"Diagraph01" lives in Tokyo, Japan. ja.wp's admin from 7 May 2006.
I'm taking the [[:ja:Wikipedia:多言語の統計|Multilingual statistics (ja)]] and [[:ja:Wikipedia:ウィキペディアが提供されている言語の総覧|List of Wikipedias (ja)]] in Japanese wikipedia. Although, I think that it will concentrate on acquisition each language information and attachment "+interwiki" for the time being. Therefore, I can't write new contribution.
