向(む)きSuitable for, Facing

Both can be translated as 'for (A)', but differ in nuance. 向き attaches directly to a noun and suggests suitability, e.g. 子ども向きの本 ('A book suitable for children') ため(に) connects to nouns with の and suggests intended benefit or purpose, e.g. 子どものための本 ('A book for children [designed to benefit them]')

These expressions all involve direction or suitability, but differ in usage. に向かって・に向けて describe motion or intent toward a goal or target, e.g. 'ゴールに向かって走る' ('run toward the goal'). 向き attaches directly to a noun and refers to the appropriateness or orientation of something for a group, without necessarily implying targeted action, e.g. '初心者向きのコース' ('a course suited for beginners').

Both relate to the idea of being suited to something else, but with different nuances. に合わせて・に合った implies active adjustment to suit a person or situation, e.g. 季節に合わせて洋服を選ぶ ('Choose clothes to match the season'), while 向き describes suitability or appropriateness by nature, e.g. 初心者向きの本 ('A book suitable for beginners').

Both 向け and 向き describe suitability or orientation, but differ in nuance and intent. 向け refers to something explicitly designed or intended for a specific group or purpose, e.g. '子供向けの番組' ('a program for children'). 向き describes natural suitability without implying deliberate targeting, e.g. '初心者向きのコース' ('a course suited for beginners').
