権 is the modern simplified form of 權. The older form combines 木 (wood) with 雚, which likely contributed the sound and originally referred to a type of tree or a scale beam, later extended to the idea of weighing authority.
The left side is a tree 木, and the right side looks like a bird 隹 with an arrow 矢 above it. Imagine a chief holding a wooden staff topped with a bird-and-arrow emblem as a symbol of authority and rights.
For ケン, picture a powerful official named Ken holding the wooden staff of authority: Ken -> ケン, and his power is recognized by all.
