noun
garden party
A formal outdoor social gathering, often hosted by an institution or dignitary. In Japan, strongly associated with the Imperial Family's spring and autumn garden parties.
春の園遊会には多くの文化人が招かれる。
Many cultural figures are invited to the spring garden party.
A loanword from English, often used for casual or Western-style outdoor parties, while 園遊会 implies a more formal, often official event.
Compound of 園 (garden) + 遊 (play, enjoy) + 会 (gathering). The term was coined in the Meiji era to translate the Western concept of a garden party, and it became established through imperial events.
