How to say "documentation" in Japanese

Choosing the right word
  • nounThe straightforward loanword for documentation as written materials, including software manuals and project records. It is less common than native alternatives, so it is not always the word Japanese speakers reach for.
  • 文献集ぶんけんしゅう
    nounCovers documentation in the sense of a collection of written sources or literature on a subject. It is a poor choice for everyday documentation such as manuals; it really means an anthology of reference texts.
  • 文書化ぶんしょか
    noun, suru verbDenotes documentation as the act or result of turning something into written documents, for example recording procedures or agreements. Use it when the emphasis is on making things official in written form.
  • 身分事項みぶんじこう
    nounRefers to personal identification details rather than documentation in general. It is only marginally applicable, appearing in official or legal contexts concerning matters used to identify a person.
  • 証拠書類しょうこしょるい
    nounMeans documentary evidence: papers that serve as proof in a legal, official, or investigative setting. It suits documentation only when the documents function as evidence, not for manuals or records generally.

Choose 「ドキュメンテーション」 for general documentary or software documentation, 文書化 for the act of putting things in writing, 文献集 for a collection of literature, and 証拠書類 or 身分事項 for evidentiary or identification papers.
