Like printed vertical Japanese, full stops, commas, and small kana are placed in the top right corner of their own square. All punctuation marks, other marks (such as parentheses), and small kana usually occupy their own square, unless this would place them at the top of a new column, in which case they share the last square of the previous column with the character in that square. (This is the kinsoku shori rule.) A full stop followed directly by closing quotation mark are written in one square. A blank square is left after non-Japanese punctuation marks (such as exclamation points and question marks). Ellipses and dashes use two squares.
