About the English editionWork in progress
10 of 180 articles are in English so far.
Articles appear in English only after they have been written and checked in English. Nothing is machine-translated behind the scenes, and an English URL is never created for an article that has no English text. Everything else stays available in Japanese, and each guide lists both.
Five guides.
