noun
Refers to a person who wanders from place to place without a fixed home or job; can carry a literary or slightly old-fashioned tone.
彼は若い頃、放浪者として日本中を旅した。
When he was young, he traveled all over Japan as a vagabond.
駅の近くに放浪者が座
A drifter was sitting near the station.
流浪者 is more literary and often suggests a longer, aimless journey, sometimes with a sense of exile.
Compound of 放浪 (wandering) + 者 (person). The exact historical derivation is uncertain, but the kanji composition directly reflects the meaning.
