Genko yoshi replaces the running line with a grid of boxes, one character to a cell. The pitch runs 9.17 mm, eighteen rows to the page. The box does something a ruled line cannot: it holds the character to a fixed size instead of letting it grow or shrink across a line.
The cells do not care which script goes inside them. Kanji, kana, Hangul practised stroke by stroke, or a Latin hand drilled for consistency all sit inside the same box the same way. What the grid enforces is proportion, not language.
A box does not correct a stroke order or a proportion by itself. It only gives the same box back every time, so a mistake stays visible instead of drifting off the page unnoticed.
