Localization in Japan and China 

While localization often involves common challenges across all languages and international markets, localizing into Asian markets can be particularly challenging for a number of reasons. The most obvious challenge for many of us is understanding the language itself. Multi-byte character sets and different levels of formality tend to make these projects a bit more complex. They often require more time, slower translation time, and more thorough review and quality assurance.
