noun
A person who has withdrawn from public life to live in seclusion, often with a nuance of principled retirement or escape from worldly affairs. Somewhat literary.
彼は政界を去り、逸民として静かに暮らした。
He left the political world and lived quietly as a recluse.
その逸民は山奥で一人、読書にふけっていた。
The retired person lived alone deep in the mountains, absorbed in reading.
From Chinese 逸民 (yìmín), combining 逸 'escape, leisure' and 民 'people'. The exact historical derivation is uncertain, but the term has been used in classical Chinese and Japanese texts to refer to hermits or retired scholars.
