noun
A person who goes to see an exhibition, show, or event. Slightly formal; often used in contexts like museums, galleries, or public displays.
展覧会の観覧者は、静かに作品を見ていた。
The spectators at the exhibition were quietly viewing the works.
この美術館は一日に多くの観
This museum welcomes many visitors each day.
見物人 is a casual term for sightseers or onlookers, whereas 観覧者 is more formal and specific to organized viewings.
Compound of 観覧 (viewing, inspection) + 者 (person). The exact historical derivation is uncertain, but the word follows a common Sino-Japanese pattern for agent nouns.
