Japanese quotation marks (「」/『』)

The Japanese punctuation device for marking quoted material: 「...」 (kagi-kakko, 'hook brackets') for primary quotation — direct speech, dialogue, titles inline — and 『...』 (nijuukagi-kakko, 'double hook brackets') for nested quotes inside an outer 「」 or, in some authorial styles, as the primary quote bracket itself. Vertical-script-friendly. A typographic convention rather than a syntactic feature, distinct from the title-specific use of 『』 captured in syntax.
