noun, na-adjective
Literary term for a state of deep boredom or weariness with life; often used in classical or formal writing.
彼は無聊をかこつ日々を送っていた。
He spent his days complaining of boredom.
noun, na-adjective
discontent; unease
Rare literary nuance of dissatisfaction or restlessness; overlaps with sense 1 but emphasizes emotional unease rather than simple boredom.
無聊の念に駆られて、彼は旅に出た。
Driven by a feeling of discontent, he set out on a journey.
From Chinese 無聊 (wúliáo), meaning 'having nothing to rely on' or 'bored'. The Japanese reading ぶりょう is the standard Sino-Japanese reading; むりょう is an obsolete variant.
