The same problem for me.
I posted my solution on https://www.ads-software.com/support/topic/344708?replies=7#post-1354001
But the solution is basically the same as Mr. koitaki’s one.

Same problem for me, too. I’ve solved the problem by doing this.

1. Delete wp-includes/pomo/translations.php
2. Place new translations.php which is newly downloaded wordpress-2.9-ja.zip

I tried wordpress-2.9-ja.zip because the version on the problem was it. Please check before you change the translation.php file.
