Shirasagi Park, located in Higashi Ward, Sakai City, has a site area of approximately 90,000 square meters.
The vast park includes an athletic field, a baseball field, and a playground, and is used by a wide range of people, from children to the elderly, for sports and recreation.
In 1989, to commemorate the 100th anniversary of Sakai City's municipal incorporation, the iris was selected by public vote as the city's flower, and an iris garden was established within the park.
It has now become widely known as a famous flower viewing spot.
Every year from late May to early June, irises bloom, delighting the eyes of visitors.
