A long-established park that opened in 1934 using the riverbed of the Yodo River. The 9.5 hectare park is famous for its cherry blossoms in April and the ``Johoku Chrysanthemum Exhibition'' held around November every year, both of which are popular Osaka sights. In particular, the ``Iris Garden'' is home to approximately 13,000 plants of approximately 250 types of irises of three lines: Edo, Ise, and Higo, where they bloom in a variety of colors, from May to June, when they bloom in blue-purple, white, and yellow. It has also been selected as one of the ``100 best green areas in Osaka.'' Furthermore, just below the Yodo River embankment, there is a bay area (a pond-like area along a river surrounded by canals), where rare plants and animals gather. It would be nice to take a walk while observing nature up close.
