This script was originally created for the JLU (Japanese Language and Usage) site as part of the Creating as much Japanese interface as possible to be more inclusive of native Japanese speakers meta page, but it now should work on all the major Stack Exchange sites.
To change to Japanese, click the
日本語版 icon which will appear in the top right corner of every page.
It's a work in progress, but a fairly large amount of the site has been translated including UI elements, tooltips, dates, some messages, Stack Exchange badges+descriptions, tags on the JLU site etc. For the current status, please see the GitHub project page.
I'm not a Japanese native speaker and there are probably lots of errors remaining. If anyone could give any assistance correcting or contributing to the translation I'd much appreciate it (many thanks to @ento for checking some of the translations!)

The platforms I'm currently testing it on are Firefox 16.0.1 with Greasemonkey and Chromium "20.0.1132.47 Ubuntu 12.04 (144678)". I hope to support IE, Safari and Opera one of these days too.
Please leave a comment or post an answer here and I'll try to respond as quickly as possible.
