I was wondering if it was something like that. I've seen lots of photos of the restaurants from friend's trips to Japan.The reason you see so much of this available in Japan is because Yakiniku, Korean style Barbeque, is extremely popular. That style of restaurant is around every corner, and Japanese camp style cooking tends to mimic this.
If you notice the camping cooking gear here in the US, mimics the household gear of the 50s and 60s. Some of the gear also holds to idealized views of what the old west cooking was like.
I personally grab the pots, pans, and utensils I use daily in the kitchen and take them when car camping.
