One of the things the article touched on was how one Japanese costumer complained that other Japanese fans look at you funny if you wear a costume that isn't obviously a recreation of something. I've encountered that myself, and not just in Japan. Original costuming seems to throw some folks for a loop, but they're comfortable with you dressing as a character from something they already know.
On the other side of the same page was an article touching on our other hobby, trains, and someone building a miniature you-ride-em (looks like 15-inch gauge) railway.
