世論 What Japan Thinks
A recent survey from the What Japan Thinks blog web site concluded that most Japanese thought that it is cool to speak English. Not exactly scientific with only 430 polled. The results also showed that Asian languages were rated much lower than Western ones.
What Japan Thinks was created by Scottish blogger Ken Yasumoto-Nicolson, who translates Japanese opinion polls and surveys from kimonos to keitai (cell phones).
