It is weird that there is still no obvious comments about abundance of such objects in Japan (with fan community around them), or from even bigger “urban exploration” crowd.
Is it weird? HN's largest audience is American. The next largest is probably Europe. I'd be surprised if the percentage of Japanese users on HN was high enough to break into the single digit range.
Edit: My assumption seems close, Japan is at 1% based on this. I'm surprised.
