   The problem is one of determining the dominant factors in this phenomenon.

• Related優勢ゆうせいNeutralSays the situation or momentum is in the ascendant, as in 「優勢に立つ」; 「支配的」 stresses holding the leading, ruling position.
• Related主おもNeutralAn adjectival noun meaning 'main', used mostly as 「主な」; it has no nuance of dominating others.
• Related強力きょうりょくNeutralRefers to great strength or potency, as in 「強力な薬」; it centers on strength itself, not on ruling over others.
• Related優位ゆういNeutralMeans being in an advantageous position, as in 「優位に立つ」; it stresses an edge in a comparison rather than dominance.
• Related力強いちからづよいNeutralDescribes something as forceful or vigorous, and can also be reassuring; it is about the impression given, not dominance.
• Related強いつよいNeutralThe most common word for strong or powerful; 「支配的」 adds the nuance of leading and overwhelming others.
• RelatedパワフルNeutralA loanword for brimming with power and energy, used mostly of people, machines and performances; no nuance of dominating others.
• Related有力ゆうりょくNeutralMeans influential or powerful, and also likely or convincing, as in 「有力候補」「有力な証拠」; it does not imply dominance.
• Antonym従属的じゅうぞくてきWrittenA written, formal word for being subordinate to or dependent on another; the direct opposite of 「支配的」.
• Antonym補助的ほじょてきNeutralMeans serving an auxiliary, supporting role; the opposite of 「支配的」, which denotes holding the leading position.

Use 「支配的」 for something dominant that prevails over others, as in 「支配的な意見」. For a situation or contest in the ascendant, say 「優勢」 or 「優位」; for sheer strength or potency, 「強力」. The remaining words stress strength or advantage without the ruling nuance; 「従属的」 and 「補助的」 are the antonyms.
