That's not what I was pointing to. Check the visa requirements for various visas for the US, Japan and other developed countries. They follow similar thought patterns: skilled workers with demonstrated experience and/or knowledge, who won't be a burden on the state. The biggest boon being most skilled workers from developed countries already know English at an okay level, and most developed countries accommodate non-native language speakers better than Japan does when it comes to immigration.
