How to say "preface" in Japanese

Choosing the right word
  • 前置きまえおきJLPT N1approx.Common
    noun, suru verb, intransitive verbThe general word for remarks made before the main subject, spoken or written. Use it for preliminaries or a preamble — what a speaker gets out of the way before the talk proper.
    彼かれは前置まえおきとして、すこし話はなした。↗
    He said a few words by way of preface.
  • 序章じょしょうCommon
    nounLiterally an opening chapter: use it for the introductory chapter of a novel, thesis, or similar work — when 'preface' means a chapter of the book itself rather than a note before the text.
  • 序文じょぶんCommon
    nounThe preface or foreword of a book: a self-contained text at the front setting out the work's purpose and background, whether written by the author or by someone else.
    彼かれはその戯曲ぎきょくにすばらしい序文じょぶんを書かいた。↗
    He wrote a fine preface to the play.
  • 前書きまえがきCommon
    nounA preface or foreword written at the front of a book, near-synonymous with 序文; it is also used for a short introductory note heading an individual piece or entry.
  • 枕詞まくらことばCommon
    nounBest known as a name for the fixed epithets of classical poetry; its 'preface' sense is figurative — lead-in remarks before the main subject — and it is seldom the word you want for a book's preface.

For a book's preface or foreword choose 序文 or 「前書き」; 序章 is the introductory chapter of a work; 「前置き」 covers preliminary remarks before the main subject; 枕詞 is chiefly a term of classical poetry, only figuratively an introduction.
