In an email from Google I was told "Google AdSense is excited to announce the introduction of expanded language support for AdSense publishers. This expansion includes dedicated email support and account pages in French, German, Italian, Japanese, and Spanish. New applications for the AdSense program may be submitted in any of these five languages or in English, and AdSense ad code can be placed on pages with content in any of these languages, provided that those pages comply with our program policies and Terms and Conditions."
