For the attention of the Japan Business Federation (Keidanren):

I have previously addressed Prime Minister Shinzo Abe in this forum about the necessity for Japan to internationalize further, especially by developing English skills. However, at the same time, I believe the world also needs to learn more Japanese.

Indeed, Japanese is likely spoken as a mother tongue by more people in the developed world than any other language except English. Why is it, then, that so few people in America and other developed countries are learning Japanese?
