I know PS2 consoles sold in Hong Kong and Taiwan can also play NTSC-J games, and they can also get some copies when the NTSC-J version of a game launches. For example, when Final Fantasy XII was released in Japan in March 16th, 2006, there were some copies that were released in Hong Kong and Taiwan also. It's just the packaging is a little different (the instruction manual is in Chinese, the box is in Chinese), and the game itself is in Japanese. I think the Japan sales figures already contained sales in HK and Taiwan. But for those regions where PAL tvs are used, they are better for the "Others" part. As in the case of South Korea and mainland China... they are NTSC-K and NTSC-C, respectively, so the sales figures in these two regions are counted seperately from Japan (if there's actually some agencies to count these figures at all...) I don't remember HK and Taiwan had a similar region code. If there's one then they should be counted seperately.
