This botanical garden, created in 1933 at an altitude of 865m/2,840ft (average annual temperature 9°C/48°F), is home to over 1,500 species of alpine plants from Japan, some of which are endemic and indigenous to Mount Rokko, and from other mountain regions in the world (Himalayan rhododendrons, Komakusa roses, edelweiss, etc.). This exceptional flora thrives on over 50ha/123acres of slopes and terraces, woodland and forests, rock gardens and a pond, all riddled with paths.
