about fursuits says that the term "fursuit" is "believed to have been coined in 1993 by Robert King," and adding the -er to it to describe someone wearing one feels natural enough for it to have happened soon after that.
