Hello, thanks for the test! Although it looks better than the first one, to be honest, it is still completely unsuitable for Japanese (if you want to have a “real” map): It is clearly a Chinese font, which is really different in some characters than a Japanese person would expect. This is also true for Taiwan, which is a little bit different. Korea also uses different characters, but because Korean usually uses Hangul, this is not so much of a problem.
Therefore the only solution would be to render Japanese text (either the name:ja tag everywhere or the name tag in Japan) with a Japanese font. In essence, use 4 fonts (Chinese mainland, this can be the current one, Japanese, Taiwanese, Korean) and select them based on the language and area. But the problem for East Asia in OSM does not only lie in the fonts: The entire OSM rendering is completely European centered. For Japan (and the other east Asian countries; I guess also for other regions like India, Middle East etc) being usuable in OSM, the entire rendering for this countries should be rewritten from scratch. For example, in Japan and Korea the street crossings have names, in contrast to the street. The houses are arranged in house blocks and city blocks, which have to be shown. Also, for example, buddhist temples show a 卍 on the map, hot springs show a ♨. Some shops should be much more prominently displayed (for example the ubiquitious convenience stores) etc. I am not well versed with other regions of the world, but I guess they have similar problems. Keeping all that in mind, at some point I come to the conclusion that the only real possibilty for OSM to be used in these countries is to let the different countries create their own tile servers. They know best what should be displayed and until OSM does not offer a way to incorporate these changes on the main map (which is nonetheless the best way and a method for that should be persued, I think!), OSM in this countries will not be used in any way. As to your original question (Sorry for the long off topic text): Actually I cannot see much of a difference. The problems making it rather unreadable are the followings: 1. The fonts are too small: This works for latin text, and would work for CJK text if used on a higher resolution screen, but for currently used computer screens (and the rendering in the tiles), it is too small. Well, I am not a native CJK speaker, so this might be different for other people, but for me, it is too small and unreadlable. 2. Connected to the first issue: The hinting and anti-aliasing of the characters is bad. If you have such a small rendering of the font, rather use a nicely hinted bitmap font. I have created a comparision of this issue: First MS Mincho 11 pt with a 70% zoom in MS Word (where bitmap fonts are used), second MS Mincho with 11 pt and 200% zoom (no bitmap fonts at this zoom), afterwards shrinking it to 35%. Admitely, rather a bad method, but you can clearly see the difference. http://abload.de/img/comparisonidqpu.png 3. The white shadow makes it at some points even more difficult, but I cannot say that for sure. This is connected to the Chinese characters, Korean works relatively fine I guess (although I don't speak Korean). By the way, there is also a DroidSansJapanese font with Japanese characters.
