Obama Textbooks in Japan

I saw a very interesting piece on the news yesterday. Apparently, Amazon.com's number one selling book in Japan is a book of speeches by President Barack Obama. These speeches were made famous in his campaign and the are now being used in Japan's classrooms in middle and high school. The students are using his speeches as an example of how they can become better speakers. They are also used for an english textbook, teaching students proper grammar, etc. These books go for about 12 dollars a student. Also, a book with his inagural address is a big hit. Here is a link that briefly explains this story. I saw it on one of the 24-hour news networks but can't remmeber which one. This is a good enough link from Yahoo news that has the story....
