This law's whole text runs past 200 KB as Markdown, so its twin here is its table of
contents. Each page of the law below has a twin of its own, at that page's path under /md,
with the same rules: the Japanese and the English of every provision, the source of each
English line, and every provision's address and URLs. Only the Japanese as published by the
government has legal effect.
