Adjacent to Hineno's Hineno Shrine, this park is rich in natural beauty and spreads across the Roji Valley in the middle reaches of the Kashii River, which flows east to west through Izumisano City. In spring, Somei-yoshino cherry trees bloom here, making it a famous cherry blossom viewing spot in Izumisano City. The Cherry Blossom Festival, held every year on the first Saturday of April by the Izumisano City Tourist Association, is a popular event that draws many visitors. Roji Valley, where you can enjoy the clear stream at the bottom of the valley and the impressive rock formations, has been selected as one of the "100 Best Green Spots in Osaka," and the view from the arched bridge in the park is particularly spectacular. Many people visit in the summer to cool off. A walking path has been built on the embankment near the park, making it a popular spot among locals. It is convenient to take a bus from Izumisano Station on the Nankai Railway or Hineno Station on the JR Lines and get off at the Tojo stop.
