Think of it more as embracing one's heritage and trying to maintain a cultural identity.
I'll believe that when I hear it from a Japanese person. But I doubt I would. As I said, Japanese culture is as much about embracing modernity as valuing heritage. Real Japanese people don't go around waving swords and knives all the time; they're far too busy with their mobile phones and other gadgets. Surely to Japanese people centuries in the future, their cultural heritage would be as much about bullet trains and anime as about kimonos and swords.
