Translated Documentation/HOWTO into Japanese (and maintain it). It is merged in 2.6.23 and placed at Documentation/ja_JP/HOWTO. At the same time, Chinese and Korean version also merged. So, 2.6.23 becomes a great period to build a bridge from Asian/non-English developer to Linux Kernel development community.
Established http://jp.kernelnewbies.org , jp-kernelnewbies mailing list by great help from Rik. These Web and list are to support Japanese developer to participate real Linux kernel community.
