How to say "library" in Japanese

Choosing the right word
  • nounA loanword that you will not normally hear for an actual library building; its natural home is technical language, especially computing, where it denotes a stock of reusable program code.
  • 文庫ぶんこCommon
    nounReally a book collection rather than the institution; in practice it appears chiefly as part of proper names, so for a public or school library it is not the word you want — use 図書館.
    それらの書物しょもつで立派りっぱな文庫ぶんこができるだろう。↗
    Those books will make a fine library.
  • 書庫しょこCommon
    nounThe storage side of a library: a room where books are kept, such as the stacks of a large library, rather than the library itself or the public reading facility.
  • 書斎しょさいJLPT N3approx.Common
    nounA private study in the home — a room of one's own for reading and work; its 'library' sense is this personal book room, never a public library.
    このドアは書斎しょさいに通つうじている。↗
    This door leads to the study.
  • 図書館としょかんJLPT N5approx.Common
    nounThe word you use for a library as an institution or facility — public, school, and university libraries alike; when you mean the place itself, this is what to say.
    私わたしたちの学校がっこうには立派りっぱな図書館としょかんがあります。↗
    We have a nice school library.

For a library as an institution, choose 図書館; 書斎 is a private home study, 書庫 a book-storage room, 文庫 a book collection, and 「ライブラリー」 a loanword heard mainly in technical contexts.
