noun
freedom; liberty; independence
Literary and somewhat old-fashioned term for being free from restraint or convention. Often used in set phrases like 不羈奔放 or 不羈独立.
彼の生き方はまさに不羈奔放そのものだ。
His way of life is truly free and unrestrained.
不羈独立の精神を大切にする。
I value the spirit of independence and freedom.
From Chinese 不羈 (bùjī), meaning 'unrestrained' or 'unbridled'. The Japanese reading ふき is the on'yomi. The exact historical path into Japanese is uncertain, but it is used in literary and formal writing.
