• Related活動的かつどうてきNeutralEnergetic and always on the go, as in 「活動的な性格」. It stresses vigor, not initiative, so it lacks the sense of acting on one's own that 「能動的」 has.
• Related行動的こうどうてきNeutralDescribes a person who puts things into action, as in 「行動的な人」. It stresses being quick to actually do things rather than the initiative implied by 「能動的」.
