The Rose Garden in Utsubo Park is the most outstanding rose garden in Osaka. Begun in 1952 as a post-war reconstruction project, the garden was extensively renovated in 2003. The renewed Rose Garden was expanded to 9,000 square metres and contains 3,200 roses in 151 varieties. These range from the wild roses of Japanese and Oriental origin to present-day roses. Colorful, labeled roses are displayed in a natural and harmonious arrangement under the theme "natural and casual". The Rose Garden functions as an urban oasis for the citizens of Osaka.
