  In my analysis I rely considerably on the types of authoritarian behaviour first analyzed by Kurz.
• 独裁主義者どくさいしゅぎしゃ
  nounA less common noun for 'authoritarian' as a person: someone who embraces or practices dictatorial rule. It names a person, so it is not the choice for describing an attitude or manner.
• 強権的きょうけんてき
  na-adjectiveA less common adjective closest in nuance to 'heavy-handed' and 'iron-fisted': it suggests the strong, coercive exercise of power, as in authoritarian rule or measures.

For an authoritarian person use the noun 独裁主義者; for the adjective, 権威的 is the direct equivalent, while 強権的 leans toward 'heavy-handed' and 'iron-fisted'; all three are less common choices.
