CJK pages often appear denser to teams trained on Latin layouts. That density can be an advantage: labels can be shorter, navigation can be compact, and editorial compositions can hold more meaning in less space.
The risk is flattening hierarchy. When every block becomes equally dense, the page loses scanability. Use scale, weight, color, and empty space to build moments of pause.
For dashboards and commerce pages, test with the longest real labels in Chinese, Japanese, and Korean. A beautiful Latin component can collapse when translated if its constraints were never designed for CJK rhythm.
