境界 (kyōkai) is the most versatile for physical and abstract boundaries. 境 (sakai) is more colloquial and often refers to a tangible dividing line. 区別 (kubetsu) is strictly for distinguishing between concepts or categories, not physical borders.
The English word 'demarcation' is often translated as 境界設定 (kyōkai settei) or 画定 (kakutei) in formal contexts, but these can sound overly technical. In everyday Japanese, it's more natural to use simpler terms like 境界 or 区別 depending on the context.
