The Japanese Garden of Montevideo (Spanish: Jardín Japonés de Montevideo; Japanese: モンテビデオの日本庭園) is located in the Prado neighbourhood of Montevideo, behind the Juan Manuel Blanes Museum.
It was donated by Japan as a memorial to the 80th anniversary of the establishment of diplomatic relations between both countries, and inaugurated on 24 September 2001 by Princess Sayako.
A wooden plaque, with calligraphy by then Prime Minister Junichiro Koizumi, bears the inscription 平成苑 "Heisei Garden", being the year 13 of the Heisei Era (reign of Akihito) the moment of the inauguration.
