You need to install an East Asian language pack. See below for instructions.
Genko Settings
Genko settings, short for genkō yōshi, refers to the Japanese term for paper lightly printed with square grid background to assist positioning of writing East Asian characters. The feature is derived from writing or manuscript paper which uses a grid or squares; such sheets are often divided into 200 or 400 squares. Each space is used for one character. This feature is available in Word.
Instructions for Word
East Asian versions of Office will have this feature by default. If you don't have one of these versions, you must first install an East Asian language pack.
Ensure one East Asian Language set as your default editing language, as explained in My Language Preferences: Office Editing Languages.
NOTE: The language you select will determine the default Genko settings; for example, Korean has slightly different settings than Chinese and Japanese.
Go to the Page Layout tab of the Ribbon.
In the Genko chunk, click on the Genko Setting button.
You will be able to specify whether to use a line grid or line-and-character grid to control formatting and what measurements are used for the grid so that you can enter characters by using fixed-pitch spacing (as in Genko or Gaozhi formatting).
