It's no mystery why these scans are coming from people living in Japan (well, the two of us, anyway.) We have the easiest, cheapest access to the mags.
But what's interesting is that all of these scans are being hosted by websites based outside of Japan. For me, well sure - I'm an American, even if I've been an expat for 9 years. But the other scanner is Japanese. Why not host them at a Japanese site?
Well, because there is no such site. There simply aren't any magazine preservation sites in Japan. The entire thing is seen as not only illegal, but unethical by the majority of Japanese (whereas I think it's safe to say that we here at RM may acknowledge the technical illegality of providing magazine scans, but have a far more lenient view on the ethical implications, so long as the mags being offered are old enough to meet our cut-off dates).
I recently was reading a thread on 2ch, a textboard that is probably Japan's largest and most influential online community (which ironically and fittingly, was founded by a Japanese while attending university in America). In it, users were discussing websites that offered high resolution scans of gaming mags. All sites referenced were foreign, and none were offering complete scans of entire magazines, just select pages. Also, to be fair, these were relatively new mags being discussed, not old stuff like we offer here.
The following is my translation of select comments.
As you can see, there were a couple of people OK with the idea, but most seemed appalled.
Btw, lest anyone think that the Japanese are as puritanically ethical regarding copyright as these posts might make it seem, I'd like to point out that in the years following the mass acceptance of CDR burners, countless shops in Japan opened up "CD rental" sections, allowing you to rent music CDs. And there, either right next to the CDs themselves, or else right by the check-out counter, spindles of blank CD-Rs were also being sold. But I'm sure the two had nothing to do with each other.
