Nakanoshima Rose Garden sits on an island-like strip between two rivers in Kitahama, Osaka. The rose scent is strong from the entrance, and the range of rose varieties makes it a place to aim for peak bloom. You can walk the riverside path between Umeda Station and Osaka Castle, and Osaka City Hall and the Museum of Ceramics are nearby. The garden is not large, so it gets crowded with people during blooming season.
