environs, boundary, border, vicinity
辺 centers on the area near a boundary or edge: the environs, vicinity, or border of a place.
辺 is the modern simplified form of 邊. The older form combines 辶 (movement) with 臱, which likely contributed the sound and the idea of a border or edge. The modern 刀 inside is a simplification.
The movement radical 辶 surrounds a sword 刀, like a blade marking the edge of a territory. Picture walking along the border with a sword to define the boundary.
For ヘン, imagine a hen pecking at the ground right at the border of its coop: hen -> ヘン, and the hen marks the edge of its territory.
