Highest Frequency Words

Does anyone know of a list of Japanese words sorted by order of frequency? I know how to find such lists for English (for example), and just occured to me that maybe there are similar lists for Japanese. I was hoping for at least the top 2-3,000 words, but more is always better.

You can get the list of a kind you mentiond;

The govermental body runs this site.
On the site(http://www.nistep.go.jp/) you can find an e-mail address,
so I recommend you to ask a person in charge at this place.

Probably you can get the list at the following institution.
National Institute for Japanese Language and Linguistics

You click the link above. At the bottom of the home page
you can find "お問い合わせ," then press it.
Why don't you ask for the information you need there?
I think they can handle your inquiry in English.
