noun
paradise; land of ease; utopia
Literary or figurative term for an ideal, trouble-free place. Often used in contrast to a harsh reality.
この世に楽土はない。
There is no paradise in this world.
彼は都会を離れ、田舎に楽土を求めた。
He left the city and sought a land of ease in the countryside.
Compound of 楽 (らく, 'ease, comfort') and 土 (ど, 'land, soil'). The exact historical derivation is uncertain, but the word follows a common Sino-Japanese pattern for naming idealized places.
