Daisen Park is approximately 35 hectares in size, located between Daisenryo Kofun (said to be the tomb of Emperor Nintoku) and Kamiishizu Misanzai Kofun (said to be the tomb of Emperor Richu). Located around Heiwa-to (tower of peace) facing the rows of ginkgo at the north entrance and bottle gourd-shaped Dora-ike (pond) that was made from a reservoir dating back to the Edo Period are Shibafu-hiroba (lawned square) and Jido-no-mori (children's forest) where many children play during holidays. There are also other facilities such as the Sakai City Museum where visitors can learn about the history and culture of Sakai City, a Japanese garden with 26,000 square meters in area, Green Center with Hana-to-mizu-no-hiroba (flower and water park), and a teahouse where visitors can enjoy green tea in relaxed style. A tour around the Mozu tumulus cluster dispersed within and around the park is also something that can be experienced only at Daisen Park. In April, approximately 400 someiyoshino and oshimazakura cherry trees all bloom at once, and on the third Saturday of October, the Sakai Festival takes place.
