When should either 「」 and 『』 be used?


In what scenarios would you use 「」 quotation marks instead of 『』, and vice
versa?




In Japanese, the symbols 「」 are called [鉤括弧]{かぎかっこ} and the symbols 『』 are
called [二重鉤括弧]{にじゅうかぎかっこ}. The basic rules for these symbols are simple: 「」 is
used to denote quotation, and 『』 is used to denote quotation inside a
「」-quote.

Example:

> [先生]{せんせい}が[生徒]{せいと}に「『おはよう』はフランス[語]{ご}で[何]{なん}と[言]{い}いますか」と[聞]{き}いた。  
>  A teacher asked a student, “How do you say ‘Good morning’ in French?”

In some contexts, 『』 is also used to denote the title of a book and other
kinds of works.

Example (from
[Wikipedia](http://ja.wikipedia.org/wiki/%E5%BA%83%E8%BE%9E%E8%8B%91) with an
English translation by me):

> 『[広辞苑]{こうじえん}』は、[岩波書店]{いわなみしょてん}が[発行]{はっこう}している[中型国語辞典]{ちゅうがたこくごじてん}である。  
>  “Kōjien” is a middle-sized Japanese dictionary published by Iwanami Shoten,
> Publishers.
